AmpliSi, a University of Sheffield spinout addressing the critical limitation in today’s lithium-ion batteries, has raised a £2m pre-seed funding round, led by Northern Gritstone and Clean Growth Fund.

Its proprietary porous silicon anode material is designed to replace graphite used in conventional batteries. This enables lighter, longer-lasting batteries for a range of applications, including EVs and energy storage systems.

The company aims to target the mobility sector, addressing demand for electric-vehicle batteries with higher energy density.
