Develops FEST quasi-solid-state and Solstice all-solid-state batteries for vehicles, drones, robots, and energy storage, while using Gammatron software to support battery development and operation. Revenue is intended to come through licenses, development work, materials, and battery-cell sales, with industrialization centered on manufacturing partners.
Develops FEST quasi-solid-state and Solstice all-solid-state battery platforms for road vehicles, drones, mobile robots, and energy storage. Gammatron, its digital-twin platform, supports electrolyte development, cell-health modeling, fast-charge optimization, battery-management systems, and production traceability.
Works with automakers, integrators, suppliers, and manufacturing partners to develop, sample, validate, and industrialize those systems. Research, testing, and low-volume production are based in Massachusetts; most current cell-production capacity is in South Korea, with partner-facing activity across Europe and Asia.
Relies on capital-light joint manufacturing rather than a wholly owned mass-production footprint. The business remains pre-revenue, while commercial-scale production depends on technical qualification, partner conversion, third-party capacity, materials supply, and battery safety and cross-border regulations.
