A Pacific Northwest National Laboratory study has examined a new type of silicon-carbon nanocomposite electrode. The research shows how they function and how they wear down. The research suggests why this material performs better than silicon alone. With a capacity five times higher than conventional lithium battery electrodes, silicon-carbon nanocomposite electrodes could be developed into longer-lasting, cheaper rechargeable batteries for use in electric vehicles.
