Aluminium- yas zaj duab xis yog cov khoom tseem ceeb uas siv dav hauv lithium- ion roj teeb ntim, feem ntau yog tsim los ntawm peb txheej sib txuas ua ke nrog cov nplaum. Los ntawm sab nraud hauv, cov no yog txheej txheej txheej txheej, txheej txheej permeation barrier, thiab cua sov- txheej sealing.
Txheej Txheej Txheej Txheej Txheej: Feem ntau ua los ntawm nylon (PA), nws muaj qhov cuam tshuam tsis kam, puncture tsis kam, tsis kam tiv thaiv, thiab cov khoom cua sov. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv cov ntawv txhuas sab hauv los ntawm kev puas tsuaj rau lub cev thaum tiv thaiv huab cua nkag mus, ua kom lub ntim ntim airtightness thiab deformation tsis kam.
Permeation Barrier Layer: Cov ntsiab lus tseem ceeb yog aluminium ntawv ci, nthuav tawm cov pinhole zoo heev thiab ob -sided lamination. Aluminium foil reacts nrog huab cua ntawm chav tsev kub los tsim cov oxide zaj duab xis, zoo thaiv cov dej noo thiab oxygen, tiv thaiv cov roj teeb sab hauv. Tsis tas li ntawd, txheej txheej aluminium ntawv tseem yog cov qauv txhawb nqa rau qhov sib sib zog nqus-drilling deformation ntawm aluminium- zaj duab xis yas.
Thaum tshav kub kub-Sealing Layer: Feem ntau yog ua los ntawm polypropylene zaj duab xis (CPP), nws muaj cua sov zoo- sealing zog, rwb thaiv tsev, thiab tiv thaiv electrolyte corrosion. Thaum lub sij hawm encapsulation txheej txheem, PP txheej yog rhuab thiab melted rau adhere, kom lub roj teeb lub airtightness thaum tiv thaiv electrolyte to thiab corrosion ntawm txhuas ntawv ci.
Adhesives: Adhesives siv nyob rau hauv composite peb- cov ntaub ntawv txheej yuav tsum muaj kev tiv thaiv rau electrolytes, kub kub, laus, thiab muaj zog adhesion. Cov hom nplaum nplaum muaj xws li hnyav-dawb polyurethane adhesives thiab benzene-dawb polyurethane adhesives (cawv-soluble los yog dej-raws li).
