Wide-kutentha lithiamu batireNthawi zambiri amatanthauza mabatire a lithiamu-ion kutentha kwambiri, ndiye ngati kuphulika kumachitika pakagwiritsidwa ntchito, kumakhala ndi zotsatira zotani pa batire?Tikudziwa kuti batire cell nthawi zambiri ternary lithiamu batire.Ndipo tsopano pali maselo osiyanasiyana, monga ena mwa wamba ternary mabatire lifiyamu ntchito graphite zoipa elekitirodi, mtundu wa zinthu kwa elekitirodi zoipa, mabatire lifiyamu pulayimale ntchito lifiyamu cobaltate zakuthupi kwa elekitirodi zabwino.Kotero kutentha kwakukulu kwa lithiamu batire idzaphulika pansi pa kutentha kwakukulu?Pano kugawana nanu malingaliro oyenera.
Monga zipangizo zomwe zimagwiritsidwa ntchito m'maselo a batri omwe alipo, kuphatikizapo mabatire a ternary lithiamu-ion ndi lithiamu cobaltate, lithiamu iron phosphate ndi zipangizo zina zopangira electrode yabwino.Choncho ternary lithiamu batire mu kutentha otsika pamene Mwina kuphulika ndi kochepa kwambiri.Koma ambiri msika wamakono kutentha lonse lithiamu mabatire ntchito lithiamu cobaltate monga elekitirodi zabwino.Ndipo lifiyamu chitsulo mankwala zachokera ternary lithiamu kuchita elekitirodi zoipa;ndi lithiamu cobaltate ndi kupanga electrode zabwino;ndi ternary lithiamu ion ndikuchita electrode negative osati electrode positive.Izi zimabweretsa kusintha kwa batri yake.
Kuti athetse vuto lachitetezo cha mabatire a lithiamu kutentha kwakukulu, chofunikira ndikuwongolera chitetezo.Choyamba, batire selo ayenera mosamalitsa ankalamulira, amenenso ndi chitsimikizo cha ntchito batire ndi bwino kupewa mkati yochepa dera kapena overcharge pa ntchito batire, komanso kupewa kupezeka kwa mkulu kutentha mkati batire. , zomwe zimayambitsa kuphulika kwa batri.Ndipo pakugwiritsa ntchito tsiku ndi tsiku muyenera kulabadiranso moyo wotetezeka wa batri ndikupewa kutenthedwa kwa batri, kuchulukirachulukira ndi zina.Kenako, tiyenera kulabadira mmene kutentha pa batire.Kutentha kwa batri ndikokwera kwambiri kuti chitetezo chathu chamoyo chikhale chowopsa.Chifukwa chake, ngati zinthu za batri zikufuna kugwiritsidwa ntchito bwino pamoyo wathu watsiku ndi tsiku, tiyeneranso kulabadira ntchito yowongolera kutentha kwa batri.
Kuchokera kumalo otetezedwa, pamene kutentha kwa batri ndipamwamba kwambiri, mabatire a lithiamu-ion atha kuchitika chodabwitsa choyaka moto.Izi ndichifukwa choti lifiyamu ion yomwe ili mu batire ya lithiamu-ion imapangidwa makamaka ndi madontho amadzimadzi, madontho amadzimadzi kwambiri, kutentha kwa batire ya lithiamu-ion, ngati lithiamu-ion mu electrolyte kusamuka kwakukulu, kufalikira kumapangitsa Lifiyamu ion zosasinthika kusamuka kumabweretsa batire yochepa dera mowiriza kuyaka, etc. batire moto kapena kuphulika.Choncho, poyang'ana chitetezo, kugwiritsa ntchito mabatire a lithiamu-ion kutentha kwakukulu kuyenera kuzimitsidwa panthawi yake.Kuonjezera apo, ngati kutentha kuli kwakukulu kwambiri, n'zosavuta kuyambitsa kufupikitsa kwapakati mkati ndipo motero kumayambitsa moto ndi kuphulika.Kuonjezera apo, kuchokera kumalo otetezeka a batri yamagetsi, ngati sikuyang'anitsitsa chitetezo chokwanira komanso kugwiritsa ntchito kutentha kwamphamvu kwa batri ya lithiamu-ion ikhoza kuphulika.
M'malo mwake, batire yayikulu ya lithiamu ndi yotetezeka kugwiritsa ntchito chifukwa imakwaniritsa zofunikira zachitetezo cha mabatire a lithiamu-ion mu GB18483-2001 Safety Technical Specification for Lithium-ion Batteries, yomwe imagwirizana kwambiri ndi miyezo yachitetezo.Koma chifukwa ndi chinthu chatsopano, palibe mfundo zomveka bwino za dziko ndi makampani omwe amatsogolera chitukuko cha teknolojiyi, choncho tiyenera kuphatikiza kugwiritsa ntchito kumvetsetsa kwapadera.Mu ntchito ndondomeko ayenera kupewa kukhudzana ndi kutentha, malo amodzi magetsi, pa kumaliseche, kumaliseche ndi zinthu zina zoopsa, apo ayi n'zosavuta chifukwa pachimake kuphulika.Choncho ntchito tsiku ndi tsiku ayenera kulabadira ntchito otetezeka lonse kutentha lithiamu mabatire komanso yosungirako otetezeka ndi ntchito.
The pamwamba ndi za ngati lonse kutentha lifiyamu batire kuphulika ndi lonse kutentha lifiyamu batire zokhudzana okhutira.
