Maker of silicon-anode lithium-ion batteries offering high energy density for drones, aviation and EVs.
Maker of silicon-anode lithium-ion batteries offering high energy density for drones, aviation and EVs.
Sells cells and packs by the unit, with sales concentrated in a small number of drone and aerospace buyers, so a few customer orders move results. It builds premium low-volume batteries in its own California plant and also uses outside contract manufacturers for volume.
Moat: narrow (IP / patents, process know-how). Proprietary silicon-anode manufacturing process yields higher energy density than standard lithium-ion cells.
