Cov ntaub ntawv siv los tsim cov roj teeb cia lub zog feem ntau suav nrog cov khoom siv cathode, cov khoom siv anode, electrolytes, cov khoom sib cais, thiab cov khoom siv sab nraud. Kev xaiv ntawm cov ntaub ntawv ncaj qha cuam tshuam rau lub roj teeb lub zog ceev, lub neej voj voog, kev nyab xeeb kev ua tau zoo, thiab kev them nqi - tso tawm efficiency. Tam sim no, dav siv cov roj teeb cia lub zog feem ntau siv cov lithium-ion qauv; Cov ntaub ntawv cathode feem ntau suav nrog lithium hlau phosphate (LFP) thiab cov ntaub ntawv ternary, thaum cov ntaub ntawv anode feem ntau muaj cov pa roj carbon-raws li cov ntaub ntawv xws li graphite. Cov ntaub ntawv no muaj kev ruaj ntseg electrochemical zoo heev, ua tau raws li qhov xav tau ntawm kev ua haujlwm ntev - lub sijhawm ua haujlwm hauv lub zog cia.
Electrolytes thiab cov khoom sib cais yog cov khoom tseem ceeb hauv cov roj teeb cia. Cov electrolyte ua kom yooj yim rau kev thauj cov lithium ions, ua kom muaj zog ion thaum lub sij hawm them nyiaj thiab tawm cov txheej txheem, thaum lub separator khaws cov cathode thiab anode cov ntaub ntawv sib nrug - tiv thaiv luv luv Circuit Court tshwm sim los ntawm kev sib cuag ncaj qha - tseem tso cai rau ions hla. Txhawm rau txhim kho kev nyab xeeb thiab kev pab cuam lub neej, niaj hnub lub zog cia roj teeb siv cov khoom sib cais nrog cov khoom siv hluav taws xob zoo tshaj plaws thiab cov khoom siv dag zog, thiab siv cov txheej txheem electrolyte zoo kom ntseeg tau tias kev ua haujlwm ruaj khov nyob rau ntau qhov chaw ua haujlwm.
Cov qauv sab nraud ntawm lub zog cia roj teeb feem ntau suav nrog cov hlau casing, cov ntaub ntawv insulating, thiab cov khoom cua sov-dissipating. Roj teeb casings feem ntau yog ua los ntawm txhuas alloy los yog hlau los xyuas kom meej cov qauv kev ruaj ntseg thiab ruaj khov; insulating cov ntaub ntawv txo cov kev pheej hmoo ntawm hluav taws xob to thiab luv circuits; thiab cua sov- cov ntaub ntawv dissipating tswj kev ua haujlwm kub kom ntseeg tau tias cov cuab yeej muaj kev nyab xeeb thiab ruaj khov. Raws li lub zog cia thev naus laus zis nce qib, cov khoom siv roj teeb tau hloov mus rau kev ua haujlwm siab, kev phooj ywg ib puag ncig, thiab kev ruaj khov; kev txais yuav cov ntaub ntawv tshiab thiab txhim kho cov txheej txheem tsim khoom txuas ntxiv txhim kho tag nrho cov kev ua tau zoo ntawm lub zog cia roj teeb.
