"Lithium-ion roj teeb kev lag luam tus qauv (2021)" kuj xav kom cov tuam txhab siv cov cuab yeej siv siab heev, txuag hluav taws xob, ib puag ncig tus phooj ywg, nyab xeeb thiab ruaj khov, thiab cov txheej txheem tsim khoom thiab cov khoom siv ntse ntse, thiab ua tau raws li cov hauv qab no: 1. Lithium-ion Cov tuam txhab roj teeb yuav tsum muaj lub peev xwm los saib xyuas qhov sib xws ntawm cov electrode tom qab txheej, thiab kev tswj xyuas qhov tseeb ntawm electrode txheej thickness thiab ntev tsis tsawg dua 2μm thiab 1mm feem; nws yuav tsum muaj electrode ziab tshuab, thiab cov dej cov ntsiab lus tswj qhov tseeb yuav tsum tsis txhob tsawg dua 10ppm. 2. Cov tuam txhab roj teeb lithium-ion yuav tsum muaj peev xwm tswj hwm ib puag ncig xws li kub, av noo thiab huv si thaum lub sijhawm txhaj tshuaj; lawv yuav tsum muaj peev xwm txheeb xyuas qhov ntsuas hluav taws xob luv luv hauv high-voltage test (HI-POT) on-line tom qab sib dhos roj teeb. 3. Lithium-ion roj teeb pob cov lag luam yuav tsum muaj peev xwm tswj tau qhov qhib hluav taws xob hluav taws xob thiab kev tiv thaiv sab hauv ntawm tib lub hlwb, thiab kev tswj xyuas qhov tseeb yuav tsum tsis pub tsawg dua 1mV thiab 1mΩ raws li; lawv yuav tsum muaj peev xwm txheeb xyuas lub roj teeb pob tiv thaiv pawg thawj coj ua haujlwm hauv online.
