Amprius

The Highest Energy Density Lithium-ion Batteries in the World. Amprius Technologies’ batteries deliver up to 100 higher energy density than standard lithium-ion batteries. This means our cells provide more energy and power with much less weight and volume. Founded in 2008, Amprius Technologies is a pioneer and the established leader in the production of silicon anodes for high energy density lithium-ion batteries. Setting a precedent for scalable silicon anode production, Amprius developed a unique manufacturing process to grow 3D structures in a roll-to-roll system.
