GAME-CHANGING PERFORMANCE
Highest Energy Density Rechargeable Lithium-ion Batteries in the World
Amprius Technologies, Inc. is at the forefront of transforming electric mobility with its revolutionary silicon anode lithium-ion battery. The Company’s batteries deliver unmatched performance – ultra-high energy density, high power density, extreme fast-charge rate capability, and wide operating temperature – required for aviation, aerospace, defense, and electric vehicles (EV).
Amprius’ commercially available batteries deliver up to 450 Wh/kg and 1,150 Wh/L, the industry’s highest known energy density cells available on the market today. The cells leverage a customizable platform, allowing customers to either increase energy content in a battery pack without increasing weight, to reduce weight in applications that target a fixed energy content, or combinations of both.
Independent third parties and large reputable companies have verified the battery performance and safety. Based on Amprius’ current level of battery performance and pilot production, the Company will be able to use its proprietary anode technology to deliver battery cells that contain energy density levels that approach 2x the performance of current commercially available graphite cells.
The Company’s corporate headquarters is in Fremont, California where it maintains an R&D lab and a pilot manufacturing facility for the fabrication of silicon anodes and cells. To serve significant customer demand for its high-performance silicon anode lithium-ion batteries, Amprius recently signed a lease agreement for an approximately 774,000 square foot facility in Brighton, Colorado that initially provides a potential of up to 5 gigawatt-hours (GWh) manufacturing capacity.
A Strategic Energy Partner for Next-Gen Defense Systems
Enovix Corporation is a strategic energy partner pioneering next-generation lithium-ion battery technology for critical defense, aerospace, and advanced electronic applications. The Company’s high-performance batteries deliver unmatched energy density, high thermal efficiency, and robust continuous discharge capabilities—engineered to power modern soldier-worn equipment, autonomous aerial vehicles, and uncrewed maritime systems.
Enovix leverages proprietary cell architectures, including 100% active silicon anodes and durable silicon-graphite (Si-Gr) blends, to enable industry-leading performance. Key product platforms include Specter (608 Wh/L) for lightweight tactical optics and AR headsets; Hooper (733 Wh/L), developed in partnership with the U.S. Army Central Wearable Battery (CWB) program for vest-integrated power; Red Tail, delivering up to 30C continuous and 45C pulse discharge rates for high-power drone propulsion; Magpie, yielding 800 Wh/L and 360 Wh/kg for maximum aerial endurance; and Leviathan, a 105 Ah subsea-grade cell built for 6,000 cycles at deep ocean pressures.
To ensure supply chain security for defense partners, Enovix operates an NDAA-compliant, non-China global footprint. Headquartered in Silicon Valley, California, with advanced material R&D in Hyderabad, India, Enovix manufactures high-durability cells at its 400,000+ sq. ft. facility in Nonsan, South Korea, and is scaling high-volume 100% silicon production at its ISO 9001-certified Fab2 facility in Penang, Malaysia. With over 20 years of defense sector involvement and strong financial backing (~$648 million in liquid assets), Enovix delivers end-to-end battery co-development and mass production tailored for mission-critical operations
