Amprius has taken on one of technology's toughest problems—improving battery life. It's an issue that affects mobile computing, electric vehicles and many other products. Conventional Lithium Ion material systems—in particular, anodes and cathodes—have been slow to evolve. Using silicon to replace conventional carbon anodes, Amprius increases battery density by up to 10x. Amprius is producing batteries at scale for phones, tablets, drones and electric vehicles.
