Novacium develops silicon-based anode materials for lithium-ion batteries, blending 10% silicon-oxide (SiOx) with graphite to boost energy density and maintain compatibility with existing manufacturing. Its Gen3 18650 cells deliver over 4,000 mAh capacity, 80% retention after 1,000 cycles, and 99.88% coulombic efficiency. Gen4 targets over 4,300 mAh. Additionally, Novacium has a patented process converting aluminum waste (black dross) into hydrogen feedstock.
Gen3 18650-size silicon-anode cells: >4,000 mAh, 80% capacity retention after 1,000 cycles, 18% higher capacity and 31% more energy output vs. traditional cells, 99.88% coulombic efficiency. Gen4 cells aim for >4,300 mAh. Anode blend: 10% SiOx with graphite. Applications include EVs, consumer electronics, unmanned drones, and tactical military communications.
In 2025, the company has officially begun industrial-scale output of cylindrical lithium-ion cells (18650 and 21700 formats) incorporating its GEN3 silicon-based anode material, a significant step up from previous lab and pilot phases. According to HPQ Silicon (Novacium’s partner and exclusive North American licensee), annual production capacity for HPQ ENDURA+ and/or NOVACIUM-branded 18650 lithium-ion cells is projected at up to 1.5 million cells.
In 2025, HPQ Silicon increased its stake from 20.0% to 28.4%, and the founders hold an equity position in HPQ. In 2023, the French Bank of Public Investments (BPI) awarded a €90,000 grant.
