Batire ya lithiamu-ionkuphulika kumayambitsa:
1. Large mkati polarization;
2. Chidutswacho chimatenga madzi ndikuchitapo kanthu ndi ng'oma ya mpweya wa electrolyte;
3. Ubwino ndi ntchito ya electrolyte yokha;
4. Kuchuluka kwa jakisoni wamadzimadzi sikukwaniritsa zofunikira;
5. Kusasindikiza kosavomerezeka kwa kuwotcherera kwa laser mu ndondomeko ya msonkhano ndi kutuluka kwa mpweya poyesa kutuluka kwa mpweya;
6. Fumbi, fumbi lamtengo wapatali ndilosavuta kutsogolera ku dera laling'ono laling'ono poyamba;
7. Zidutswa zabwino ndi zoipa ndizozikulu kuposa momwe zimakhalira, ndipo ndizovuta kulowa mu chipolopolo;
8. Vuto losindikiza jakisoni wamadzimadzi, magwiridwe antchito achitsulo osindikiza si abwino omwe amatsogolera ku ng'oma yamafuta;
9. Chipolopolo ukubwera chipolopolo khoma makulidwe, chipolopolo mapindikidwe zimakhudza makulidwe;
10. Kunja kwa kutentha kwakukulu kozungulira kumakhalanso chifukwa chofunikira cha kuphulika.
Njira zodzitchinjiriza zotengedwa ndi batri:
Batire ya lithiamu-ionma cell amanyamulidwa kumagetsi apamwamba kuposa 4.2V ndipo ayamba kuwonetsa zotsatira zoyipa.Kukwera kwa voliyumu yowonjezera, m'pamenenso ngoziyo imakwera.Pamene mphamvu ya selo ya lithiamu imakhala yaikulu kuposa 4.2V, osachepera theka la maatomu a lithiamu amakhalabe muzinthu zabwino za electrode, ndipo chipinda chosungiramo zinthu nthawi zambiri chimagwa, zomwe zimapangitsa kuti batire iwonongeke.Ngati kulipiritsa kumapitilizidwa, popeza chipinda chosungiramo ma elekitirodi olakwika chadzaza kale ndi maatomu a lithiamu, chitsulo chotsatira cha lithiamu chidzadziunjikira pamwamba pa zinthu zoyipa zama elekitirodi.Ma atomu a lithiamu awa amakula makristasi a dendritic kuchokera ku anode pamwamba polowera ku ma ion a lithiamu.Izi lithiamu zitsulo makhiristo adzadutsa pepala diaphragm ndi yochepa-dera maelekitirodi zabwino ndi zoipa.Nthawi zina batire imaphulika isanakwane dera lalifupi, izi ndichifukwa chakuchulukirachulukira, ma electrolyte ndi zida zina zimasweka kuti ziwonekere mpweya, kupanga chipolopolo cha batri kapena kuphulika kwa valve kuphulika, kotero kuti mpweya umalowa m'malo ndi kudzikundikira. ma atomu a lithiamu pamwamba pa electrode yoyipa, kenako amaphulika.
Chifukwa chake, polipiramabatire a lithiamu-ion, malire apamwamba amagetsi ayenera kukhazikitsidwa kuti aganizire za moyo, mphamvu, ndi chitetezo cha batri nthawi yomweyo.Malire apamwamba apamwamba a voteji ndi 4.2 V. Payeneranso kukhala malire otsika kwambiri pamene mukutulutsa maselo a lithiamu.Mphamvu yamagetsi ikagwa pansi pa 2.4V, zida zina zimayamba kuwonongedwa.Ndipo chifukwa batire idzadziyimitsa yokha, mukayikanso mphamvu yocheperako, ndiye kuti ndibwino kuti musatulutse 2.4V musanayime.Mphamvu zomwe zimatulutsidwa panthawi ya 3.0V mpaka 2.4V zimangotengera pafupifupi 3% ya mphamvu ya batri ya lithiamu-ion.Chifukwa chake, 3.0V ndi njira yabwino yodulira kuti ichotse.Mukamalipira ndi kutulutsa, kuwonjezera pa kuchepetsa mphamvu yamagetsi, kuchepa kwapano ndikofunikiranso.Pamene panopa ndi okwera kwambiri, ma lithiamu ions alibe nthawi yolowa mu chipinda chosungiramo ndipo adzasonkhanitsa pamwamba pa zinthuzo.
Izilithiamu ionskupeza ma elekitironi ndi crystallize maatomu a lithiamu pamwamba pa zinthu, zomwe ndi zofanana ndi kuchulutsa ndipo zingakhale zoopsa.Pakakhala kuphulika kwa batire, idzaphulika.Choncho, kutetezedwa kwa mabatire a lithiamu-ion kuyenera kuphatikizapo zinthu zitatu: malire apamwamba a magetsi othamanga, malire otsika a magetsi, ndi malire apamwamba a panopa.General lithiamu-ion batire mapaketi, kuwonjezera lithiamu-ion batire maselo, padzakhala mbale zoteteza, mbale zoteteza izi n'kofunika kupereka chitetezo atatu awa.
