Intro
Introduction
We develop and produce multi-functional dry process type (uniaxial stretching) separator which is widely used in rechargeable lithium-ion batteries, secondary lithium batteries and a variety of energy storage batteries.
PE
Product #1
Polyethylene (PE) separator.
PP
Product #2
Polypropylene (PP) separator.
ML
Product #3
Multi-layer (PP/PE/PP) separator.
Our solution advantages.
High porosity
High porosity could increase the absorption of electrolytes in the separator, extend the cycle life, and reduce the resistance of diffusion of lithium-ion.
High permeability
High permeability could increase the ability of the cell to charge and discharge.
High safety
High tortuosity of the separator could avoid dendrite formation.
High uniformity
Homogeneous pore distribution creates high uniformity of the cell.
High strength
High strength could increase the yield rate of the cell.
