Taisan Motors Secures £3.2m Series A to Advance Quasi-Solid-State Sodium Batteries

London-based battery materials startup Taisan Motors Ltd has successfully closed a £3.2m Series A funding round. The transaction, which was allotted on 13 February 2026 and officially filed on 10 March 2026, brings the company to an estimated post-money valuation of £12.5m.

Incorporated in January 2022 and founded by Sanzhar Taizhan, Taisan Motors specialises in the development of quasi-solid-state sodium batteries tailored for the battery electric vehicle market. The company addresses the critical challenges of cost, safety, and supply chain vulnerability inherent in traditional lithium-ion energy storage. By engineering a proprietary polymer electrolyte and novel anode materials, Taisan aims to deliver batteries that match the energy density of current automotive lithium-ion cells while projecting a 20 percent reduction in costs.

Crucially, the startup's technology relies entirely on abundant and environmentally friendly materials. The chemistry eliminates the need for lithium, nickel, cobalt, and copper, substituting them with highly accessible alternatives like sodium carbonate. This approach not only lowers the initial capital expenditure for manufacturing but also mitigates the fire risks associated with conventional liquid electrolytes. The company currently operates with a lean team of five employees and focuses heavily on research and development, aiming to license its material designs directly to tier-one battery manufacturers and automotive original equipment manufacturers.

This £3.2m Series A round represents a substantial valuation increase for the business. It follows a £1.3m pre-seed round announced in July 2024, which was supported by a consortium of European strategic e-mobility investors including EIT InnoEnergy, TSP Ventures, Heartfelt VC, and Exergon. Before securing institutional venture capital, Taisan Motors also built its foundational technology through approximately £500k in non-dilutive grant funding. These early grants were awarded by prominent UK institutions such as Innovate UK, the Department for Transport, and The Faraday Institution.

The successful raise by Taisan Motors fits into a broader trend within the United Kingdom funding landscape, where deep tech and clean technology hardware startups are drawing targeted investment. The UK has placed a strategic emphasis on developing a domestic battery supply chain to support the transition to electric mobility. Alternative chemistries like sodium-ion are particularly attractive to investors and policymakers because they reduce reliance on volatile international mineral markets. With lithium carbonate historically subject to severe price fluctuations, the ability to utilise sodium carbonate at a fraction of the cost presents a compelling economic case for the automotive sector.

By securing this Series A capital, Taisan Motors is positioned to accelerate the testing and commercialisation of its quasi-solid-state technology, moving closer to integrating its sustainable battery materials into the next generation of electric vehicles.
