Cov hlau oxides nrog cov txheej txheem ruaj khov inorganic skeleton feem ntau qhia txog lub neej ntev heev, tab sis vim lawv cov molecular loj, qhov tshwj xeeb muaj peev xwm feem ntau tsis tshua muaj, thiab nws nyuaj rau ua tau raws li cov kev xav tau ntawm kev lag luam.
Qhov loj tshaj plaws ntawm cov ntaub ntawv organic anode yog tus nqi qis thiab cov qauv sib txawv, tab sis tseem muaj ntau yam teeb meem, xws li: qis thawj lub voj coulomb efficiency, polarization teeb meem thaum caij tsheb kauj vab, tsis tshua muaj hluav taws xob conductance, dissolution ntawm cov organic molecules hauv electrolytes thiab lwm yam. Feem ntau, txoj kev loj hlob ntawm cov organic sodium ion roj teeb muaj peev xwm zoo, tab sis tam sim no kev tshawb fawb ntawm cov ntaub ntawv no tseem nyob rau hauv nws cov me nyuam mos.
Qhov teeb meem loj tshaj plaws ntawm cov khoom siv anode raws li kev hloov pauv thiab cov tshuaj tiv thaiv alloying yog qhov hloov pauv loj hauv cov txheej txheem ntawm kev tshem tawm sodium ua rau cov hmoov ntawm cov khoom siv, ua rau muaj peev xwm sai sai.
Carbon-based anode cov ntaub ntawv tsuas yog xa mus rau amorphous carbon (xws li cov roj carbon tawv thiab cov pa roj carbon monoxide). Tam sim no, lub luag haujlwm tseem ceeb tsom mus rau inhibiting lub peev xwm lwj hauv cov txheej txheem voj voog thiab txhim kho thawj lub voj coulomb efficiency. Lub peev xwm tshwj xeeb ntawm cov pa roj carbon monoxide thiab txo qis graphene oxides tuaj yeem siab heev, tab sis qhov sib txuam ua haujlwm voltage kuj siab. Yog li ntawd, kev tshawb fawb tsom ntawm cov ntaub ntawv no tsis yog tsuas yog los txhim kho thawj lub voj coulomb efficiency, tab sis kuj ntxiv txo qhov kev khiav hauj lwm voltage. Raws li tuaj yeem pom los ntawm daim duab 3, cov roj carbon tawv (HC) feem ntau muaj qhov ua haujlwm qis thiab muaj peev xwm siab, thiab yog li ntawd, qhov tsis zoo electrode siv hauv cov khoom lag luam sodium-ion roj teeb tam sim no yuav luag txhua cov roj carbon.
