Iimoto zombane ezizayo ziya kukhululeka nge-cobalt.UJan Woitas / umanyano lomfanekiso ngokusebenzisa imifanekiso kaGetty I-Cobalt, ityuwa ebiza kakhulu, enqabileyo nenetyhefu ebisetyenziselwa ukwenza yonke into ye-cathode yeebhetri ze-lithium-ion, iya kuthi shwaka ngokuthe ngcembe kwizithuthi zombane ezizayo, zingazenzi ukuba zingabi yingozi kwezendalo kuphela, kodwa zitshiphu. Lowo ngumfanekiso opeyintwe ngabenzi beebhetri abakhulu be-EV kwihlabathi kulo nyaka Umboniso wezoMbane zabaThengi (i-CES) .
IPanasonic, umboneleli omkhulu webhetri kuTesla, ityhile iiseli zayo ezintsha ze-lithium-ion eziqukethe ngaphantsi kweepesenti ezi-5 ze-cobalt. Inkampani yaseJapan iceba ukuqhubela phambili ukunciphisa ipesenti iye kwi-zero kwiminyaka emibini ukuya kwemithathu ezayo, ecela umngeni kumbono wokuvelisa kodwa kufanelekile kumzamo wezizathu zoqoqosho nezokusingqongileyo.
Ukunciphisa i-cobalt kwenza kube nzima kuthi ukuvelisa, kodwa ekugqibeleni kunciphisa ifuthe elibi lokusingqongileyo kweebhetri kunye nokunciphisa iindleko, utshilo uCelina Mikolajczak, usekela mongameli wetekhnoloji yebhetri ePanasonic Energy yaseNyakatho Melika.
Iibhetri zihlala zibala iipesenti ezingama-30 ukuya kuma-40 eepesenti zeendleko zesithuthi sombane, kwaye icobalt yenye yezona zinto zibiza kakhulu kwinkqubo yokuvelisa. Ngokususa i-cobalt, abenzi be-EV baya kuba nakho ukunciphisa iindleko kunye nexabiso leemoto zombane ukuya kuthi ga kwisithathu.
Kwiminyaka emibini okanye emithathu ukusukela ngoku, siya kuba nakho ukwazisa nge-cobalt-free, cell-density cell, uShawn Watanabe, intloko yezobuchwephesha yamandla kunye nemveliso yePanasonic, utshilo uLwesithathu ngexesha leseshoni ekwi-Intanethi e-CES.
Bona kwakho: U-Elon Musk utyhila ukuTshintsha kweBhetri yeTekhnoloji eTesla 'Usuku lweBhetri'
Ezi bhetri zePanasonic ziya kunika amandla isizukulwana esilandelayo seemoto zeTesla njengoko umenzi we-EV ephuhlisa iibhetri zayo ezingenacobalt.
Ngo-Septemba ophelileyo, u-CEO we-Tesla u-Elon Musk wabhengeza izicwangciso zokukhupha i-25,000 yemoto yombane kwiminyaka emithathu ngokwenza imveliso ngobuninzi. Ubungakanani bendlu ebhetri ebizwa ngokuba yi-4680. Kude kube lelo xesha, iTesla Model Y kunye neModeli 3 ziya kuqhubeka zisebenzisa iiseli zePanasonic ezingama-2170. NgoJuni ophelileyo, ezi nkampani zimbini zatyikitya isivumelwano seminyaka emithathu sokwenza iibhetri kumzi mveliso weTesla's Nevada. Kwaye ngoJanuwari, uTesla watyikitya isivumelwano sePanasonic yokubonelela ngeebhetri ngqo kwisityalo sayo saseJapan.
Kwakhona e-CES, iGeneral Motors ibonise inkqubo yayo entsha yebhetri ye-Ultium ephuhliswe ngentsebenziswano nomthengisi weTesla, uLG. I-Ultium sisakhiwo seebhetri esineemodyuli esisebenzisa iipesenti ezingama-70 ezingaphantsi kwe-cobalt ngokutshintsha into nge-aluminium kwikhemistri yebhetri.
Iibhetri ze-Ultium ziya kunika amandla iimodeli ezingama-30 ezintsha ze-GM ngo-2025, kubandakanya i-hyped GMC Hummer EV kunye neCadillac Lyriq, utshilo uDoug Parks, usekela-mongameli olawulayo we-GM kuphuhliso lweemveliso zehlabathi.
