Sumitomo Chemical will more than double its production capacity for lithium-ion secondary battery separators, marketed under the PERVIO brand name. PERVIO is chiefly used in automotive battery cells through its use in Panasonic’s high-capacity and high-energy density cylindrical lithium-ion secondary batteries. Through Panasonic, the cells with PERVIO separators are used in Tesla Motors’ Model S.
