Batteries are a kind of energy conversion and storage devices that convert chemical or physical energy into electrical energy through reactions. According to the different energy conversion of the battery, the battery can be divided into a chemical battery and a biological battery. A chemical battery or chemical power source is a device that converts chemical energy into electrical energy. It comprises two electrochemically active electrodes with different components, respectively, composed of positive and negative electrodes. A chemical substance that can provide media conduction is used as an electrolyte. When connected to an external carrier, it delivers electrical energy by converting its internal chemical energy. A physical battery is a device that converts physical energy into electrical energy.

Glavna razlika je u tome što je aktivni materijal drugačiji. Aktivni materijal sekundarne baterije je reverzibilan, dok aktivni materijal primarne baterije nije. Samopražnjenje primarne baterije je mnogo manje nego kod sekundarne baterije. Ipak, unutrašnji otpor je mnogo veći od otpora sekundarne baterije, pa je kapacitet opterećenja manji. Osim toga, kapacitet primarne baterije specifičan za masu i zapreminski specifičan kapacitet je značajniji od onih dostupnih punjivih baterija.

Ni-MH batteries use Ni oxide as the positive electrode, hydrogen storage metal as the negative electrode, and lye (mainly KOH) as the electrolyte. When the nickel-hydrogen battery is charged: Positive electrode reaction: Ni(OH)2 + OH- → NiOOH + H2O–e- Adverse electrode reaction: M+H2O +e-→ MH+ OH- When the Ni-MH battery is discharged: Positive electrode reaction: NiOOH + H2O + e- → Ni(OH)2 + OH- Negative electrode reaction: MH+ OH- →M+H2O +e-

The main component of the positive electrode of the lithium-ion battery is LiCoO2, and the negative electrode is mainly C. When charging, Positive electrode reaction: LiCoO2 → Li1-xCoO2 + xLi+ + xe- Negative reaction: C + xLi+ + xe- → CLix Total battery reaction: LiCoO2 + C → Li1-xCoO2 + CLix The reverse reaction of the above reaction occurs during discharge.

Commonly used IEC standards for batteries: The standard for nickel-metal hydride batteries is IEC61951-2: 2003; the lithium-ion battery industry generally follows UL or national standards. Commonly used national standards for batteries: The standards for nickel-metal hydride batteries are GB/T15100_1994, GB/T18288_2000; the standards for lithium batteries are GB/T10077_1998, YD/T998_1999, and GB/T18287_2000. In addition, the commonly used standards for batteries also include the Japanese Industrial Standard JIS C on batteries. IEC, the International Electrical Commission (International Electrical Commission), is a worldwide standardization organization composed of electrical committees of various countries. Its purpose is to promote the standardization of the world's electrical and electronic fields. IEC standards are standards formulated by the International Electrotechnical Commission.

Glavne komponente nikl-metal hidridnih baterija su pozitivna elektroda (nikl oksid), ploča negativne elektrode (legura za skladištenje vodonika), elektrolit (uglavnom KOH), membranski papir, zaptivni prsten, poklopac pozitivne elektrode, kućište baterije itd.

Glavne komponente litijum-jonskih baterija su gornji i donji poklopci baterije, ploča pozitivne elektrode (aktivni materijal je litijum kobalt oksid), separator (posebna kompozitna membrana), negativna elektroda (aktivni materijal je ugljen), organski elektrolit, kućište baterije (podijeljen na dvije vrste čelične ljuske i aluminijske školjke) i tako dalje.

Odnosi se na otpor koji doživljava struja koja teče kroz bateriju dok baterija radi. Sastoji se od omskog unutrašnjeg otpora i polarizacionog unutrašnjeg otpora. Značajan unutrašnji otpor baterije će smanjiti radni napon pražnjenja baterije i skratiti vrijeme pražnjenja. Na unutrašnji otpor uglavnom utiču materijal baterije, proizvodni proces, struktura baterije i drugi faktori. To je važan parametar za mjerenje performansi baterije. Napomena: Generalno, unutrašnji otpor u napunjenom stanju je standard. Za izračunavanje unutrašnjeg otpora baterije treba koristiti poseban mjerač unutrašnjeg otpora umjesto multimetra u rasponu oma.

Nazivni napon baterije odnosi se na napon koji se pokazuje tokom redovnog rada. Nominalni napon sekundarne nikl-kadmijum nikl-vodonik baterije je 1.2V; nominalni napon sekundarne litijumske baterije je 3.6V.

Napon otvorenog kola se odnosi na razliku potencijala između pozitivne i negativne elektrode baterije kada baterija ne radi, odnosno kada struja ne teče kroz kolo. Radni napon, poznat i kao terminalni napon, odnosi se na razliku potencijala između pozitivnog i negativnog pola baterije kada baterija radi, odnosno kada postoji prekomjerna struja u kolu.

Kapacitet baterije se dijeli na nazivnu snagu i stvarnu sposobnost. Nazivni kapacitet baterije odnosi se na odredbu ili garanciju da baterija treba da isprazni minimalnu količinu električne energije pod određenim uslovima pražnjenja tokom projektovanja i proizvodnje oluje. IEC standard propisuje da se nikl-kadmijum i nikl-metal hidridne baterije pune na 0.1C tokom 16 sati i prazne na 0.2C do 1.0V na temperaturi od 20°C±5°C. Nazivni kapacitet baterije izražen je kao C5. Predviđeno je da se litijum-jonske baterije pune 3 sata pod prosječnom temperaturom, konstantna struja (1C)-konstantni napon (4.2V) kontrolišu zahtjevne uslove, a zatim se prazne na 0.2C do 2.75V kada je ispražnjena električna energija nazivnog kapaciteta. Stvarni kapacitet baterije odnosi se na stvarnu snagu koju oslobađa oluja pod određenim uslovima pražnjenja, na koju uglavnom utiču brzina pražnjenja i temperatura (tako striktno govoreći, kapacitet baterije treba da odredi uslove punjenja i pražnjenja). Jedinica kapaciteta baterije je Ah, mAh (1Ah=1000mAh).

Kada se punjiva baterija isprazni velikom strujom (kao što je 1C ili više), zbog "efekta uskog grla" koji postoji u internoj brzini difuzije strujne prekomjerne struje, baterija je dostigla terminalni napon kada kapacitet nije potpuno ispražnjen , a zatim koristi malu struju kao što je 0.2C može nastaviti s uklanjanjem, sve dok 1.0V/komadu (nikl-kadmijum i nikl-hidrogen baterija) i 3.0V/komadu (litijumska baterija), oslobođeni kapacitet se naziva preostali kapacitet.

Platforma za pražnjenje Ni-MH punjivih baterija se obično odnosi na opseg napona u kojem je radni napon baterije relativno stabilan kada se prazni pod određenim sistemom pražnjenja. Njegova vrijednost je povezana sa strujom pražnjenja. Što je struja veća, to je težina manja. Platforma za pražnjenje litijum-jonskih baterija je generalno da prestane da se puni kada je napon 4.2V, a sadašnji je manji od 0.01C pri konstantnom naponu, zatim se ostavi 10 minuta i isprazni do 3.6V pri bilo kojoj brzini pražnjenja. struja. To je neophodan standard za mjerenje kvaliteta baterija.

When the battery voltage rises to a specific value, the voltage remains unchanged (CV), and the wind in the circuit drops to a small amount, eventually tending to zero. Lithium battery charging method: Constant current and constant voltage charging: The battery is first charged with constant current (CC). When the battery voltage rises to a specific value, the voltage remains unchanged (CV), and the wind in the circuit drops to a small amount, eventually tending to zero.

Međunarodni standard IEC propisuje da je standardno punjenje i pražnjenje nikl-metal hidridnih baterija: prvo ispraznite bateriju na 0.2C do 1.0V po komadu, zatim punite na 0.1C 16 sati, ostavite je 1 sat i stavite je na 0.2C do 1.0V/komad, što je za punjenje i pražnjenje baterije standard.

Pulsno punjenje općenito koristi punjenje i pražnjenje, postavljanje na 5 sekundi, a zatim otpuštanje na 1 sekundu. On će smanjiti većinu kiseonika koji se stvara tokom procesa punjenja u elektrolite pod impulsom pražnjenja. Ne samo da ograničava količinu unutrašnjeg isparavanja elektrolita, već će se stare baterije koje su jako polarizirane postupno oporaviti ili približiti izvornom kapacitetu nakon 5-10 puta punjenja i pražnjenja korištenjem ove metode punjenja.

Punjenje se koristi da se nadoknadi gubitak kapaciteta uzrokovan samopražnjenjem baterije nakon što je potpuno napunjena. Općenito, pulsno punjenje se koristi za postizanje gore navedene svrhe.

Efikasnost punjenja se odnosi na mjeru stepena do kojeg se električna energija koju troši baterija tokom procesa punjenja pretvara u hemijsku energiju koju baterija može pohraniti. Na to uglavnom utiču tehnologija baterije i temperatura radnog okruženja oluje – generalno, što je temperatura okoline viša, to je niža efikasnost punjenja.

Efikasnost pražnjenja se odnosi na stvarnu snagu ispražnjenu na terminalnom naponu pod određenim uslovima pražnjenja do nazivnog kapaciteta. Na njega uglavnom utiču brzina pražnjenja, temperatura okoline, unutrašnji otpor i drugi faktori. Općenito, što je veća brzina pražnjenja, to je veća brzina pražnjenja. Što je niža efikasnost pražnjenja. Što je niža temperatura, to je niža efikasnost pražnjenja.

The output power of a battery refers to the ability to output energy per unit time. It is calculated based on the discharge current I and the discharge voltage, P=U*I, the unit is watts. The lower the internal resistance of the battery, the higher the output power. The internal resistance of the battery should be less than the internal resistance of the electrical appliance. Otherwise, the battery itself consumes more power than the electrical appliance, which is uneconomical and may damage the battery.

Self-discharge is also called charge retention capability, which refers to the retention capability of the battery's stored power under certain environmental conditions in an open circuit state. Generally speaking, self-discharge is mainly affected by manufacturing processes, materials, and storage conditions. Self-discharge is one of the main parameters to measure battery performance. Generally speaking, the lower the storage temperature of the battery, the lower the self-discharge rate, but it should also note that the temperature is too low or too high, which may damage the battery and become unusable. After the battery is fully charged and left open for some time, a certain degree of self-discharge is average. The IEC standard stipulates that after fully charged, Ni-MH batteries should be left open for 28 days at a temperature of 20℃±5℃ and humidity of (65±20)%, and the 0.2C discharge capacity will reach 60% of the initial total.

The self-discharge test of lithium battery is: Generally, 24-hour self-discharge is used to test its charge retention capacity quickly. The battery is discharged at 0.2C to 3.0V, constant current. Constant voltage is charged to 4.2V, cut-off current: 10mA, after 15 minutes of storage, discharge at 1C to 3.0 V test its discharge capacity C1, then set the battery with constant current and constant voltage 1C to 4.2V, cut-off current: 10mA, and measure 1C capacity C2 after being left for 24 hours. C2/C1*100% should be more significant than 99%.

The internal resistance in the charged state refers to the internal resistance when the battery is 100% fully charged; the internal resistance in the discharged state refers to the internal resistance after the battery is fully discharged. Generally speaking, the internal resistance in the discharged state is not stable and is too large. The internal resistance in the charged state is more minor, and the resistance value is relatively stable. During the battery's use, only the charged state's internal resistance is of practical significance. In the later period of the battery's help, due to the exhaustion of the electrolyte and the reduction of the activity of internal chemical substances, the battery's internal resistance will increase to varying degrees.

Statički unutrašnji otpor je unutrašnji otpor baterije tokom pražnjenja, a dinamički unutrašnji otpor je unutrašnji otpor baterije tokom punjenja.

The IEC stipulates that the standard overcharge test for nickel-metal hydride batteries is: Discharge the battery at 0.2C to 1.0V/piece, and charge it continuously at 0.1C for 48 hours. The battery should have no deformation or leakage. After overcharge, the discharge time from 0.2C to 1.0V should be more than 5 hours.

IEC stipulates that the standard cycle life test of nickel-metal hydride batteries is: After the battery is placed at 0.2C to 1.0V/pc 01) Charge at 0.1C for 16 hours, then discharge at 0.2C for 2 hours and 30 minutes (one cycle) 02) Charge at 0.25C for 3 hours and 10 minutes, and discharge at 0.25C for 2 hours and 20 minutes (2-48 cycles) 03) Charge at 0.25C for 3 hours and 10 minutes, and release to 1.0V at 0.25C (49th cycle) 04) Charge at 0.1C for 16 hours, put it aside for 1 hour, discharge at 0.2C to 1.0V (50th cycle). For nickel-metal hydride batteries, after repeating 400 cycles of 1-4, the 0.2C discharge time should be more significant than 3 hours; for nickel-cadmium batteries, repeating a total of 500 cycles of 1-4, the 0.2C discharge time should be more critical than 3 hours.

Refers to the internal air pressure of the battery, which is caused by the gas generated during the charging and discharging of the sealed battery and is mainly affected by battery materials, manufacturing processes, and battery structure. The main reason for this is that the gas generated by the decomposition of moisture and organic solution inside the battery accumulates. Generally, the internal pressure of the battery is maintained at an average level. In the case of overcharge or over-discharge, the internal pressure of the battery may increase: For example, overcharge, positive electrode: 4OH--4e → 2H2O + O2↑; ① The generated oxygen reacts with the hydrogen precipitated on the negative electrode to produce water 2H2 + O2 → 2H2O ② If the speed of reaction ② is lower than that of reaction ①, the oxygen generated will not be consumed in time, which will cause the internal pressure of the battery to rise.

IEC stipulates that the standard charge retention test for nickel-metal hydride batteries is: After putting the battery at 0.2C to 1.0V, charge it at 0.1C for 16 hours, store it at 20℃±5℃ and humidity of 65%±20%, keep it for 28 days, then discharge it to 1.0V at 0.2C, and Ni-MH batteries should be more than 3 hours. The national standard stipulates that the standard charge retention test for lithium batteries is: (IEC has no relevant standards) the battery is placed at 0.2C to 3.0/piece, and then charged to 4.2V at a constant current and voltage of 1C, with a cut-off wind of 10mA and a temperature of 20 After storing for 28 days at ℃±5℃, discharge it to 2.75V at 0.2C and calculate the discharge capacity. Compared with the battery's nominal capacity, it should be no less than 85% of the initial total.

The high temperature and humidity test of Ni-MH battery are: After the battery is fully charged, store it under constant temperature and humidity conditions for several days, and observe no leakage during storage. The high temperature and high humidity test of lithium battery is: (national standard) Charge the battery with 1C constant current and constant voltage to 4.2V, cut-off current of 10mA, and then put it in a continuous temperature and humidity box at (40±2)℃ and relative humidity of 90%-95% for 48h, then take out the battery in (20 Leave it at ±5)℃ for two h. Observe that the appearance of the battery should be standard. Then discharge to 2.75V at a constant current of 1C, and then perform 1C charging and 1C discharge cycles at (20±5)℃ until the discharge capacity Not less than 85% of the initial total, but the number of cycles is not more than three times.

At present, nickel-cadmium, nickel-metal hydride, and lithium-ion rechargeable batteries are widely used in various portable electrical equipment (such as notebook computers, cameras, and mobile phones). Each rechargeable battery has its unique chemical properties. The main difference between nickel-cadmium and nickel-metal hydride batteries is that the energy density of nickel-metal hydride batteries is relatively high. Compared with batteries of the same type, the capacity of Ni-MH batteries is twice that of Ni-Cd batteries. This means that the use of nickel-metal hydride batteries can significantly extend the working time of the equipment when no additional weight is added to the electrical equipment. Another advantage of nickel-metal hydride batteries is that they significantly reduce the "memory effect" problem in cadmium batteries to use nickel-metal hydride batteries more conveniently. Ni-MH batteries are more environmentally friendly than Ni-Cd batteries because there are no toxic heavy metal elements inside. Li-ion has also quickly become a common power source for portable devices. Li-ion can provide the same energy as Ni-MH batteries but can reduce weight by about 35%, suitable for electrical equipment such as cameras and laptops. It is crucial. Li-ion has no "memory effect," The advantages of no toxic substances are also essential factors that make it a common power source. It will significantly reduce the discharge efficiency of Ni-MH batteries at low temperatures. Generally, the charging efficiency will increase with the increase of temperature. However, when the temperature rises above 45°C, the performance of rechargeable battery materials at high temperatures will degrade, and it will significantly shorten the battery's cycle life.

Brzina pražnjenja se odnosi na odnos brzine između struje pražnjenja (A) i nazivnog kapaciteta (A•h) tokom sagorevanja. Pražnjenje po satu odnosi se na sate potrebne za pražnjenje nazivnog kapaciteta pri određenoj izlaznoj struji.

Since the battery in a digital camera has a low temperature, the active material activity is significantly reduced, which may not provide the camera's standard operating current, so outdoor shooting in areas with low temperature, especially. Pay attention to the warmth of the camera or battery.

Punjenje -10—45℃ Pražnjenje -30—55℃

Ako pomiješate nove i stare baterije različitih kapaciteta ili ih koristite zajedno, može doći do curenja, nultog napona itd. To je zbog razlike u snazi ​​tokom procesa punjenja, što uzrokuje da se neke baterije prepune tokom punjenja. Neke baterije nisu potpuno napunjene i imaju kapacitet tokom pražnjenja. Baterija visokog kapaciteta nije potpuno ispražnjena, a baterija malog kapaciteta je previše ispražnjena. U takvom začaranom krugu baterija je oštećena, curi ili ima nizak (nulti) napon.

Spajanje dva vanjska kraja baterije na bilo koji provodnik će uzrokovati vanjski kratki spoj. Kratak tok može dovesti do ozbiljnih posljedica za različite tipove baterija, kao što su porast temperature elektrolita, povećanje unutrašnjeg tlaka zraka, itd. Ako tlak zraka premašuje otporni napon poklopca baterije, baterija će procuriti. Ova situacija ozbiljno oštećuje bateriju. Ako sigurnosni ventil pokvari, može čak uzrokovati eksploziju. Stoga, nemojte praviti kratki spoj na bateriji spolja.

01) Charging: When choosing a charger, it is best to use a charger with correct charging termination devices (such as anti-overcharge time devices, negative voltage difference (-V) cut-off charging, and anti-overheating induction devices) to avoid shortening the battery life due to overcharging. Generally speaking, slow charging can prolong the service life of the battery better than fast charging. 02) Discharge: a. The depth of discharge is the main factor affecting battery life. The higher the depth of release, the shorter the battery life. In other words, as long as the depth of discharge is reduced, it can significantly extend the battery's service life. Therefore, we should avoid over-discharging the battery to a very low voltage. b. When the battery is discharged at a high temperature, it will shorten its service life. c. If the designed electronic equipment cannot completely stop all current, if the equipment is left unused for a long time without taking out the battery, the residual current will sometimes cause the battery to be excessively consumed, causing the storm to over-discharge. d. When using batteries with different capacities, chemical structures, or different charge levels, as well as batteries of various old and new types, the batteries will discharge too much and even cause reverse polarity charging. 03) Storage: If the battery is stored at a high temperature for a long time, it will attenuate its electrode activity and shorten its service life.

Ako neće koristiti električni uređaj duži period, najbolje je izvaditi bateriju i staviti je na niskotemperaturno, suho mjesto. Ako nije, čak i ako je električni uređaj isključen, sistem će i dalje učiniti da baterija ima nisku izlaznu struju, što će skratiti vijek trajanja oluje.

According to the IEC standard, it should store the battery at a temperature of 20℃±5℃ and humidity of (65±20)%. Generally speaking, the higher the storage temperature of the storm, the lower the remaining rate of capacity, and vice versa, the best place to store the battery when the refrigerator temperature is 0℃-10℃, especially for primary batteries. Even if the secondary battery loses its capacity after storage, it can be recovered as long as it is recharged and discharged several times. In theory, there is always energy loss when the battery is stored. The inherent electrochemical structure of the battery determines that the battery capacity is inevitably lost, mainly due to self-discharge. Usually, the self-discharge size is related to the solubility of the positive electrode material in the electrolyte and its instability (accessible to self-decompose) after being heated. The self-discharge of rechargeable batteries is much higher than that of primary batteries. If you want to store the battery for a long time, it is best to put it in a dry and low-temperature environment and keep the remaining battery power at about 40%. Of course, it is best to take out the battery once a month to ensure the excellent storage condition of the storm, but not to completely drain the battery and damage the battery.

A battery that is internationally prescribed as a standard for measuring potential (potential). It was invented by American electrical engineer E. Weston in 1892, so it is also called Weston battery. The positive electrode of the standard battery is the mercury sulfate electrode, the negative electrode is cadmium amalgam metal (containing 10% or 12.5% ​​cadmium), and the electrolyte is acidic, saturated cadmium sulfate aqueous solution, which is saturated cadmium sulfate and mercurous sulfate aqueous solution.

01) External short circuit or overcharge or reverse charge of the battery (forced over-discharge); 02) The battery is continuously overcharged by high-rate and high-current, which causes the battery core to expand, and the positive and negative electrodes are directly contacted and short-circuited; 03) The battery is short-circuited or slightly short-circuited. For example, improper placement of the positive and negative poles causes the pole piece to contact the short circuit, positive electrode contact, etc.

01) Whether a single battery has zero voltage; 02) The plug is short-circuited or disconnected, and the connection to the plug is not good; 03) Desoldering and virtual welding of lead wire and battery; 04) The internal connection of the battery is incorrect, and the connection sheet and the battery are leaked, soldered, and unsoldered, etc.; 05) The electronic components inside the battery are incorrectly connected and damaged.

To prevent the battery from being overcharged, it is necessary to control the charging endpoint. When the battery is complete, there will be some unique information that it can use to judge whether the charging has reached the endpoint. Generally, there are the following six methods to prevent the battery from being overcharged: 01) Peak voltage control: Determine the end of charging by detecting the peak voltage of the battery; 02) dT/DT control: Determine the end of charging by detecting the peak temperature change rate of the battery; 03) △T control: When the battery is fully charged, the difference between the temperature and the ambient temperature will reach the maximum; 04) -△V control: When the battery is fully charged and reaches a peak voltage, the voltage will drop by a particular value; 05) Timing control: control the endpoint of charging by setting a specific charging time, generally set the time required to charge 130% of the nominal capacity to handle;

01) Zero-voltage battery or zero-voltage battery in the battery pack; 02) The battery pack is disconnected, the internal electronic components and the protection circuit is abnormal; 03) The charging equipment is faulty, and there is no output current; 04) External factors cause the charging efficiency to be too low (such as extremely low or extremely high temperature).
