AmpliSi Ltd.

AmpliSi Ltd. , based in the UK, focuses on developing innovative porous silicon anodes to enhance battery performance, aiming to meet the growing demands of the electric vehicle sector. AmpliSi Ltd. , located in Sheffield, UK, specializes in advanced battery technology through its development of high-performance porous silicon anodes.

Founded in 2025, founded by Dr. Gwen Chimonides and Professor Siddharth Patwardhan, the company raised GBP 2 million in pre-seed funding in March 2026, co-led by Northern Gritstone and Clean Growth Investment Management. This funding is aimed at scaling their technology for industrial production. Though no pivots or subsidiaries are noted, AmpliSi's sole focus on silicon anodes marks its distinct approach in the energy sector.

AmpliSi specializes in the development of high-performance porous silicon anodes designed to enhance battery technology by replacing traditional graphite anodes. The company employs a proprietary low-temperature, silane-free magnesiothermic process to transform abundant silica into these advanced anode materials. This innovative technology allows for higher energy density, faster charging, and lighter batteries, meeting the growing demands of electric vehicle (EV) manufacturers. The products are positioned primarily in North America, Europe, and select markets in Asia, where the push for electric mobility and sustainable energy solutions is accelerating.

AmpliSi's revenue model is centered on B2B transactions, primarily through partnerships with manufacturers and research institutions that integrate their silicon anode materials into existing production lines. The company engages in structured agreements that facilitate the adoption of their technology, optimizing battery performance while reducing costs. The porous silicon anodes can reduce costs by 30% per kilowatt-hour, suggesting a competitive pricing strategy aimed at encouraging adoption among EV manufacturers. The flagship product, the porous silicon anode, is designed to deliver long-lasting performance and sustainability.

In March 2026, AmpliSi Ltd. raised GBP 2 million in funding to move its technology toward industrial-scale production, refine its manufacturing approach, and start engaging with commercial partners and customers. The company plans to deploy this funding to support the development of upcoming products designed for the electric vehicle market, as well as to explore expansion into new geographic markets including Asia and North America, bridging into regions experiencing increased demand for sustainable energy solutions.
