Asahi Kasei is a pioneer in battery technology and a long-trusted supplier of lithium-ion battery separators, which are polymer-based microporous membranes that are among the most highly engineered and critical components of the lithium-ion batteries (LIB) used in electric vehicles (EV), electric grid energy storage solutions (ESS), and other applications.
Lithium-ion battery separators provide a barrier between the anode and cathode (the battery electrodes) to prevent short circuits, while performing the core function of facilitating ion exchange – which is required to produce energy.
The company’s wet-process separators have been commercially available since the lithium battery market’s inception in the early 1990s and are widely recognized for their contribution to battery safety and reliability.
Asahi Kasei's wet-process lithium-ion battery separators offer a number of unique advantages in battery systems and are especially well matched for the high-capacity batteries required to power plug-in hybrid (PHEV) and full battery (BEV) vehicles.
Key Properties:
- Uniform submicron pore structure
- High porosity
- Excellent thickness uniformity
- High puncture strength
- Wide range of thicknesses available
- Functional coatings available for enhanced separator performance
