Tonen's Performance Separators

Tonen Chemical Corp.'s microporous film Li-ion battery (LIB) separators (shown on page 1) are expected to significantly improve LIB power and safety performance in hybrid electric vehicle applications. The separators could make HEV batteries lighter in weight and smaller, thereby reducing system costs while improving design flexibility and durability.

The advanced performance separator films have higher melt integrity and a significant reduction in heat shrinkage, while maintaining good permeability and tensile strength compared to standard separators. In addition, the separators were developed for safety, quality and value featuring excellent melt down and shut-down properties and uniquely balanced LIB power capacity and density.
