PVDF (DS202D) Resin Rau Lithium roj teeb Electrodes Binder Cov ntaub ntawv
PVDF hmoov DS202D yog homopolymer ntawm vinylidene fluoride, uas yuav siv tau rau electrodes binder cov ntaub ntawv nyob rau hauv lithium roj teeb.DS202D yog ib yam ntawm polyvinylidene fluoride nrog siab molecular hnyav.Nws yog soluble nyob rau hauv polar organic hnyav. yooj yim zaj duab xis-forming.Cov khoom siv electrode uas yog tsim los ntawm PVDF DS202D muaj tshuaj zoo stability, kub stability thiab zoo processability.As ib tug ntawm cov binders, PVDF yog dav siv nyob rau hauv lub teb ntawm lithium-ion roj teeb.Nws txuas cov khoom siv hluav taws xob hluav taws xob, tus neeg sawv cev thiab cov khoom siv tam sim no nrog rau ib leeg, kev ua haujlwm thiab ntau npaum li cas ntawm PVDF binder muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm electrochemical ntawm lithium roj teeb.Feem ntau, siab adhesion tuaj yeem txhim kho lub neej voj voog ntawm lithium roj teeb, thiab lub ntsiab tseem ceeb cuam tshuam rau qhov adhesion yog qhov hnyav molecular thiab crystallinity.
