Raising capacity of lithium-ion batteries for electric vehicles

The energy storage market is continuously aiming to raise capacity for applications such as electric vehicles. In this areas, Ashland has introduced Soteras MSi binder which is based on a breakthrough technology specifically for use with silicon to increase the capacity of lithium-ion batteries by as much as 30%.

This step-change in battery capacity could prove significant for cell developers supplying the electric vehicle market. Soteras MSi binder is a water-based binder that can easily be processed using standard industry practices. It controls swelling, resulting in superior cycle performance at capacities greater than 400 mAh/g when used with silicon oxide (SiO), silicon composite (SiC), silicon oxide composite (SiOC), or silicon graphene (Si-Gr) technologies.

Acoording to Dr. Robert Gibbison, marketing director, Industrial Specialties at  Ashland, the range of Soteras binders including Soteras MSi binder can help cell developers higher capacity substantially altering their standard manufacturing processes.
