Cov khoom siv roj teeb lithium

Lub roj teeb Li muaj tshwj xeeb ntawm cov hlau lithium anode thiab sulfur cathode. Lub ntsiab kom zoo dua ntawm lub roj teeb no yog hloov cov sib xyaw oxide ntawm cathode los ntawm leej faj, sib dua, ntau dua, thiab yog li pheej yig. Cov khoom siv hauv lithium roj teeb cathode muaj xws li lithium-hlau oxides [xws li Li (NixMnyCoz)O₂, LiMn₂O_4,and LiCoO₂], olivines (xws li LiFePO₄), vanadium oxides thiab rechargeable lithium oxides. Cov ntaub ntawv uas siv hauv anodes muaj xws li lithium-alloying cov ntaub ntawv, graphite, silicon, los yog intermetallic. Graphite carbon yog ib daim ntawv ntawm cov pa roj carbon nrog cov qauv laminated. Qhov chaw nruab nrab ntawm cathode thiab anode yog ntim nrog ib qho electrolyte, uas yog ib yam khoom tso cai rau cov lithium ions uas nqa cov nqi ntawm lub roj teeb kom dhau los ntawm cathode mus rau anode. Cov electrolytes ntawm lithium roj teeb yog polymer, kua, los yog solid-state electrolytes. Yog tias cov electrolyte yog cov kua, ces siv lub tshuab ua npuas dej sib cais ntawm ob lub electrodes kom tsis txhob muaj luv luv.
