n cov txheej txheem tsim khoom ntawm lithium-ion roj teeb, feem ntau muaj ntau txoj hauv kev los faib cov txheej txheem. Cov txheej txheem tuaj yeem muab faib ua peb yam tseem ceeb: kev tsim hluav taws xob, txheej txheem sib dhos thiab kev sim ntawm tes (raws li qhia hauv daim duab hauv qab no), thiab tseem muaj cov tuam txhab uas faib nws ua ntej-winding thiab post-winding cov txheej txheem, thiab qhov demarcation point yog. txoj kev winding. Vim nws txoj kev sib koom ua ke muaj zog, tuaj yeem ua rau lub roj teeb zoo li pib molding, yog li cov txheej txheem winding hauv lithium-ion roj teeb tsim ua lub luag haujlwm tseem ceeb, yog qhov tseem ceeb, cov txheej txheem winding tsim los ntawm cov tub ntxhais dov feem ntau hu ua liab qab. roj teeb cell (Jelly-Roll, hu ua JR).
