18650 lithiamu-ion batire kuyitanitsa pa kutentha kochepa kudzakhala ndi zotsatira zotani? Tiyeni tione m'munsimu.
Kodi zotsatira za kulipiritsa 18650 lithiamu-ion batire m'malo otsika kutentha ndi chiyani?
Kulipiritsa mabatire a lithiamu-ion m'malo otentha kumabweretsa ngozi zina. Izi zili choncho chifukwa pamodzi ndi kuchepetsa chinyezi, ndi kinetic katundu wa graphite zoipa elekitirodi patsogolo kuwonongeka kwa nawuza gawo, ndi electrochemical polarization wa elekitirodi negative kwambiri aggravated, mpweya wa lithiamu zitsulo sachedwa mapangidwe lithiamu. dendrites, kulimbikitsa diaphragm ndipo motero kuchititsa kagawo kakang'ono ka maelekitirodi abwino ndi oipa. Momwe ndingathere kuteteza batire ya lithiamu-ion pa kutentha kochepa.
Poganizira kutentha otsika, ndi elekitirodi zoipa pa zisa lifiyamu-ion batire adzaoneka makhiristo ion, akhoza mwachindunji kuboola diaphragm, nthawi yachibadwa zingachititse yaying'ono-yachidule dera zimakhudza moyo ndi ntchito, kwambiri ndi mwina kuphulika!
Malinga ndi kafukufuku wovomerezeka wa akatswiri: mabatire a lithiamu-ion kwa nthawi yochepa m'malo otsika kutentha, kapena kutentha kuli kutali ndi otsika, kumangokhudza kwakanthawi mphamvu ya batri ya mabatire a lithiamu-ion, koma sangabweretse kuwonongeka kosatha. . Koma ngati atagwiritsidwa ntchito kwa nthawi yayitali m'malo otsika kwambiri, kapena -40 ℃ malo otsika kwambiri, mabatire a lithiamu-ion amatha kuzizira kuti awononge kuwonongeka kosatha.
Kugwiritsa ntchito kutentha pang'ono kwa mabatire a lithiamu-ion kumakhala ndi mphamvu yochepa, kuwola kwambiri, kusachita bwino kochulukitsa kachulukidwe, kutchulidwa kwambiri kwa lithiamu, komanso kuyika kwa lithiamu kosakwanira. Komabe, pamodzi ndi kusinthika kosalekeza kwa ntchito zazikuluzikulu, zopinga zomwe zimabweretsedwa ndi kuchepa kwa kutentha kochepa kwa mabatire a lithiamu-ion zikuwonekera kwambiri. Muzamlengalenga zolemetsa, zolemetsa, magalimoto amagetsi ndi magawo ena, batire imafunika kugwira ntchito bwino pa -40 ° C. Chifukwa chake, kuwongolera kosalekeza kwa zinthu zotsika kutentha kwa mabatire a lithiamu-ion kuli ndi tanthauzo laukadaulo.
Kumene,ngati batire yanu ya 18650 ya lithiamu ili ndi zida zotsika kutentha, imatha kuyimbidwa nthawi zonse pamalo otsika kwambiri.
