TaiSan operates out of a Cambridge battery lab and develops next-generation sodium batteries it says are more efficient than existing sodium-ion and lithium-ion rivals. The company targets applications including electric bikes, scooters, vehicles and power tools. Founded and led by Sanzhar Taizhan, a former Kazakhstani chess champion, TaiSan has kept several breakthroughs in stealth while progressing its electrochemistry. Financially, the startup has raised €1.7M in pre-seed funding and has just closed a £4.65M seed round that includes a £700,000 Innovate UK grant. TaiSan plans to use the new capital to enhance battery performance and begin pilot testing with manufacturers. The company intends to bring its sodium-battery benefits to a mainstream audience.
