Cov roj teeb pob lithium feem ntau yog ua los ntawm lithium hlau lossis lithium alloy ua cov khoom siv anode thiab carbon raws li cov cathode, thiab cov tshuaj electrolyte uas ua rau cov electrons ntws ntawm cov anode thiab cathode.
Cov khoom siv cathode siv hauv lithium npib hlwb tuaj yeem sib txawv.Cov khoom siv cathode feem ntau siv rau cov roj teeb lithium yog lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4) thiab lithium hlau phosphate (LiFePO4).Txhua yam ntawm cov ntaub ntawv cathode no muaj nws tus kheej cov khoom tshwj xeeb uas ua rau nws haum rau ntau hom kev siv.
Li-SOCL2 yog lub roj teeb nrov tshaj plaws, thiab pkcell tau txuas ntxiv txhim kho kev ua tau zoo ntawm Li-SOCL2 xyoo ntawm kev tshawb fawb thiab kev loj hlob, thiab tau lees paub los ntawm ntau cov neeg siv khoom.
Lithium cobalt oxide (LiCoO2) yog cov khoom siv cathode tshaj plaws hauv cov roj teeb lithium.Nws muaj lub zog siab ceev thiab lub neej ntev ntev, lub ntsiab lus nws tuaj yeem them thiab siv ntau zaus ua ntej swb.Txawm li cas los xij, nws kuj tseem kim dua li lwm cov ntaub ntawv cathode.
Lithium manganese oxide (LiMn2O4) yog lwm cov khoom siv cathode siv hauv lithium npib hlwb.Nws muaj zog tsawg dua li LiCoO2, tab sis nws ruaj khov thiab tsis tshua muaj cua sov.Qhov no ua rau nws zoo tagnrho rau cov khoom siv hluav taws xob tshaib plab xws li cov koob yees duab digital thiab cov khoom siv CD portable.Li-MnO2 Roj teeb yog ib lub roj teeb nrov tshaj plaws hauv PKCELL
Lithium hlau phosphate (LiFePO4) yog cov khoom siv cathode tshiab uas tau txais koob meej hauv cov roj teeb lithium npib ntawm tes.Nws muaj lub zog qis dua li LiCoO2 thiab LiMn2O4, tab sis muaj kev ruaj khov thiab muaj kev nyab xeeb dua, muaj kev pheej hmoo tsawg heev ntawm kev kub dhau lossis hluav taws kub.Tsis tas li ntawd, nws muaj kev ruaj ntseg thermal thiab tshuaj lom neeg, ua rau nws tsim nyog rau kev kub siab thiab kev siv hluav taws xob siab.
Cov electrolyte siv hauv lithium khawm roj teeb tuaj yeem ua kua lossis khoom.Cov kua electrolytes siv feem ntau yog lithium ntsev nyob rau hauv cov kuab tshuaj organic, thaum cov khoom electrolytes yog lithium ntsev embedded nyob rau hauv cov khoom polymers los yog inorganic cov ntaub ntawv.Cov khoom electrolytes feem ntau muaj kev nyab xeeb dua li cov kua electrolytes.
