Mabatire a lithiamu amapangidwa makamaka ndi zitsulo za lithiamu kapena aloyi ya lithiamu monga anode ndi zinthu za carbon monga cathode, ndi njira ya electrolyte yomwe imathandizira ma elekitironi kuyenda pakati pa anode ndi cathode.
Zida za cathode zomwe zimagwiritsidwa ntchito m'maselo a lifiyamu zimatha kusiyana.Zomwe zimagwiritsidwa ntchito kwambiri ndi cathode za mabatire a lithiamu batani ndi lithiamu cobalt oxide (LiCoO2), lithiamu manganese oxide (LiMn2O4) ndi lithiamu iron phosphate (LiFePO4).Chilichonse mwazinthu za cathode zili ndi zida zake zomwe zimapangitsa kuti zikhale zoyenera kwa mitundu yosiyanasiyana ya ntchito.
Li-SOCL2 ndiye Battery yodziwika kwambiri, ndipo pkcell yakhala ikuwongolera magwiridwe antchito a Li-SOCL2 mzaka za kafukufuku ndi chitukuko, ndipo yadziwika ndi makasitomala ambiri.
Lithium cobalt oxide (LiCoO2) ndiye chinthu chogwiritsidwa ntchito kwambiri cha cathode mu mabatire a lithiamu batani.Imakhala ndi mphamvu zambiri komanso imakhala ndi moyo wautali wautali, kutanthauza kuti imatha kulipiritsa ndi kugwiritsidwa ntchito nthawi zambiri isanathe.Komabe, ndizokwera mtengo kwambiri kuposa zida zina za cathode.
Lithium manganese oxide (LiMn2O4) ndi chinthu china chodziwika bwino cha cathode chomwe chimagwiritsidwa ntchito m'maselo achitsulo a lithiamu.Imakhala ndi mphamvu zochepa kuposa LiCoO2, koma imakhala yokhazikika komanso yocheperako kutenthedwa.Izi zimapangitsa kukhala yabwino kwa zipangizo zanjala mphamvu monga makamera digito ndi kunyamula CD osewera.Li-MnO2 Battery ndi imodzi mwa mabatire otchuka kwambiri ku PKCELL
Lithium iron phosphate (LiFePO4) ndi chinthu chatsopano cha cathode chomwe chikudziwika bwino mu mabatire a lithiamu coin cell.Ili ndi mphamvu zochepa kuposa LiCoO2 ndi LiMn2O4, koma imakhala yokhazikika komanso yotetezeka, yokhala ndi chiopsezo chochepa cha kutentha kapena moto.Kuonjezera apo, imakhala ndi kutentha kwakukulu komanso kukhazikika kwa mankhwala, ndikupangitsa kuti ikhale yoyenera kutentha kwambiri komanso kugwiritsa ntchito mphamvu zambiri.
Ma electrolyte omwe amagwiritsidwa ntchito mu mabatire a lithiamu amatha kukhala amadzimadzi kapena olimba.The madzi electrolytes ntchito zambiri lifiyamu mchere mu zosungunulira organic, pamene olimba electrolytes ndi lifiyamu mchere ophatikizidwa mu ma polima olimba kapena zinthu inorganic.Ma electrolyte olimba nthawi zambiri amakhala otetezeka kuposa ma electrolyte amadzimadzi.
