TaiSan, a UK battery technology company developing solid-state sodium-ion batteries, has raised £4.65 million to accelerate product development and prepare for pilot projects with leading manufacturers.
The round was co-led by Eos Advisory and the Midlands Engine Investment Fund II, managed by Mercia Ventures, with participation from AFI Ventures, EverQuest Capital Partners, Adeline Arts & Science, Techmind, angel investor François Badelon, existing investors, and Innovate UK, which contributed £700,000 through its Investor Partnerships Programme.
Expanding Sodium-Ion Battery Applications
TaiSan has developed a proprietary solid-state electrolyte that enables sodium-ion batteries to be lighter, more compact, and safer than conventional sodium-ion and lithium-ion alternatives. The technology is designed for applications including electric bikes, scooters, electric vehicles, power tools, and other portable devices.
The funding will support pilot testing with manufacturers, laboratory expansion in Cambridge, and the establishment of new operations in Coventry. The company has also secured several letters of intent from prospective customers.
Scaling for Future Growth
Founded by former Jaguar Land Rover and The Faraday Institution researcher Sanzhar Taizhan, TaiSan aims to expand the commercial use of sodium-ion batteries through a capital-efficient business model while addressing growing demand for safer and more sustainable energy storage solutions.
