Soteras MSi Binder will debut at Battery Japan
Ashland has developed Soteras MSi, a new anode binder based on breakthrough technology specifically for use with silicon to increase the capacity of lithium ion batteries by as much as 30 percent. This step-change in battery capacity could prove significant for cell producers supplying the electric vehicle market.
Soteras MSi is a unique water-based binder for high-capacity silicon-based anodes in lithium ion batteries. It can easily be processed using standard industry practices. Soteras™ MSi controls swelling, resulting in superior cycle performance at capacities greater than 400mAh/g when used with silicon dioxide (SiOx), silicon composite (SiC), silicon oxidecomposite (SiOxC), or silicon graphene (Si-Gr) technologies.
"As the adoption of lithium ion batteries moves from consumer electronics to electric vehicles and mass storage, there is an increasing requirement for higher capacities and improved safety," said Dr. Robert Gibbison, marketing director, Industrial Specialties, Ashland. "The range of Soteras binders, including Soteras MSi, can help cell producers achieve these goals without substantially altering standard manufacturing processes."
