Ntau qhov ua rau tawg hauv lithium-ion roj teeb muaj xws li:
1. Overcharge lossis overdischarge: Thaum lub charger voltage ntawm lithium-ion roj teeb siab dhau los yog qhov hluav taws xob tawm tsawg dhau, nws tuaj yeem ua rau cov lithium ions hauv cov electrolyte precipitate metallic lithium, tsim cov hlau lithium dendrites, ua rau luv luv Circuit Court. , thermal runaway, thiab lwm yam tshwm sim, ua rau tawg.
2. Kev puas tsuaj rau lub cev: Lub plhaub ntawm lub roj teeb lithium-ion tuaj yeem raug kev puas tsuaj ntawm lub cev, compression, puncture, thiab lwm yam, uas tuaj yeem ua rau luv luv ntawm qhov zoo thiab qhov tsis zoo electrodes, ua rau thermal runaway hauv lub roj teeb thiab thaum kawg ua rau kev tawg.
3. Qhov kub thiab txias: Nyob rau hauv ib puag ncig kub, cov electrolyte ntawm lithium-ion roj teeb evaporates, ua rau lub siab sab hauv ntawm lub roj teeb, uas yuav ua rau lub plhaub roj teeb tawg, tso roj, thiab ua rau tawg.
4. Kev tsim khoom tsis xws luag: Hauv kev tsim cov roj teeb lithium-ion, yog tias muaj kev xaiv cov khoom siv tsis raug, cov txheej txheem tsis xws luag, teeb meem khoom siv ntau lawm, thiab lwm yam, nws yuav ua rau tsis ruaj khov hauv cov qauv ntawm lub roj teeb, ua rau muaj kev pheej hmoo ntawm kev tawg.
5. Kev siv lub tshuab hluav taws xob tsis zoo: kev siv tsis raug lossis kev them nyiaj tsis zoo, xws li overcharging, tshaj tawm, tsis ruaj tsis khov, thiab lwm yam, yuav ua rau cov roj teeb lithium-ion overheat, luv Circuit Court, thiab thaum kawg ua rau tawg.
6. Sab nraud luv luv Circuit Court: Yog hais tias ib tug sab nraud luv luv Circuit Court tshwm sim ntawm qhov zoo thiab tsis zoo electrodes, xws li ib tug luv luv Circuit Court tshwm sim los ntawm kev sib cuag nrog ib tug hlau conductor, nws muaj peev xwm ua rau muaj kev kub ntxhov ntawm cov electrolyte nyob rau hauv lub roj teeb, ua rau tawg.
Hauv cov ntsiab lus, qhov tawg ntawm lithium-ion roj teeb tuaj yeem tshwm sim los ntawm kev sib xyaw ua ke xws li overcharge, overdischarging, kev puas tsuaj rau lub cev, kub siab, kev tsim khoom tsis xws luag, cov khoom siv tsis ua haujlwm, lossis cov khoom siv luv luv. Yog li ntawd, thaum siv cov roj teeb lithium-ion, nws yog ib qho tsim nyog yuav tsum ua raws li cov cai tswj kev siv kom ruaj ntseg.
