Uphuhliso lwamva nje kwi-hybrid solid-liquid kunye neebhetri-eziqinileyo zonke

Iqhutywa yimigaqo-nkqubo, itekhnoloji, kunye nemfuno, imakethi yebhetri yelizwe eliqinileyo ifumene umfutho othe kratya kwaye yakhawulezisa inkqubo yayo yoshishino kulo nyaka. I-electrolyte eqinileyo ye-Sulfide ifikelele kwinqanaba lokuguquka kwezoshishino, kunye nokuvela kweemfuno ezahlukeneyo zezicelo kwiindawo ze-niche ezifana ne-eVTOL. Uphuhliso lulonke lweebhetri zombuso oqinileyo lukhawulezisa utshintsho ukusuka kuphando ukuya kwiziphumo zoshishino. Ukuqinisekiswa kobuNjineli kuye kwaqhubela phambili uphuhliso nokuphunyezwa kweenkqubo ezintsha nezixhobo. Uphuhliso lwangoku lweebhetri zombuso oqinileyo luvelise izinto ezininzi ezintsha.

Kwinqanaba langoku, iibhetri ezilulwelo oluxutyiweyo kunye neebhetri ezikwimeko eqinileyo ziphuhla ngokunxuseneyo, ezinokhuphiswano olukhulayo lomhlaba.

Imfuno eyohlukeneyo iyavela, ibangela i-hybride eqinileyo-elulwelo kunye neebhetri ezikwimeko yonke.

Ukusuka kumbono wemarike, ii-automakers zasekhaya kunye nezamazwe ngamazwe ngaphambili zazijongwa njengezona mpembelelo ziphambili eziqhuba ukuthunyelwa kwangaphambili kunye nenkqubela phambili yeebhetri zombuso oqinileyo, kunye nezithuthi zamandla amatsha (NEVs) zibonwa njengemeko yokuqala yokusetyenziswa kwezi bhetri. E-China, iibhetri ze-hybrid solid-liquid sele zifakwe kwizithuthi kulo nyaka.

Ekupheleni kuka-2023, i-NIO, ngokubambisana ne-WeLion New Energy, yazisa imveliso yokuqala yebhetri eyomeleleyo yolwelo oluxutyiweyo. Ibhetri ifumene ubuninzi bamandla obuyi-360 Wh/kg kwaye yayilwa ngesistim ye-150 kWh, exhasa umgama we-1,000 km, nto leyo ephawula isiganeko esibalulekileyo kushishino lweebhetri zombuso oqinileyo.

Ukusukela ekuqaleni kwalo nyaka, iibhetri ze-hybrid solid-liquid ezikhokelwa yi-WeLion New Energy sele ziqalile ukuthumela, kunye nofakelo olongezelelekileyo oludlula i-2.6 GWh ngoJulayi. Ngo-Agasti, i-SES AI ye-100 Ah i-hybrid solid-liquid lithium-metal cell iphumelele uvavanyo lokhuseleko lwe-GB 38031-2020: IiMfuno zoKhuseleko kwiiBattery zeTraction yezithuthi zoMbane, ibe yiseli yokuqala ye-lithium-metal kwishishini ukuhlangabezana nalo mgangatho. Urhwebo lweemveliso zebhetri ezilulwelo oluxutyiweyo olusuka kuqaliso lwetekhnoloji nalo luyakhawuleza.

Olu phuhliso lubonisa ukuba iibhetri ze-hybrid solid-liquid zifikelela ekukhuleni okwandayo kwitekhnoloji, iinkqubo zokuvelisa, kunye nosetyenziso olukhulu, ngelixa zifumana ukuqondwa okukhulayo kwintengiso.
