Separator of lithium-ion battery

Product Portfolio

Separator is a key material for lithium-ion batteries. Its primary function is to separate the positive and negative electrodes, preventing short circuits while allowing electrolyte ions to pass through. The company has developed a wide range of product solutions, including three major series with dozens of variants to meet customer demands.
