AmpliSi is a University of Sheffield deeptech spinout developing scalable, sustainable porous silicon anode materials to replace graphite in lithium-ion batteries. Using a patented low-temperature, silane-free magnesiothermic process, AmpliSi converts abundant silica into high-performance porous silicon anodes that deliver superior energy density, longer battery life, and faster charging for electric vehicles and grid-scale energy storage, all while integrating into existing battery supply chains.
