Iibhetri zeqhosha le-Lithium zenziwe ngokukodwa nge-lithium metal okanye i-lithium alloy njenge-anode kunye ne-carbon material njenge-cathode, kunye nesisombululo se-electrolyte esenza ukuba ii-electron zihambe phakathi kwe-anode kunye ne-cathode.
Izinto zeCathode ezisetyenziswe kwiiseli ze-lithium coin zinokuhluka.Izinto ezisetyenziswa ngokuqhelekileyo zecathode kwiibhetri ze-lithium iqhosha le-lithium cobalt oxide (LiCoO2), i-lithium manganese oxide (LiMn2O4) kunye ne-lithium iron phosphate (LiFePO4).Nganye kwezi zixhobo ze-cathode zinesethi yayo ekhethekileyo yeepropati ezenza ukuba zilungele iintlobo ezahlukeneyo zezicelo.
I-Li-SOCL2 yeyona bhetri idumileyo, kwaye i-pkcell iye yaphucula ngokuqhubekayo ukusebenza kwe-Li-SOCL2 kwiminyaka yophando nophuhliso, kwaye yamkelwa ngabathengi abaninzi.
I-Lithium cobalt oxide (i-LiCoO2) yeyona nto isetyenziswa kakhulu kwi-cathode impahla kwiibhetri zeqhosha le-lithium.Inoxinano olukhulu lwamandla kunye nobomi bomjikelo omde ngokwentelekiso, oku kuthetha ukuba inokubizwa kwaye isetyenziswe amaxesha amaninzi phambi kokuba ilahlekelwe ngumthamo.Nangona kunjalo, iyabiza kakhulu kunezinye izinto ze-cathode.
I-Lithium manganese oxide (i-LiMn2O4) yenye into eqhelekileyo ye-cathode esetyenziswa kwiiseli ze-lithium coin.Inoxinano lwamandla asezantsi kune-LiCoO2, kodwa izinzile kwaye ayifuni kakhulu ukutshisa.Oku kuyenza ilungele izixhobo ezilambele amandla njengeekhamera zedijithali kunye neesidlali zeCD eziphathwayo.I-Li-MnO2 Ibhetri yenye yezona bhetri zidumileyo kwi-PKCELL
I-Lithium iron phosphate (LiFePO4) yinto entsha ye-cathode efumana ukuthandwa kwiibhetri zeeseli ze-lithium.Inoxinano lwamandla aphantsi kune-LiCoO2 kunye ne-LiMn2O4, kodwa izinzile kwaye ikhuselekile, kunye nomngcipheko ophantsi kakhulu wokutshisa okanye umlilo.Ukongezelela, inozinzo oluphezulu lwe-thermal kunye neekhemikhali, okwenza ukuba lulungele ubushushu obuphezulu kunye nezicelo zamandla aphezulu.
I-electrolyte esetyenziswa kwiibhetri ze-lithium iqhosha linokuba lulwelo okanye lube luqilima.I-electrolyte yolwelo esetyenziswayo idla ngokuba ziityuwa ze-lithium kwizinyibilikisi zendalo, ngelixa i-electrolyte eqinileyo ziityuwa ze-lithium ezifakwe kwiipolima eziqinileyo okanye izinto ezingaphiliyo.Ii-electrolyte eziqinileyo zikhuselekile ngokubanzi kune-electrolyte ezingamanzi.
