Recharged for your Car: Silicon-carbon electrodes

A study that examines a new type of silicon-carbon nanocomposite electrode reveals details of how they function and how repeated use could wear them down. Silicon-carbon nanocomposite electrodes could lead to longer-lasting, cheaper rechargeable batteries for electric vehicles. The study includes videos of the electrodes being charged at a microscopic resolution which help researchers understand the strengths and weaknesses of the material. Lead researcher Chongmin Wang stated that the electrodes expand as they get charged, which shortens the battery lifespan. The Department of Energy’s Pacific Northwest National Laboratory recognizes the importance of learning how to improve their lifespan, because silicon carbon nanofiber electrodes have great potential for rechargeable batteries.
