Abarhubhululi benze indlela yokubuyisela izinto ezisetjenzisiweko engabuyisa i-100% ye-aluminium kanye ne-98% ye-lithium emabhetri weenkoloyi ezisebenzisa igezi.
Abarhubhululi be-Sweden bathi benze indlela etja, esebenzako yokusebenzisa kabutjha amabhetri weenkoloyi ezisebenzisa umtjhini.
"Ngombana indlela le ingakhuliswa, sinethemba lokobana izokusetjenziswa emabubulweni eminyakeni ezako," kutjho umrholi werhubhululo u-Martina Petranikova.
E-hydrometallurgy yendabuko, zoke iinsimbi ezisemabhetri weenkoloyi ezisebenzisa igezi zincibilika ngama-esidi angaphiliko.
”Ukusilaphazeka” okufana ne-aluminium nekhopha kuyasuswa bese kuthi iinsimbi eziqakathekileko ezifana ne-cobalt, nickel, manganese kanye ne-lithium ziyabuyiselwa.
Nanyana inani le-aluminiyamu nethusi eliseleko lincani, litlhoga amagadango amanengi wokuhlanza, begodu igadango ngalinye lendlela lingatjho ukulahlekelwa lithiyamu.
Abarhubhululi be-Sweden's Chalmers University of Technology benze indlela yokubuyisela kabutjha engabuyisa i-100% ye-aluminiyamu kanye ne-98% ye-lithium emabhetri weenkoloyi ezisebenzisa igezi.
Kufaka hlangana ukutjhugulula ukulandelana kweenkambo zamanje begodu khulukhulu ukusetjenziswa kwe-lithium ne-aluminium.
Ngesikhathi esifanako, ukulahlekelwa kwezinto eziqakathekileko ezifana ne-nickel, i-cobalt kanye ne-manganese kuyanciphiswa.
"Bekube nje, akekho umuntu okghone ukuthola ubujamo obufaneleko bokusebenzisa i-oxalic acid ukuhlukanisa inani elikhulu kangaka le-lithium lokha nakususa yoke i-aluminiyamu ngesikhathi sinye," kutjho u-Leah Rouquette, umfundi ophothule eMnyangweni weKhemistri neKhemikhali yobunjiniyela. e-Chalmers University of Technology.
"Njengombana woke amabhetri ane-aluminium, kufuze sikghone ukuyisusa ngaphandle kokulahlekelwa ziinsimbi."
Elebhu yabo yokusebenzisa kabutjha amabhetri, u-Rouquette nomdosiphambili werhubhululo u-Petranikova bafaka amabhetri weenkoloyi asetjenzisiweko kanye nezinto zawo eziphukileko ngaphakathi kwe-fume hood.
Ipuyere emnyama egayiweko incibilika emanzini ahlanzekileko abizwa nge-oxalic acid, isithako esihlaza satjani esitholakala eentjalweni ezifana ne-rhubarb nesipinatjhi.
Faka ipuyere noketshezi emtjhini ofana nomtjhini wokuhlanganisa ekhishini. Lapha, i-aluminium ne-lithium ebhetri zincibilika nge-oxalic acid, kutjhiye iinsimbi eziseleko zisesimeni esiqinileko.
Igadango lokugcina emsebenzini lo kuhlukanisa iinsimbi lezi ukukhipha i-lithium, engasetjenziselwa ukwenza amabhetri amatjha.
"Ngombana iinsimbi lezi zineemfanelo ezihlukileko, asicabangi bona kuzokuba budisi ukuzihlukanisa. Indlela yethu yindlela etja ethembisako yokusebenzisa kabutjha amabhetri okufanele ihlolwe ngokunabileko," kutsho u-Rouquette.
Isiqhema serhubhululo saka-Petranikova sichithe iminyaka senza irhubhululo eliphezulu lokusebenzisa kabutjha iinsimbi emabhetri we-lithium-ion.
Uzibandakanya emaphrojekthini ahlukahlukeneko wokusebenzisana namakhamphani azibandakanya ekusebenziseni kabutjha amabhetri weenkoloyi ezisebenzisa igezi. Isiqhema sisebenzisana namaphrojekthi amakhulu wokurhubhulula nentuthuko begodu imihlobo yaso ifaka hlangana i-Volvo ne-Northvolt.
