Abaphandi baye baphuhlisa indlela yokuphinda kusetyenziswe izinto ezinokubuyisa i-100% ye-aluminiyam kunye ne-98% ye-lithium kwiibhetri zezithuthi zombane.
Abaphandi baseSweden bathi baphuhlise indlela entsha nesebenzayo yokuphinda kusetyenziswe iibhetri zezithuthi zombane.
“Ngenxa yokuba le ndlela inokwandiswa, sinethemba lokuba iza kusetyenziswa kushishino kwiminyaka ezayo,” utshilo inkokeli yophando uMartina Petranikova.
Kwi-hydrometallurgy yendabuko, zonke iintsimbi ezikwiibhetri zezithuthi zombane zinyibilika kwii-asidi ezingaphiliyo.
Emva koko "izinto ezingcolileyo" ezifana ne-aluminium kunye ne-copper ziyasuswa kwaye kufunyenwe iintsimbi ezixabisekileyo ezifana ne-cobalt, i-nickel, i-manganese kunye ne-lithium.
Nangona ubungakanani be-aluminium eseleyo kunye nobhedu buncinci, bufuna amanyathelo aliqela okucoca, kwaye inyathelo ngalinye kwinkqubo linokuthetha ukulahleka kwe-lithium.
Abaphandi kwiYunivesithi yeTekhnoloji yaseChalmers eSweden baphuhlise indlela yokuphinda kusetyenziswe izinto ezinokubuyisa i-100% ye-aluminiyam kunye ne-98% ye-lithium kwiibhetri zezithuthi zombane.
Kubandakanya ukutshintsha ulandelelwano lwangoku lweenkqubo kwaye ngokuyintloko kusetyenzwa i-lithium kunye ne-aluminium.
Kwangaxeshanye, ukulahleka kwezinto ezixabisekileyo ezifana ne-nickel, i-cobalt kunye ne-manganese kuyancitshiswa.
“Kude kube ngoku, akukho mntu ukwazileyo ukufumana iimeko ezifanelekileyo zokusebenzisa i-oxalic acid ukwahlula inani elikhulu kangaka le-lithium ngelixa esusa yonke i-aluminium ngaxeshanye,” utshilo uLeah Rouquette, umfundi ophumelele kwiSebe leKhemistri kunye noBunjineli beKhemikhali kwiYunivesithi yeTekhnoloji yaseChalmers.
"Ekubeni zonke iibhetri zine-aluminiyam, kufuneka sikwazi ukuyisusa ngaphandle kokulahlekelwa zezinye iintsimbi."
Kwilabhoratri yabo yokuphinda kusetyenziswe iibhetri, uRouquette kunye nenkokeli yophando uPetranikova babeke iibhetri zeemoto ezisetyenzisiweyo kunye nezinto ezicoliweyo kwindawo yokufutha.
Umgubo omnyama ocoliweyo unyibilikiswa kulwelo olucacileyo lwe-organic olubizwa ngokuba yi-oxalic acid, isithako esiluhlaza esifumaneka kwizityalo ezifana ne-rhubarb kunye ne-spinach.
Beka umgubo kunye nolwelo kumatshini ofana ne-blender yasekhitshini. Apha, i-aluminium kunye ne-lithium ebhetri ziyanyibilika kwi-oxalic acid, zishiye ezinye iintsimbi zikwimo eqinileyo.
Inyathelo lokugqibela kule nkqubo kukwahlula ezi zinyithi ukuze kukhutshwe i-lithium, enokusetyenziselwa ukwenza iibhetri ezintsha.
“Ngenxa yokuba ezi zinyithi zineempawu ezahlukeneyo kakhulu, asicingi ukuba kuya kuba nzima ukuzihlulahlula. Indlela yethu yindlela entsha ethembisayo yokuphinda usebenzise iibhetri ekufanele ukuba siyihlolisise ngakumbi,” utshilo uRouquette.
Iqela lophando likaPetranikova lichithe iminyaka lisenza uphando oluphambili malunga nokurisayikilisha izinyithi kwiibhetri ze-lithium-ion.
Ubandakanyeka kwiiprojekthi ezahlukeneyo zentsebenziswano neenkampani ezibandakanyeka ekusetyenzisweni kwakhona kweebhetri zezithuthi zombane. Eli qela liqabane kwiiprojekthi ezinkulu zophando nophuhliso kwaye iimpawu zalo ziquka iVolvo kunye neNorthvolt.
