Through innovative models, SiPow effectively addresses market gaps, facilitating the exchange of new materials on an international scale."


SiPow, a spin-off of NanoPow AS, resulted from collaboration among experts in silicon recycling, Waste of Electric and Electronic Equipment (WEEE) photovoltaic, Nanosilicon production, and Battery Manufacturing. Over two decades, SiPow developed a method for producing crystalline nano-silicon powder for lithium-ion battery anodes. Their purified silicon enhances anode performance with ultrahigh specific capacities, surpassing traditional graphite anodes by tenfold. SiPow is revolutionizing the pure silicon market with breakthrough purification solutions and processes facilitating the trade of recovered raw material.

Methodology and Ambition

SiPow's purification process targets economic viability at an industrial scale, handling waste scraps from various PV technologies. SiPow's goal is to: 1) purchase low-purity recycled silicon from WEEE and WEEE photovoltaic recyclers; 2) purify silicon to meet market demand purity levels; and 3) supply purified silicon to users like nano silicon and lithium battery manufacturers. The innovative purification method is expected to reduce energy harvesting and costs with raw silicon from WEEE photovoltaic. SiPow's monocrystalline Pure Silicon aligns with industry demands, offering high energy capacity for new lithium battery-powered products, environmentally friendly solutions to limit CO2 emissions, and a high Return on Investment (RoI) for efficient energy independence.
