Uyini Umehluko Phakathi Kwebhethri Le-Lithium Ye-All-Solid-State Nebhethri Le-Lithium Yesifunda Esiqinile?

Amabhethri aqinile akuwona wonke ama-electrolyte aqinile, amanye awuketshezi (ingxube yoketshezi nokuqinile incike esilinganisweni sokuxuba).

Ibhethri le-lithium lesimo esiqinile ibhethri le-lithium eliqinile kodwa elingenawo noma iyiphi i-electrode yesimo esiwuketshezi nezinto ze-electrolyte ngaphansi kwesikhawu sezinga lokushisa elisebenzayo, ngakho igama layo eligcwele ibhethri le-electrolyte lithium eliqinile.

Ibhethri ye-lithium ion yangempela eqinile ine-electrolyte eqinile, kodwa kusekhona i-electrolyte encane ewuketshezi. I-electrolyte yesimo esiqinile ehlanganisa ingxenye ye-electrolyte eqinile, ingxenye ye-electrolyte enguketshezi, noma ingxenye yebhethri iyisimo esiqinile, ingxenye yayo iyisimo soketshezi. Kusenebhethri ye-lithium ion eqinile equkethe ikakhulukazi isimo esiqinile nesimo soketshezi esincane.

Ngokuqondene nebhethri ye-lithium ion yesimo esiqinile ekhaya naphesheya, idumile ngokuqhubekayo. I-America, i-Europe, i-Japan, i-Korea ne-China zonke zitshala kuyo ngezinhloso ezahlukene. Isibonelo, iMelika itshala kakhulu ezinkampanini ezincane neziqalo. Kuneziqalo ezimbili zezempilo eMelika, enye yazo i-S-akit3. Yize isesigabeni sokuqala, ibanga lokushayela lingafinyelela ku-500km.

I-America igxile kubuchwepheshe obuphazamisayo ezinkampanini ezincane kanye neziqalo, kuyilapho iJapane ijwayele ukucwaninga ibhethri ye-lithium ion yesimo esiqinile. Inkampani edume kakhulu eJapan yiToyota, ezokwazi ukuhweba ngo-2022. Okukhiqizwa yiToyota akulona ibhethri ye-lithium ion yonke yesimo esiqinile, kodwa ibhethri ye-lithium ion yesimo esiqinile.

Ibhethri lesimo esiqinile elikhiqizwe iToyota line-graphic, i-sulphide electrolyte njengezinto ze-cathode kanye ne-anode ephezulu ye-voltage. Umthamo webhethri elilodwa ngu-15 Ah, futhi i-voltage ingama-volts amaningi. Kungenzeka ukwenza ukuhweba ngo-2022.

Ngakho i-Japan ayinikeli kubuchwepheshe obuphazamisayo, kodwa isebenzisa i-anode yangaphambili ne-cathode kubhethri ye-lithium ion. IKorea ifana neJapane, ine-graphite cathode kodwa hhayi i-lithium yensimbi. Eqinisweni, kanjalo neChina. Ngenxa yokuthi sesivele sinomugqa omkhulu wokukhiqiza kubhethri ye-lithium ion, asikho isidingo sokuqala kabusha konke ndawonye.
