Kuwunika Kwa Njira Zamkati Zomwe Zimakhudza Moyo Wa Mabatire a Lithium-ion

Mabatire a lithiamu-ionsinthani mphamvu zamakhemikolo kukhala mphamvu yamagetsi kudzera muzochita zamakina.Mwachidziwitso, zomwe zimachitika mkati mwa batire ndikuchepetsa kwa okosijeni pakati pa ma electrode abwino ndi oipa.Malinga ndi izi, deintercalation ya ion imatha kupanga pano, kotero lithiamu The ion concentration nthawi zambiri sisintha.Komabe, mumayendedwe enieni a batri, kuwonjezera pa zomwe zimachitika mwachizolowezi cha ayoni a lithiamu, machitidwe ambiri am'mbali adzachitika, monga mapangidwe ndi kukula kwa filimu ya SEI, ndi kuwonongeka kwa electrolyte.Zomwe zimachitika zomwe zimatha kutulutsa kapena kudya ma ion a lithiamu zimasokoneza batire yamkati.Pamene malire asinthidwa, adzakhala ndi vuto lalikulu pa batri.Zomwe zili mkati mwa batri zomwe zimayambitsa kuchepa kwa mphamvu ndi moyo wa batri ya lithiamu-ion ndi izi: 1. Kusintha kwa zinthu zabwino za electrode.2. Ma electrolyte amawonongeka.3. Mapangidwe ndi kukula kwa filimu ya SEI.4. Mapangidwe a lithiamu dendrites.5. Mphamvu ya zinthu zosagwira ntchito.

The mkati kulephera limagwirira wamabatire a lithiamunthawi zambiri amayamba chifukwa cha mapangidwe a lithiamu dendrites, kusintha kwa zinthu za cathode ndi kuwonongeka kwa electrolyte.Mwa iwo, mapangidwe a lithiamu dendrites amatha kuyambitsa mabwalo amfupi ndikupangitsa kuthawa kwamafuta.batire cell.Zipangitsa kuti batire liphulike.

Pomaliza, kulephera kwa kafukufuku wamabatire a lithiamu ndikuwerenga njira ndi njira zolepherera batire, kukhathamiritsa batire, ndikuwongolera chitetezo cha batri.Chifukwa chake, kafukufuku wa kulephera kwa batire sangakhale ndi tanthauzo lofunikira pakupanga ndi magwiridwe antchito enieni, komanso ali ndi tanthauzo lofunikira pakuwongolera moyo wa batri, chitetezo ndi kudalirika kwa magalimoto amagetsi, komanso kuchepetsa mtengo wamagalimoto amagetsi.
