Dr. Ruth Sayers is CEO of AmpliSi, a University of Sheffield spinout pioneering next-generation porous silicon anode materials to replace graphite in lithium-ion batteries for EVs and grid-scale energy storage.

Ruth earned her doctorate in solid oxide fuel cells at Imperial College London in 2010, winning the prestigious John Kilner Prize for Energy Materials, before spending over a decade at Sheffield-based battery pioneer Faradion.

With deep expertise spanning battery chemistry, supply chain operations, and technology commercialisation, Ruth is focused on building scalable, safe, and cost-effective battery materials that integrate seamlessly into existing manufacturing lines.

Prior to AmpliSi, Ruth rose from Research Scientist to Director of Technology and Operations at Faradion, a sodium-ion battery company that was acquired by Reliance Industries for £100 million in 2021.

AmpliSi secured £2 million in pre-seed funding co-led by Northern Gritstone and Clean Growth Fund, and is now advancing from lab validation to industrial scale-up, targeting higher energy density and faster charging for the global EV market.
