I-Guoxuan: Sifinyelele ku-0,212 kWh/kg kumaseli ethu e-LFP, siya phambili. Lawa amasayithi e-NCA/NCM!

AmaShayina angamaGuoxuan aziqhayisa ngokuthi ayengene endaweni eyayihlala kuphela amaseli e-lithium-ion anama-cathodes ane-cobalt. Le nkampani ithe ikwazile ukuzuza ukuminyana kwamandla okungaphezu kuka-0,2 kWh / kg kuseli entsha ye-lithium iron phosphate (LFP) ku-sachet.

Amaseli e-LFP - ngolunye usuku "abuthakathaka kakhulu" abe "muhle ngokwanele"

Amaseli e-lithium iron phosphate anezinzuzo eziningi: awasebenzisi i-cobalt, ngakho-ke eshibhile kunamaseli anama-cathodes aqukethe le elementi. Ngaphezu kwalokho, bona ezingashi lapho ilimele futhi imelana izinkulungwane zemijikelezo yokushaja... Futhi bane-drawback eyodwa enkulu: banikeza ukuminyana kwamandla okuphansi kunamaseli e-NCA/NCM ngoba angaphansi kuka-0,2 kWh / kg, kuyilapho i-NCA / NCM yeqe u-0,25 futhi isondela ku-0,3 kWh./kg.

Okungenani bekulokhu kunjalo kuze kube manje.

Inkampani yaseShayina i-Guoxuan, okwamanje ehlinzeka ngamaseli e-LFP emakethe yaseShayina, ibika ukuthi iphumelele ekudaleni amaseli e-lithium iron phosphate kuma-sachets (isithombe) nge-energy density ye-0,212 kWh/kg. Akukapheli, inkampani ifuna ukufinyelela ku-2021 kWh/kg ku-0,23 futhi ifike ku-2022 kWh ngo-0,26, osekuyinani kakade eduze kwamaseli e-NCA/NCM.

Umkhiqizi uphinde aziqhenye ngokusebenzisa ubuchwepheshe be-jelly-roll-to-module, okuyinto, njengoba negama libonisa, ivumela. kusetshenziswa amaqembu amaseli njengamamojula, ngaphandle kwezivalo ezengeziwe. Nokho, isithombe asibonisi ukuthi isixhumanisi sinikeza ithuba elinjalo. Uma kunjalo, kufanele kube nohlobo oluthile lwe "comb", ifreyimu yensimbi exhunywe emaphethelweni amade e-sachet, okungenani sicabanga kanjalo.

Ngeke ubone okufana nalokhu (umthombo):
