ExxonMobil Chemical’s Japanese affiliate and Japan’s Toray Industries are forming a 50-50 joint venture to develop and make separator films for lithium-ion batteries. ExxonMobil will contribute its polyethylene separator film business, and Toray brings film processing technology and polymer science. Toray also will invest an undisclosed amount. The partners say they will sell into the personal-electronics market and the emerging electric vehicle field.
