25 Micron High Quality China Polyethylene PE PP Lithium Ion Battery Separator
Requirements for Lithium Battery Separator:
- Lithium ion separator has electronic insulation to ensure the mechanical separation of positive and negative poles.
- Lithium ion separator has a certain pore size and porosity to ensure low resistance and high ionic conductivity, and has good permeability to lithium ions.
- Since the solvent of the electrolyte is a strong polar organic compound, the diaphragm must be resistant to corrosion by the electrolyte and have sufficient chemical and electrochemical stability.
- Lithium ion separator has good wettability to the electrolyte and has sufficient liquid absorption and moisturizing ability.
- Lithium ion separator has sufficient mechanical properties, including puncture strength, tensile strength, etc., but the thickness is as small as possible.
- Lithium ion separator features good spatial stability and smoothness.
- Lithium ion separator has good thermal stability and automatic shutdown protection performance. Power batteries have higher requirements for diaphragms, and composite membranes are usually used.
Feature of Lithium Battery Separator:
- The main performance requirements of lithium ion battery separators include: Thickness uniformity, Mechanical properties (including tensile strength and puncture resistance), Air permeability, Physical and chemical properties (including wettability, chemical stability, thermal stability, safety), etc.
