New silicon anodes could help EV batteries go farther charge faster

Two U.S. start-ups, Group14 Technologies and Sila Nanotechnologies, are set to bring new-generation electric vehicle batteries to market by mid-decade powered by new silicon-based electrodes. The material, which is being developed as a supplement or replacement for graphite in battery anodes, will be produced in commercial-grade facilities next year in central Washington state. A new generation of electric vehicle (EV) batteries that hold more energy, achieve longer driving range and charge more quickly should begin reaching customers by mid-decade, powered by new silicon-based electrodes that are slated to go into production next year in central Washington state.
