AmpliSi develops a proprietary porous silicon anode material produced via a low-temperature process that converts abundant silica into porous silicon intended to replace graphite in lithium-ion batteries. The material aims to enable lighter, longer-lasting batteries for applications including electric vehicles and energy storage systems. The company was spun out of the University of Sheffield and co-founded with company builder Cambridge Future Tech, and is led by CEO Dr Ruth Sayers. AmpliSi holds intellectual and process know-how around its low-temperature conversion and porous silicon production. In March 2026 the company raised £2 million in a pre-seed round led by Northern Gritstone and Clean Growth Fund to fund industrial scale-up and early customer engagement.
