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.

Tofauti kuu ni kwamba nyenzo za kazi ni tofauti. Nyenzo inayotumika ya betri ya pili inaweza kutenduliwa, wakati nyenzo hai ya betri ya msingi haiwezi kutenduliwa. Kujitoa kwa betri ya msingi ni ndogo sana kuliko ile ya betri ya pili. Bado, upinzani wa ndani ni mkubwa zaidi kuliko ule wa betri ya sekondari, hivyo uwezo wa mzigo ni wa chini. Kwa kuongeza, uwezo mahususi wa wingi na ujazo maalum wa betri ya msingi ni muhimu zaidi kuliko betri zinazoweza kuchajiwa tena.

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.

Sehemu kuu za betri za nickel-chuma hidridi ni karatasi chanya ya electrode (oksidi ya nikeli), karatasi hasi ya electrode (aloi ya hifadhi ya hidrojeni), electrolyte (hasa KOH), karatasi ya diaphragm, pete ya kuziba, kofia nzuri ya electrode, kesi ya betri, nk.

Sehemu kuu za betri za lithiamu-ioni ni vifuniko vya juu na chini vya betri, karatasi chanya ya elektrodi (nyenzo hai ni oksidi ya lithiamu cobalt), kitenganishi (utando maalum wa mchanganyiko), elektrodi hasi (nyenzo hai ni kaboni), elektroliti ya kikaboni, kesi ya betri. (imegawanywa katika aina mbili za ganda la chuma na ganda la alumini) na kadhalika.

Inarejelea ukinzani unaopatikana na mkondo unaopita kupitia betri wakati betri inafanya kazi. Inaundwa na upinzani wa ndani wa ohmic na upinzani wa ndani wa polarization. Upinzani mkubwa wa ndani wa betri utapunguza voltage ya kazi ya kutokwa kwa betri na kufupisha muda wa kutokwa. Upinzani wa ndani huathiriwa zaidi na nyenzo za betri, mchakato wa utengenezaji, muundo wa betri, na mambo mengine. Ni kigezo muhimu cha kupima utendaji wa betri. Kumbuka: Kwa ujumla, upinzani wa ndani katika hali ya kushtakiwa ni kiwango. Ili kuhesabu upinzani wa ndani wa betri, inapaswa kutumia mita maalum ya upinzani wa ndani badala ya multimeter katika safu ya ohm.

Voltage ya jina la betri inahusu voltage iliyoonyeshwa wakati wa operesheni ya kawaida. Voltage ya nominella ya betri ya sekondari ya nickel-cadmium nickel-hidrojeni ni 1.2V; voltage nominella ya betri ya sekondari ya lithiamu ni 3.6V.

Voltage ya mzunguko wazi inahusu tofauti inayoweza kutokea kati ya elektrodi chanya na hasi za betri wakati betri haifanyi kazi, ambayo ni, wakati hakuna sasa inapita kupitia mzunguko. Voltage ya kufanya kazi, pia inajulikana kama voltage ya mwisho, inarejelea tofauti inayoweza kutokea kati ya nguzo chanya na hasi ya betri wakati betri inafanya kazi, ambayo ni, wakati mzunguko unazidi kupita kiasi.

Uwezo wa betri umegawanywa katika nguvu iliyokadiriwa na uwezo halisi. Uwezo uliokadiriwa wa betri unarejelea masharti au hakikisho kwamba betri inapaswa kutoa kiwango cha chini cha umeme chini ya hali fulani za kutokwa wakati wa kubuni na kutengeneza dhoruba. Kiwango cha IEC kinabainisha kuwa betri za nikeli-cadmium na hidridi ya nikeli-metali huchajiwa kwa 0.1C kwa saa 16 na kutolewa kwa 0.2C hadi 1.0V kwa joto la 20°C±5°C. Uwezo uliokadiriwa wa betri unaonyeshwa kama C5. Betri za lithiamu-ioni zimeainishwa kutoza chaji kwa saa 3 chini ya halijoto ya wastani, hali ya uhitaji ya sasa (1C) -voltage ya mara kwa mara (4.2V) inadhibitiwa, na kisha kutokezwa kwa 0.2C hadi 2.75V wakati umeme unaotolewa unakadiriwa uwezo. Uwezo halisi wa betri unahusu nguvu halisi iliyotolewa na dhoruba chini ya hali fulani ya kutokwa, ambayo inathiriwa zaidi na kiwango cha kutokwa na joto (hivyo kwa ukali, uwezo wa betri unapaswa kutaja hali ya malipo na kutokwa). Kitengo cha uwezo wa betri ni Ah, mAh (1Ah=1000mAh).

Wakati betri inayoweza kuchajiwa inapotolewa kwa mkondo mkubwa (kama vile 1C au zaidi), kwa sababu ya "athari ya chupa" iliyopo katika kiwango cha uenezaji wa ndani wa mkondo wa sasa, betri imefikia voltage ya mwisho wakati uwezo haujatolewa kikamilifu. , na kisha hutumia mkondo mdogo kama vile 0.2C inaweza kuendelea kutoa, hadi 1.0V/kipande (nikeli-cadmium na betri ya nikeli-hidrojeni) na 3.0V/kipande (betri ya lithiamu), uwezo uliotolewa unaitwa uwezo wa mabaki.

Jukwaa la kutokwa kwa betri za Ni-MH zinazoweza kuchajiwa kwa kawaida hurejelea masafa ya voltage ambayo voltage ya kufanya kazi ya betri ni thabiti inapotolewa chini ya mfumo maalum wa kutokwa. Thamani yake inahusiana na sasa ya kutokwa. Ya sasa kubwa, chini ya uzito. Jukwaa la kutokwa kwa betri za lithiamu-ioni kwa ujumla ni kuacha kuchaji wakati voltage ni 4.2V, na sasa ni chini ya 0.01C kwa voltage ya mara kwa mara, kisha iache kwa dakika 10, na kutokwa hadi 3.6V kwa kiwango chochote cha kutokwa. sasa. Ni kiwango muhimu kupima ubora wa betri.

Kiwango cha kimataifa cha IEC kinasema kwamba kiwango cha kawaida cha kuchaji na kutoa betri za hidridi ya nikeli-metali ni: kwanza toa betri kwa 0.2C hadi 1.0V/kipande, kisha chaji kwa 0.1C kwa saa 16, iache kwa saa 1, na kuiweka. kwa 0.2C hadi 1.0V/kipande, hiyo ni Kuchaji na kutekeleza kiwango cha betri.

Kuchaji mapigo kwa ujumla hutumia kuchaji na kutoa, kuweka kwa sekunde 5 na kisha kuachia kwa sekunde 1. Itapunguza oksijeni nyingi inayozalishwa wakati wa mchakato wa kuchaji kwa elektroliti chini ya mapigo ya kutokwa. Sio tu kwamba inapunguza kiwango cha uvukizi wa elektroliti ndani, lakini betri hizo za zamani ambazo zimechanganuliwa sana zitapona polepole au kukaribia uwezo wa asili baada ya mara 5-10 za kuchaji na kutoa kwa kutumia njia hii ya kuchaji.

Kuchaji kwa trickle hutumika kufidia upotezaji wa uwezo unaosababishwa na chaji ya betri baada ya kuchaji kikamilifu. Kwa ujumla, malipo ya sasa ya mapigo hutumiwa kufikia madhumuni yaliyo hapo juu.

Ufanisi wa kuchaji hurejelea kipimo cha kiwango ambacho nishati ya umeme inayotumiwa na betri wakati wa mchakato wa kuchaji inabadilishwa kuwa nishati ya kemikali ambayo betri inaweza kuhifadhi. Inaathiriwa zaidi na teknolojia ya betri na hali ya joto ya mazingira ya kazi ya dhoruba-kwa ujumla, joto la juu la mazingira, chini ya ufanisi wa malipo.

Inaathiriwa zaidi na kiwango cha kutokwa, joto la kawaida, upinzani wa ndani, na mambo mengine. Kwa ujumla, kiwango cha juu cha kutokwa, kiwango cha juu cha kutokwa. Chini ya ufanisi wa kutokwa. Ya chini ya joto, chini ya ufanisi wa kutokwa.

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.

Upinzani tuli wa ndani ni upinzani wa ndani wa betri wakati wa kutoa, na upinzani wa ndani wenye nguvu ni upinzani wa ndani wa betri wakati wa kuchaji.

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.

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.

Ikiwa unachanganya betri mpya na za zamani na uwezo tofauti au kuzitumia pamoja, kunaweza kuvuja, voltage ya sifuri, nk. Hii ni kutokana na tofauti ya nguvu wakati wa mchakato wa malipo, ambayo husababisha baadhi ya betri kuwa na chaji zaidi wakati wa malipo. Betri zingine hazijachajiwa kikamilifu na zina uwezo wakati wa kutokwa. Betri ya juu haijachajiwa kikamilifu, na betri yenye uwezo wa chini imetolewa zaidi. Katika mzunguko huo mbaya, betri imeharibiwa, na inavuja au ina voltage ya chini (sifuri).

Kuunganisha ncha mbili za nje za betri kwa kondakta yoyote itasababisha mzunguko mfupi wa nje. Kozi fupi inaweza kuleta madhara makubwa kwa aina tofauti za betri, kama vile ongezeko la joto la elektroliti, shinikizo la hewa la ndani, n.k. Ikiwa shinikizo la hewa litazidi voltage ya kuhimili ya kifuniko cha betri, betri itavuja. Hali hii inaharibu sana betri. Valve ya usalama ikishindwa, inaweza kusababisha mlipuko. Kwa hiyo, usifanye mzunguko mfupi wa betri nje.

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.

Ikiwa haitatumia kifaa cha umeme kwa muda mrefu, ni bora kuondoa betri na kuiweka kwenye joto la chini, mahali pa kavu. Ikiwa sivyo, hata ikiwa kifaa cha umeme kimezimwa, mfumo bado utafanya betri kuwa na pato la chini la sasa, ambalo litafupisha Maisha ya huduma ya dhoruba.

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).
