Battery Paper (0.3 mm, 0.4 mm & 0.5 mm)

The separator is one of the most critical materials in the structure of the lithium-ion battery.

Based on the differences in physical and chemical properties, generally, we categorize lithium-ion battery separators as woven separators, non-woven separators (non-woven fabrics), microporous membranes, composite separators, separator paper, etc.

Although there are various types of battery separators on the market, the commercialized Li-ion battery separators are mainly polyolefin membranes.

According to the separator structure and composition of battery separators, the market’s most popular li-ion battery separators are porous polymer membranes, non-woven separators and inorganic composite films.
