Title: Silicon-Nanowire Based Lithium Ion Batteries for Vehicles With Double the Energy Density

Amprius researched and developed silicon nanowire anodes. Amprius then built and delivered high-energy lithium-ion cells that met the project’s specific energy goal and exceeded the project’s energy density goal. But Amprius’ cells did not meet the project’s cycle life goal, suggesting additional manufacturing process development is required. With DOE support, Amprius developed a new anode material, silicon, and a new anode structure, nanowire. During the project, Amprius also began to develop a new multi-step manufacturing process that does not involve traditional anode production processes (e.g. mixing, drying and calendaring).
