Batri ya Lithium (Li-ion, Lithium Ion Battery): Mabatire a lithiamu-ion ali ndi ubwino wolemera kwambiri, mphamvu zambiri, komanso osakumbukira, ndipo motero amagwiritsidwa ntchito kawirikawiri - zipangizo zambiri zamagetsi zimagwiritsa ntchito mabatire a lithiamu-ion monga mphamvu, ngakhale kuti ndi okwera mtengo. Kuchuluka kwa mphamvu zamabatire a lithiamu-ion ndikwambiri, ndipo mphamvu yake ndi 1.5 mpaka 2 kuposaMabatire a NiMHwa kulemera komweko, ndipo ali ndi mlingo wochepa kwambiri wodzitulutsa. Kuphatikiza apo, mabatire a lithiamu-ion alibe pafupifupi "zotsatira zokumbukira" ndipo alibe zinthu zapoizoni ndi zabwino zina ndizofunikanso chifukwa chofala kwambiri. Chonde dziwani kuti mabatire a lithiamu nthawi zambiri amalembedwa ndi 4.2V lithiumion batire kapena 4.2V lithiamu sekondale batire kapena 4.2V lithiumion rechargeable batire kunja.

18650 lithiamu batire
18650 ndiye woyambitsa batire ya lithiamu-ion - ndi mtundu wa batire wa lithiamu-ion wokhazikitsidwa ndi kampani yaku Japan ya SONY kuti apulumutse ndalama, 18 amatanthauza m'mimba mwake 18mm, 65 amatanthauza kutalika kwa 65mm, 0 amatanthauza batire yacylindrical. 18650 amatanthauza, 18mm m'mimba mwake, 65mm kutalika. Ndipo nambala yachitsanzo ya batire ya 5 ndi 14500, 14 mm m'mimba mwake ndi 50 mm kutalika. Batire ya General 18650 imagwiritsidwa ntchito kwambiri m'makampani, kugwiritsidwa ntchito kwa anthu wamba ndikochepa kwambiri, komwe kumagwiritsidwa ntchito kwambiri pamabatire a laputopu ndi ma tochi apamwamba.

Mabatire wamba 18650 amagawidwa kukhala mabatire a lithiamu-ion, mabatire a lithiamu iron phosphate. Lifiyamu-ion batire voteji kwa voteji mwadzina 3.7v, kulipiritsa odulidwa voteji 4.2v, lithiamu chitsulo mankwala batire mwadzina voteji 3.2V, nawuza odulidwa voteji wa 3.6v, mphamvu zambiri 1200mAh-3350mAh, mphamvu wamba ndi 2200mAh-2600mAh. 18650 Lifiyamu moyo wa batire chiphunzitso cha kuzungulira kulipiritsa nthawi 1000.

Batire ya 18650 Li-ion imagwiritsidwa ntchito kwambiri pamabatire a laputopu chifukwa cha kuchuluka kwake pamayunitsi. Kuphatikiza apo, batire ya 18650 Li-ion imagwiritsidwa ntchito kwambiri pamagetsi chifukwa chakukhazikika kwake pantchito: yomwe imagwiritsidwa ntchito kwambiri mu tochi yapamwamba kwambiri, magetsi onyamula, ma transmitter opanda zingwe, zovala zotentha zamagetsi ndi nsapato, zida zonyamula, zida zoyatsira. , chosindikizira chonyamula, zida zamakampani, zida zamankhwala, ndi zina zambiri zida zamankhwala, ndi zina.

Batire ya Li-ion yolembedwa 3.7V kapena 4.2V ndiyofanana. 3.7V imatanthawuza voteji ya papulatifomu (ie, voteji wamba) panthawi yomwe batire imatulutsa, pomwe 4.2 volts imatanthawuza mphamvu yamagetsi poyitanitsa zonse. Wamba rechargeable 18650 lifiyamu batire, voteji ndi chizindikiro 3.6 kapena 3.7v, 4.2v pamene mokwanira ankaperekeza, amene alibe chochita ndi mphamvu (mphamvu), 18650 batire mainstream mphamvu kuchokera 1800mAh kuti 2600mAh, (18650 mphamvu batire mphamvu zambiri mu 2200 ~ 2600mAh), mphamvu yayikulu imalembedwanso 3500 kapena 4000mAh kapena kupitilira apo.

Nthawi zambiri amakhulupirira kuti voteji yopanda katundu wa batri ya Li-ion idzakhala pansi pa 3.0V ndipo magetsi adzagwiritsidwa ntchito (mtengo wake uyenera kudalira mtengo wachitetezo cha batire, mwachitsanzo, pali otsika ngati 2.8V, palinso 3.2V). Mabatire ambiri a lifiyamu sangathe kutulutsidwa ku voteji yopanda katundu wa 3.2V kapena kuchepera, apo ayi kutulutsa kopitilira muyeso kungawononge batire (msika wamba mabatire a lithiamu amagwiritsidwa ntchito ndi mbale yodzitchinjiriza, kotero kukhetsa kwakukulu kudzatsogoleranso mbale yoteteza. sindingathe kuzindikira batire, motero simungathe kulipiritsa batire). 4.2V ndi malire pazipita batire kulipiritsa voteji, ambiri amaona kuti palibe katundu voteji wa lithiamu mabatire mlandu kwa 4.2V pa magetsi Full, batire nawuza ndondomeko, batire voteji pa 3.7V pang'onopang'ono kukwera kwa 4.2V, lithiamu Kulipiritsa kwa batire sikungaperekedwe kupitilira 4.2V osanyamula voliyumu, apo ayi kuwononganso batire, yomwe ndi malo apadera a mabatire a lithiamu.

Ubwino wake

1. Large mphamvu 18650 lifiyamu batire mphamvu zambiri pakati 1200mah ~ 3600mah, pamene mphamvu ambiri batire ndi za 800mah, ngati pamodzi 18650 lifiyamu batire paketi, kuti 18650 lifiyamu batire paketi mwachisawawa akhoza kudutsa 5000mah.

2. Moyo wautali wa 18650 lifiyamu moyo wa batri ndi wautali kwambiri, kugwiritsidwa ntchito kwanthawi zonse kwa moyo wozungulira mpaka nthawi za 500, ndikoposa kawiri batire wamba.

3. High chitetezo ntchito 18650 lithiamu batire chitetezo ntchito, pofuna kuteteza batire yochepa dera chodabwitsa, 18650 lithiamu batire zabwino ndi mizati zoipa analekanitsidwa. Kotero kuthekera kwafupipafupi kwafupika kwachepetsedwa kwambiri. Mutha kuwonjezera mbale yodzitchinjiriza kuti mupewe kulipiritsa komanso kutulutsa batire mochulukira, zomwe zitha kuwonjezeranso moyo wantchito wa batri.

4. High voteji 18650 lithiamu batire voteji zambiri pa 3.6V, 3.8V ndi 4.2V, apamwamba kwambiri kuposa 1.2V voteji wa NiCd ndi NiMH mabatire.

5. Palibe kukumbukira kukumbukira Palibe chifukwa chochotsera mphamvu yotsala musanayipire, yosavuta kugwiritsa ntchito.

6. Small mkati kukana: The kukana mkati mwa maselo polima ndi ang'onoang'ono kuposa maselo ambiri madzi, ndi kukana mkati mwa maselo zoweta polima akhoza ngakhale zosakwana 35mΩ, amene amachepetsa kwambiri batire kudzigwiritsa ntchito ndi kumawonjezera nthawi standby. mafoni am'manja, ndipo amatha kufika pamlingo wapadziko lonse lapansi. Mtundu uwu wa batire ya polima lifiyamu yomwe imathandizira kutulutsa kwakukulu kwaposachedwa ndi yabwino kwamitundu yowongolera kutali, kukhala njira yabwino kwambiri yopangira mabatire a NiMH.
