Bafuputsi ba thehile mokhoa oa ho sebelisa lintho hape o ka khutlisang 100% ea aluminium le 98% ea lithium libetering tsa likoloi tsa motlakase.
Bafuputsi ba Sweden ba re ba thehile mokhoa o mocha, o sebetsang hantle haholoanyane oa ho sebelisa libeteri tsa likoloi tsa motlakase hape.
“Kaha mokhoa ona o ka atolosoa, re tšepa hore o tla sebelisoa indastering lilemong tse tlang,” ho boletse moetapele oa thuto Martina Petranikova.
Ho hydrometallurgy ea setso, litšepe tsohle tse libetering tsa likoloi tsa motlakase li qhibiliha ka har'a li-acid tse sa pheleng.
"Litšila" tse kang aluminium le koporo lia tlosoa ebe litšepe tsa bohlokoa tse kang cobalt, nickel, manganese le lithium lia fumanoa.
Leha bongata ba aluminium le koporo tse setseng bo le nyane, bo hloka mehato e 'maloa ea tlhoekiso,' me mohato ka mong ts'ebetsong o ka bolela tahlehelo ea lithium.
Bafuputsi Univesithing ea Theknoloji ea Chalmers ea Sweden ba hlahisitse mokhoa oa ho sebelisa lintho hape o ka khutlisang 100% ea aluminium le 98% ea lithium libetering tsa likoloi tsa motlakase.
E kenyelletsa ho fetola tatellano ea hona joale ea lits'ebetso le ho sebetsana haholo-holo le lithium le aluminium.
Ka nako e ts'oanang, tahlehelo ea thepa ea bohlokoa e tala e kang nickel, cobalt le manganese ea fokotseha.
“Ho fihlela joale, ha ho motho ea kileng a khona ho fumana maemo a nepahetseng a ho sebelisa oxalic acid ho arola bongata bo boholo ba lithium ha a ntse a tlosa aluminium eohle ka nako e le 'ngoe,” ho boletse Leah Rouquette, seithuti se fumaneng mangolo Lefapheng la Khemistri le Boenjiniere ba Lik'hemik'hale. Univesithing ea Theknoloji ea Chalmers.
"Kaha libeteri tsohle li na le aluminium, re hloka ho khona ho e tlosa ntle le ho lahleheloa ke litšepe tse ling."
Laboratoring ea bona ea ho sebelisa libeteri hape, Rouquette le moetapele oa lipatlisiso Petranikova ba ile ba beha libeteri tsa likoloi tse sebelisitsoeng le lintho tse silafalitsoeng ka har'a setshelo sa mosi.

Mohato oa ho qetela ts'ebetsong ke ho arola litšepe tsena ho ntša lithium, e ka sebelisoang ho etsa libeteri tse ncha.
“Kaha litšepe tsena li na le thepa e fapaneng haholo, ha re nahane hore ho tla ba thata ho li arola. Mokhoa oa rona ke mokhoa o mocha o tšepisang oa ho sebelisa libeteri hape oo ka sebele o lokelang ho hlahlojoa haholoanyane,” ho boletse Rouquette.
Sehlopha sa bafuputsi sa Petranikova se qetile dilemo tse ngata se etsa dipatlisiso tse nang le boiphihlelo mabapi le ho sebedisa ditshipi hape ka dibeteri tsa lithium-ion.
