Sells silicon-anode lithium-ion cells and custom battery designs for drones, aviation, defense, and light electric mobility. SiCore supplies most commercial volume through global contract manufacturers, while SiMaxx centers on proprietary nanowire anodes and Fremont supports R&D and pilot work.
Develops and sells silicon-anode lithium-ion cells for aviation, defense, drones, light electric vehicles, and other mobility uses. SiCore spans pouch, cylindrical, and prismatic formats built for high energy, high power, or longer cycle life; SiMaxx uses a proprietary silicon-nanowire anode for especially weight-sensitive applications. Custom battery design and prototype work supplements product sales.
Demand is international, with Europe, the Middle East, and Africa supplying most recent revenue and North America and Asia-Pacific also contributing. The commercial model pairs rapid product tailoring and multiple cell formats with outsourced scale production. SiCore supply relies on Berzelius materials and global contract manufacturers, including partners in South Korea, while Fremont houses R&D and the expanding pilot line.
