Ratidza basa rakakosha re electrolyte mukuvandudza kukurumidza kuchaja kuita kwemabhatiri.

Nhasi, nekuwedzera kukurumbira kwemotokari nyowani dzesimba, huwandu uye kumhanya kwekuchaja kwave kutarisisa kwevatengi zvakanyanya kunetseka. Se "moyo" wemotokari itsva dzemagetsi, mabhatiri e-lithium-ion anotarisa zvakananga huwandu hwemotokari uye kunyatsochaja. Pakati pezvakakosha zvimiro zvelithium-ion mabhatiri, iyo electrolyte inoita basa rakakosha.

I. Kushanda Nheyo yeLithium-ion Mabhatiri uye Kukosha kweElectrolyte

Nheyo yekushanda yemabhatiri e-lithium-ion yakafanana ne "rocking chair". Paunenge uchichaja, lithium ions inoburitswa kubva kune yakanaka electrode, ichipfuura nepamuparadzi, ichienda kune iyo isina kunaka electrode mu electrolyte, uye pakupedzisira inoiswa muiyo yakaipa electrode. Panguva ino, iyo yakaipa electrode inochengetedza simba. Painoburitsa, lithium ions inoburitswa kubva kune negative electrode, dzokera kune yakanaka electrode kuburikidza ne electrolyte, uye kuburitsa simba. Zvinogona kutaurwa kuti electrolyte ndiye mutakuri we reversible migration ye lithium ions pakati pe electrode, uye kushanda kwayo kunobata zvakananga nguva yekuchaja uye yekuburitsa kwebhatiri.

II. Maitiro eElectrolytes Anobata Battery Inokurumidza Kuchaja Performance

Iyo electrolyte chinhu chakakosha mu electrolyte uye inoita basa rakakosha mukukurumidza kuchaja kuita kwebhatiri. Chokutanga pane zvose, ionic conductivity ye electrolyte inobata zvakananga kufamba kwekufamba kwe lithium ions mu electrolyte. Electrolytes ine high ionic conductivity inogona kuita kuti lithium ion ifambe nekukurumidza pakati peyakanaka uye isina kunaka maelectrode, nekudaro ichipfupisa nguva yekuchaja. Semuyenzaniso, mamwe maelectrolyte matsva ane yakakwira ionic mobility uye anogona kupa yakanyatsoshanda ion yekufambisa chiteshi panguva yekuchaja nekukurumidza.

Chechipiri, kugadzikana kwe electrolyte kwakakoshawo pakukurumidza kuchaja kuita. Munguva yekuchaja nekukurumidza, tembiricha yepamusoro uye voltage zvinogadzirwa mukati mebhatiri. Kana iyo electrolyte isina kugadzikana, kuora kana kuita kwedivi kunogona kuitika, zvichikanganisa kushanda uye hupenyu hwebhatiri. Naizvozvo, kusarudza electrolyte nekugadzikana kwakanaka kwakakosha kuti uwane nekukurumidza kuchaja.

III. Zvinhu Zvinokanganisa Kukurumidza Kuchaja Kuita kweElectrolyte

IV. Maitiro ekuvandudza Electrolyte Conductivity

Kuti uvandudze conductivity ye electrolyte, zvinotevera zvinogona kutangwa:

V. Kukosha kweElectrolyte Performance Optimization

Nokuvandudza marudzi ekunyungudutsa, kugadzirisa electrolyte concentration, kuwedzera ion migration number, uye optimizing solvent formulation, kukurumidza kwekufamba kwe lithium ions mu electrolyte kunogona kunyatsowedzerwa, nokudaro kupfupisa nguva yekuchaja. Izvi hazvingogadziri ruzivo rwevashandisi vevatengi, zvinopa huwandu huri nani uye kubhadharisa ruzivo rwekufamba kure-kure kwemotokari dzemagetsi, asi zvakare zvinosimudzira kuvandudzwa kweiyo simba nyowani indasitiri yemotokari.

Mune ramangwana, nekuenderera mberi kwekufambira mberi kwetekinoroji, zvinotendwa kuti kuita kwe electrolyte kuchawedzerwa, kuunza simba rakawanda uye nzira dzekushandisa dziri nyore kumotokari nyowani dzesimba. Ngatitarisirei kubudiriro itsva mukukurumidza kuchaja kuita kwemotokari dzesimba idzva uye kupa zvakawanda kune ramangwana rekufamba kwegirinhi.
