Abacwaningi basungule indlela yokuvuselela kabusha engabuyisa u-100% we-aluminium kanye no-98% we-lithium emabhethri ezimoto zikagesi.
Abacwaningi baseSweden bathi basungule indlela entsha nesebenza kahle kakhulu yokuvuselela amabhethri ezimoto zikagesi.
“Ngenxa yokuthi le ndlela ingathuthukiswa, sithemba ukuthi izosetshenziswa embonini eminyakeni ezayo,” kusho umholi wocwaningo uMartina Petranikova.
Ku-hydrometallurgy yendabuko, zonke izinsimbi ezisemabhethrini ezimoto zikagesi zincibilikiswa kuma-asidi angaphili.
"Ukungcola" okufana ne-aluminium nethusi kuyasuswa bese kutholakala izinsimbi eziyigugu ezifana ne-cobalt, i-nickel, i-manganese ne-lithium.
Nakuba inani le-aluminium esele kanye nethusi lincane, lidinga izinyathelo eziningana zokuhlanza, futhi isinyathelo ngasinye kule nqubo singasho ukulahlekelwa yi-lithium.
Abacwaningi eChalmers University of Technology yaseSweden basungule indlela yokusebenzisa kabusha engabuyisa u-100% we-aluminium kanye no-98% we-lithium emabhethri ezimoto zikagesi.
Kuhilela ukushintsha ukulandelana kwamanje kwezinqubo kanye nokucubungula i-lithium ne-aluminium ngokuyinhloko.
Ngesikhathi esifanayo, ukulahlekelwa kwezinto zokusetshenziswa ezibalulekile njenge-nickel, i-cobalt kanye ne-manganese kuncishisiwe.
“Kuze kube manje, akekho oye wakwazi ukuthola izimo ezifanele zokusebenzisa i-oxalic acid ukuhlukanisa inani elikhulu kangaka le-lithium ngenkathi esusa yonke i-aluminium ngesikhathi esisodwa,” kusho uLeah Rouquette, umfundi ophothule eMnyango WezeKhemistri Nobunjiniyela Bekhemikhali eChalmers University of Technology.
"Njengoba wonke amabhethri equkethe i-aluminium, sidinga ukukwazi ukuyisusa ngaphandle kokulahlekelwa ezinye izinsimbi."
Elabhorethri yabo yokuvuselela amabhethri, uRouquette kanye nomholi wocwaningo uPetranikova bafaka amabhethri ezimoto ezisetshenzisiwe kanye nokuqukethwe kwawo okuchotshoziwe endaweni yokushisa umlilo.
Impuphu emnyama egayiwe kahle incibilikiswa kuketshezi olucacile oluphilayo olubizwa ngokuthi i-oxalic acid, isithako esiluhlaza esitholakala ezitshalweni ezifana ne-rhubarb nesipinashi.
Faka ufulawa kanye noketshezi emshinini ofana ne-blender yasekhishini. Lapha, i-aluminium kanye ne-lithium ebhethrini kuncibilikiswa ku-oxalic acid, kushiye izinsimbi ezisele ziqinile.
Isinyathelo sokugcina kule nqubo ukuhlukanisa lezi zinsimbi ukuze kukhishwe i-lithium, engasetshenziswa ukwenza amabhethri amasha.
“Ngenxa yokuthi lezi zinsimbi zinezakhiwo ezihluke kakhulu, asicabangi ukuthi kuzoba nzima ukuzihlukanisa. Indlela yethu iyindlela entsha ethembisayo yokuvuselela amabhethri okufanele nakanjani ihlolwe kabanzi,” kusho uRouquette.
Ithimba locwaningo likaPetranikova lichithe iminyaka liqhuba ucwaningo olusezingeni eliphezulu mayelana nokusetshenziswa kabusha kwezinsimbi kumabhethri e-lithium-ion.
Uhileleke kumaphrojekthi ahlukahlukene okubambisana nezinkampani ezibandakanyeka ekusetshenzisweni kabusha kwamabhethri ezimoto zikagesi. Leli qembu lingumlingani kumaphrojekthi amakhulu ocwaningo nentuthuko kanti izinhlobo zalo zifaka phakathi iVolvo neNorthvolt.
