Ib qho cais yogib daim nyias nyias muab tso rau ntawm electrodes ntawm opposite polarity, permeable rau ionic txaustab sis tiv thaiv hluav taws xob tiv tauj ntawm cov electrodes. Ntau yam khoom sib cais tau siv rau hauv cov roj teeb ntau xyoo.
Lub hom phiaj ntawm lub tshuab cais hauv lub roj teeb yog dab tsi?
Ib qho tseem ceeb tshaj plaws ntawm tes ua kom muaj kev nyab xeeb ntawm tes yog qhov sib cais, nyias nyias nyias nyias uas lub cev cais cov anode thiab cathode. Lub luag haujlwm tseem ceeb ntawm cov khoom sib cais yog txhawm rau tiv thaiv kev sib cuag ntawm lub cev ntawm anode thiab cathode, thaum ua kom yooj yim thauj ion hauv cell.
Dab tsi yog tus cais hauv lub roj teeb hu ua?
Polymer separators, zoo ib yam li cov roj teeb cais feem ntau, ua raws li cov khoom sib cais ntawm anode thiab cathode hauv Li-ion roj teeb thaum tseem ua rau kev txav ntawm ions los ntawm lub xov tooj ntawm tes..
Vim li cas cais cais siv hauv Li-ion roj teeb?
Sib cais yog ib qho tseem ceeb hauv lub Li-ion roj teeb ntawm tes. Lawv xav tau rau kev sib cais anode thiab cathode nyob rau hauv ib lub cell thaum tso cai rau siab tshaj plaws ionic conductivity ntawm Li ion uas muaj electrolyte.
Yuav ua li cas cais cov roj teeb lithium ion?
Cov khoom siv tshuab ntawm cov khoom sib cais yog li tseem ceeb heev rau kev tswj xyuas kev sib cais thiab Li-ion roj teeb kev nyab xeeb. Polyethylene (PE), polypropylene (PP), thiab PE / PP cais nrog qhov pore qhov ntau thiab tsawgmicrometers tau ua lag luam thiab siv dav hauv Li-ion roj teeb thev naus laus zis [49].
