Cov roj teeb cia hauv tsev ua haujlwm raws li cov nqi hluav taws xob hluav taws xob- cov tshuaj tiv thaiv tawm. Noj lithium-ion roj teeb ua piv txwv, thaum them nyiaj, lub zog hluav taws xob sab nraud xa hluav taws xob rau lub roj teeb. Lithium ions raug tso tawm los ntawm cov khoom siv electrode zoo, dhau los ntawm cov tshuaj electrolyte, thiab muab tso rau hauv cov khoom tsis zoo electrode. Nyob rau tib lub sijhawm, electrons ntws los ntawm qhov zoo mus rau qhov tsis zoo electrode los ntawm ib qho hluav taws xob sab nraud, ua kom tiav cov txheej txheem them nyiaj thiab khaws cov hluav taws xob ua hluav taws xob ua hluav taws xob.
Thaum tso tawm, qhov xwm txheej yog thim rov qab. Lub zog tshuaj yog hloov mus rau hauv hluav taws xob hluav taws xob. Lithium ions raug tso tawm los ntawm qhov tsis zoo electrode thiab rov qab mus rau qhov zoo electrode, thaum electrons ntws los ntawm qhov tsis zoo electrode mus rau qhov zoo electrode los ntawm ib qho hluav taws xob sab nraud, muab lub zog rau cov khoom siv hluav taws xob txuas. Cov txheej txheem no txuas ntxiv mus, ua tiav qhov kev cia thiab tso tawm hluav taws xob kom ua tau raws li tsev neeg cov kev xav tau hluav taws xob nyob rau lub sijhawm sib txawv.
