PP Battery Separator

Catalog Number: ACM-BS03

Thickness: 25 μm

Primary Application: Lithium-ionbattery systems

Packaging Type: As per requirement

Product Description

PP battery separator is a type of barrier used in rechargeable lithium-ion batteries to separate the positive and negative electrodes while allowing ions to flow between the positive and negative electrodes. PP stands for polypropylene, which is a thermoplastic polymer material that is known for its high thermal stability, chemical resistance, and mechanical strength. As a thin, microporous membrane, PP battery separator is permeable to ions but not electrons. This helps prevent short circuits and improves the overall performance and safety of lithium-ion batteries. As a leading supplier of battery materials, our company is committed to providing you with PP battery separator with excellent performance. If our product piques your interest, please do not hesitate to contact us.
