Amprius Technologies, Inc. (NYSE: AMPX) is a U.S.-based manufacturer of lithium-ion batteries that specialize in silicon anode technology, sold under its SiCore and SiMaxx product platforms. The company targets mobility applications, with a primary focus on aviation segments such as unmanned aerial systems (drones) and high-altitude pseudo satellites (HAPS), an emerging market for electric flight and aerospace propulsion. Founded in 2008 and headquartered in Fremont, California, Amprius went public in September 2022 and is classified within the GICS Industrials sector under Electrical Components & Equipment, reflecting its position as a mid-cap supplier of advanced energy storage components rather than a finished-vehicle or consumer electronics producer.
- Silicon anode battery orders accelerate from aviation and defense customers
- Manufacturing scale-up pressures margins ahead of unit cost reductions
- Capital raises and dilution fund capacity expansion into eVTOL and HAPS markets
