Hauv kev siv thawj zaug, cov qauv ntsuas ntsuas yuav tsum tau txiav txim siab ua ke nrog cov peev txheej tsim khoom tiag tiag lossis cov qauv xav tau. Tom qab txheeb xyuas cov ntsuas ntsuas, kev soj ntsuam zoo tuaj yeem ua tau rau txhua pawg ntawm cov khoom siv raw.

ncaj qha cuam tshuam qhov sib xws ntawm cov roj teeb ua haujlwm. Indicators such as electrode surface density, compaction density, and resistance are strongly correlated with coating uniformity. Rolling txheej txheem - kuaj lub thickness ntawm electrode thiab compaction ceev tom qab dov. Cov txheej txheem dov cuam tshuam rau lub zog txhua yam thiab kev ua haujlwm ntawm electrochemical ntawm electrode. Cov txheej txheem sib dhos - kuaj qhov tseeb ntawm kev sib dhos thiab kev sib khi ntawm lub roj teeb. Kev ruaj ntseg ntawm cov txheej txheem sib dhos ncaj qha cuam tshuam rau kev nyab xeeb thiab kev pabcuam lub neej ntawm lub roj teeb. Txoj kev txhaj tshuaj electrolyte - kuaj tus nqi ntawm cov tshuaj electrolyte thiab nws qhov kev faib tawm. Qhov tseeb ntawm cov txheej txheem txhaj tshuaj electrolyte cuam tshuam rau sab hauv thiab kev ua haujlwm ntawm lub roj teeb.

Nrog rau txoj kev loj hlob sai ntawm kev lag luam thiab qhov tshwm sim ntawm cov kev xav tau tshiab, cov txheej txheem tshiab thiab kev sim tshuab yog xav tau rau lithium roj teeb txheej txheem kev ntsuas kev ruaj ntseg. Tus cwj pwm ntawm electrode wetting yeej ib txwm ua kom pom tseeb ntawm kev lag luam. (A) qhia txog cov txheej txheem capillary wetting, qhov siab - qhov pom kev pom qhov tseeb ua ke nrog kev tswj hwm thiab ntsuas qhov ntsuas tau zoo ntsuas cov nyhuv capillary wetting ntawm qib electrode; (B) thiab (C) qhia txog kev ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov siab thiab ntsuas qhov ntsuas qhov ntsuas qhov siab, uas tuaj yeem ntsuas qhov kev ua haujlwm ntub dej ntawm cov electrode los ntawm qhov sib txawv. Electrode electrolyte wetting yog ze ze rau lub roj teeb hluav taws xob ua haujlwm; Kev ntub dej txaus tuaj yeem txo cov kev tiv thaiv sab hauv, ua kom muaj peev xwm, txhim kho tus nqi kev ua tau zoo, thiab txuas ntxiv lub neej voj voog. Optimizing cov txheej txheem ntub dej yog qhov tseem ceeb rau kev txhim kho roj teeb kev ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov xws lilub zog cia solar panels

Kev ntsuam xyuas cov khoom tiav yog cov kauj ruam kawg hauv kev ua kom cov roj teeb zoo ua ntej lawv tawm hauv lub hoobkas. Nws feem ntau suav nrog kev ntsuas hluav taws xob: kuaj lub roj teeb lub peev xwm, kev ua haujlwm sab hauv, lub neej voj voog, kev ua haujlwm ntawm tus nqi, thiab lwm yam. Kev ntsuas hluav taws xob yog cov txheej txheem tseem ceeb rau kev ntsuas roj teeb. Kev soj ntsuam kev nyab xeeb: kev ua haujlwm dhau, overdischarge, luv Circuit Court, extrusion, puncture, thiab siab - ntsuas kub. Kev ntsuam xyuas kev nyab xeeb yog ib feem tseem ceeb ntawm kev ntsuas kev nyab xeeb ntawm roj teeb. Environmental adaptability testing: kuaj lub roj teeb kev ua tau zoo nyob rau hauv siab thiab qis kub, av noo, vibration, thiab lwm yam.

Kev ntsuas kev hloov pauv ib puag ncig yog qhov tseem ceeb rau kev ntsuas kev ntseeg tau ntawm lub roj teeb hauv kev siv tiag tiag, suav nrog lwm txoj hauv kev zoo litsev flywheel zog cialos yog advancedhuab zog roj teebtshuab. Qhov tseem ceeb ntawm kev ntsuas hluav taws xob ua tau zoo yog tus kheej - pom tseeb. Txhua tus paub tias cov pob roj teeb feem ntau yog tsim los ntawm ntau pua lossis ntau txhiab tus neeg lub hlwb.
