Freudenberg non-woven membrane technology introduced into China

For a long time, electric vehicles have faced the problem that lithium batteries are limited by their inherent characteristics, making it difficult to eliminate fire hazards. To meet this challenge, the German Freudenberg Group has developed a new technology for making battery separators from non-woven materials. This innovative technology and process allows lithium ions to flow more freely and ensures that the battery is highly fire-resistant. Recently, Freudenberg announced to introduce this safe storage battery technology into China.

According to reports, Freudenberg's new technology applies a specially developed inorganic coating on the surface of the separator. When the internal temperature of the battery rises, the separator does not shrink or melt, which greatly improves the safety of the battery.
