Presentation Summary

There is an inherent conflict between energy density and safety in conventional Li-ion battery structure, so that improving one usually adversely affects the other. Enovix Corporation has developed a Li-ion battery with 3D cell architecture that improves spatial efficiency, accommodates a high-capacity silicon anode, and reduces the risk of thermal runaway. This significantly increases energy density and improves safety. Enovix will describe its patented 3D cell design its low-cost, high-volume production process.

Speaker Biography (Jerald Hallmark)
