Sodium Na ion Battery Separator Battery Raw Materials for Coin cell Battery ResearchProduct
Product Description
PE PP PP/PE/PP Multi layers Battery Separator with Customized Width
PE & PP separators are used for lithium-ion battery manufacturers and researchers. The materials consist of Polymer film , that are either Polypropylene (PP) or Polyethylene (PE) based. contain micro and nano pores to provide excellent ion transportation capabilities within the li-ion battery.
Also Ceramic-coated variety for enhanced thermal deformation resistance and mechanical strength.
