TaiSan

TaiSan, based in Coventry and Cambridge, develops sodium-ion batteries for e-bikes, e-scooters and light EVs. Our polymer electrolyte technology gives packs that are 30% lighter and 25% more compact than lithium-ion, with 15-minute fast charging and improved safety. Packs come in a range of sizes and drop into existing vehicles without redesign. We have signed 15+ letters of intent with customers and are starting pilots with bike and scooter manufacturers in 2026, backed by €7m in funding. Our team brings 100+ years of combined electrochemistry experience from organisations including Jaguar Land Rover and SpaceX.
