Comprehensive understanding about battery separator-concept,

According to the separator pore formation mechanism, the separator production process can be currently divided into two types: dry production and wet production. The primary difference between the two types of battery separator production is that dry production requires the manufacturer to first exturd, then anneal, and finally stretch the material.

Dry vs Wet Separator Technology

PE Wet Separator: the separator is produced using solvents. Wet separator is thinner and hence enables higher energy density at cell level. Wet separator is easier to pass nail penetration test. Dry separator is more environment friendly. China produces around 80% of the world''s separators.
