Lithium-ion Batteries Enabled by Silicon Anodes

Deploying lithium-ion (Li-ion) batteries depends on cost-effective electrode materials with high energy and power density to facilitate lower weight and volume. Si-based anode materials theoretically offer superior lithium storage capacity. Replacing a graphite anode with high-capacity materials such as silicon will further improve the energy density. Durable, low-cost, and high-energy-density materials are vital to developing plug-in electric vehicles as affordable and convenient as gasoline-powered ones, while reducing carbon emissions.
