Amprius is a US battery maker (NYSE:AMPX) whose SiMaxx cells reach 450Wh/kg commercially (500Wh/kg third-party validated), the highest energy density commercially available, with FY25 revenue of $73M growing to a Q1-26 $28.5M (+153%) and FY26 guidance raised above $130M at a positive gross margin. Its core revenue is drones and UAS (including defense; a DIU contract expanded 3x to $18.1M, plus a Matternet partnership), and management explicitly targets humanoid robotics next. Robot and humanoid revenue is not yet broken out, so its power-layer candidacy is forward-looking, drone-proven chemistry.
