Cov txheej txheem winding ntawm lithium-ion roj teeb yog dov daim ntawv zoo electrode, daim ntawv tsis zoo electrode thiab cais ua ke los ntawm winding koob mechanism ntawm lub tshuab winding. Cov nplooj ntawv zoo thiab tsis zoo electrode uas nyob ib sab yog cais los ntawm cov khoom sib cais los tiv thaiv luv luv Circuit Court. Tom qab winding, lub jelly yob yog tsau nrog ib tug txiav daim kab xev los tiv thaiv nws los ntawm kis, thiab ces nws ntws mus rau cov txheej txheem tom ntej. Qhov tseem ceeb tshaj plaws nyob rau hauv cov txheej txheem no yog kom ntseeg tau tias tsis muaj kev sib cuag lub cev luv luv ntawm qhov zoo thiab qhov tsis zoo electrodes, thiab cov ntawv tsis zoo electrode tuaj yeem npog cov ntawv electrode zoo hauv ob qho tib si kab rov tav thiab ntsug.
Ib tug loj npaum li cas ntawm kev sim cov ntaub ntawv qhia tau hais tias qhov zoo ntawm jelly yob muaj ib tug tseem ceeb cuam tshuam rau lub electrochemical kev ua tau zoo thiab kev nyab xeeb kev ua tau zoo ntawm lub kawg tiav roj teeb. Raws li qhov no, peb tau txheeb xyuas qee qhov tseem ceeb thiab kev ceev faj hauv cov txheej txheem winding ntawm lithium-ion roj teeb thiab tsim "Lithium-ion Battery Winding Process Guide". Peb cia siab tias yuav tsum tsis txhob ua haujlwm tsis raug hauv cov txheej txheem winding kom ntau li ntau tau, txhawm rau tsim cov roj teeb lithium-ion uas ua tau raws li qhov yuav tsum tau ua.
