Batire ya Lithium (Li-ion, Batire ya Lithium Ion)Mabatire a lithiamu-ion ali ndi ubwino wolemera pang'ono, mphamvu zambiri, komanso osakumbukira, motero amagwiritsidwa ntchito kwambiri - zida zambiri zama digito zimagwiritsa ntchito mabatire a lithiamu-ion ngati gwero lamagetsi, ngakhale kuti ndi okwera mtengo kwambiri. Mphamvu ya mabatire a lithiamu-ion ndi yokwera kwambiri, ndipo mphamvu yake ndi yowirikiza ka 1.5 mpaka 2 kuposa yaMabatire a NiMHali ndi kulemera komweko, ndipo ali ndi mphamvu yotsika kwambiri yotulutsa madzi okha. Kuphatikiza apo, mabatire a lithiamu-ion alibe "kukumbukira" konse ndipo alibe zinthu zapoizoni ndipo ubwino wina ndi chifukwa chofunikira chogwiritsidwa ntchito kwambiri. Dziwaninso kuti mabatire a lithiamu nthawi zambiri amakhala ndi batire ya lithiamu ya 4.2V kapena batire yachiwiri ya lithiamu ya 4.2V kapena batire yotha kubwezeretsanso ya lithiamu ya 4.2V kunja.

Batri ya lithiamu ya 18650
18650 ndiye amene anayambitsa batire ya lithiamu-ion – ndi batire ya lithiamu-ion yokhazikika yomwe idakhazikitsidwa ndi kampani ya ku Japan ya SONY kuti tisunge ndalama, 18 imatanthauza m'mimba mwake wa 18mm, 65 imatanthauza kutalika kwa 65mm, 0 imatanthauza batire yozungulira. 18650 imatanthauza, m'mimba mwake wa 18mm, 65mm kutalika. Ndipo nambala ya batire ya nambala 5 ndi 14500, m'mimba mwake wa 14 mm ndi 50 mm kutalika. Batire ya 18650 imagwiritsidwa ntchito kwambiri m'mafakitale, ntchito za anthu wamba ndizochepa kwambiri, zomwe zimagwiritsidwa ntchito kwambiri m'mabatire a laputopu ndi ma tochi apamwamba.

Mabatire wamba a 18650 amagawidwa m'mabatire a lithiamu-ion, mabatire a lithiamu iron phosphate. Voltage ya batri ya lithiamu-ion ya voteji yodziwika ya 3.7v, voteji yodulidwa yochajira ya 4.2v, voteji yodulidwa yochajira ya lithiamu iron phosphate ya 3.2V, voteji yodulidwa yochajira ya 3.6v, mphamvu nthawi zambiri imakhala 1200mAh-3350mAh, mphamvu yodziwika ndi 2200mAh-2600mAh. 18650 lithiamu batri ya moyo wa moyo wa nthawi yozungulira yochajira nthawi 1000.

Batire ya 18650 Li-ion imagwiritsidwa ntchito kwambiri m'mabatire a laputopu chifukwa cha mphamvu yake yayikulu pa unit density. Kuphatikiza apo, batire ya 18650 Li-ion imagwiritsidwa ntchito kwambiri m'magawo amagetsi chifukwa cha kukhazikika kwake bwino pantchito: imagwiritsidwa ntchito kwambiri mu tochi yapamwamba, magetsi onyamulika, chotumizira deta chopanda zingwe, zovala ndi nsapato zofunda zamagetsi, zida zonyamulika, zida zonyamulika, chosindikizira chonyamulika, zida zamafakitale, zida zamankhwala, ndi zina zotero.

Batire ya Li-ion yolembedwa 3.7V kapena 4.2V ndi yofanana. 3.7V imatanthauza voteji ya nsanja (monga, voteji yachizolowezi) panthawi yogwiritsa ntchito batire yotulutsa, pomwe ma volts 4.2 amatanthauza voteji ikadzachajidwa yonse. Batire ya lithiamu ya 18650 yomwe ingadzachajidwenso, voteji imalembedwa 3.6 kapena 3.7v, 4.2v ikadzachajidwa yonse, zomwe sizikugwirizana kwenikweni ndi mphamvu (mphamvu), mphamvu ya batire ya 18650 kuyambira 1800mAh mpaka 2600mAh, (mphamvu ya batire ya 18650 makamaka imakhala mu 2200 ~ 2600mAh), mphamvu ya batire ya 3500 kapena 4000mAh kapena kuposerapo ilipo.

Kawirikawiri amakhulupirira kuti mphamvu ya batri ya Li-ion yopanda katundu idzakhala pansi pa 3.0V ndipo magetsi adzagwiritsidwa ntchito (mtengo wake uyenera kudalira mtengo woyambira wa bolodi loteteza batri, mwachitsanzo, pali otsika ngati 2.8V, palinso 3.2V). Mabatire ambiri a lithiamu sangatulutsidwe ku mphamvu ya 3.2V kapena kuchepera, apo ayi kutulutsa kwambiri kudzawononga batri (mabatire a lithiamu amsika amagwiritsidwa ntchito ndi mbale yotetezera, kotero kutulutsa kwambiri kudzapangitsanso kuti mbale yotetezera isazindikire batri, motero sangathe kuyichaja batri). 4.2V ndiye malire apamwamba a mphamvu ya batri yochaja, yomwe nthawi zambiri imawonedwa ngati mphamvu ya mabatire a lithiamu yopanda katundu yomwe imachajidwa ku 4.2V pamagetsi. Zonse, njira yochaja batri, mphamvu ya batri pa 3.7V imakwera pang'onopang'ono kufika pa 4.2V, kuyachaja batri ya lithiamu sikungatulutsidwe ku mphamvu ya 4.2V yopanda katundu, apo ayi idzawononganso batri, komwe ndi malo apadera a mabatire a lithiamu.

Ubwino

1. Mphamvu yayikulu ya batire ya lithiamu 18650 nthawi zambiri imakhala pakati pa 1200mah ~ 3600mah, pomwe mphamvu yonse ya batire ndi pafupifupi 800mah, ngati iphatikizidwa mu paketi ya batire ya lithiamu 18650, paketi ya batire ya lithiamu 18650 ikhoza kuswa 5000mah.

2. Moyo wautali wa batri ya lithiamu 18650 ndi wautali kwambiri, kugwiritsa ntchito kwabwinobwino kwa moyo wa batri mpaka nthawi 500, ndikoposa kawiri batri wamba.

3. Chitetezo chapamwamba cha batire ya lithiamu 18650, kuti batire isagwe chifukwa cha kufupika kwa nthawi ya batire, mabatire a lithiamu 18650 okhala ndi ma poles abwino ndi oipa amalekanitsidwa. Chifukwa chake kuthekera kwa kufupika kwa nthawi ya batire kwachepetsedwa kwambiri. Mutha kuwonjezera mbale yotetezera kuti mupewe kudzaza batire mopitirira muyeso komanso mopitirira muyeso, zomwe zingawonjezere moyo wa batire.

4. Voliyumu yayikulu ya batire ya lithiamu 18650 nthawi zambiri imakhala pa 3.6V, 3.8V ndi 4.2V, yokwera kwambiri kuposa voliyumu ya 1.2V ya mabatire a NiCd ndi NiMH.

5. Palibe vuto la kukumbukira Palibe chifukwa chochotsera mphamvu yotsalayo musanayiyike, ndikosavuta kugwiritsa ntchito.

6. Kukana pang'ono kwamkati: Kukana kwamkati kwa maselo a polima ndi kochepa kuposa kwa maselo amadzimadzi wamba, ndipo kukana kwamkati kwa maselo a polima am'nyumba kumatha kukhala kochepera 35mΩ, zomwe zimachepetsa kwambiri kugwiritsa ntchito batri ndikuwonjezera nthawi yoyimirira ya mafoni am'manja, ndipo zimatha kufikira kwathunthu mulingo wapadziko lonse lapansi. Mtundu uwu wa batri ya lithiamu ya polima yomwe imathandizira kutulutsa mphamvu yayikulu ndi yoyenera mitundu yowongolera kutali, kukhala njira ina yabwino kwambiri m'malo mwa mabatire a NiMH.
