Selecting a Battery Cell Separator

separator

Author Anita Liu Selecting the right separator for the right cell and application is critical. Material Defines Character Thickness & Porosity: The Balance of Thinness and Permeability Thickness: Typically 5~25 μm. Thinner separators facilitate ion transport and increase overall energy density (by saving space and weight), but raise the risk of being pierced by dendrites. … Read more
