Summary

UK battery materials startup TaiSan, operating from a Cambridge battery lab and founded by former Kazakhstani chess champion Sanzhar Taizhan, has successfully raised £4.65 million in a seed funding round. The company specializes in developing next-generation sodium batteries, which it claims are more efficient than current sodium-ion and lithium-ion alternatives. These batteries are intended for various applications, including electric bikes, scooters, vehicles, and power tools. The seed round was co-led by Eos Advisory and the Midlands Engine Investment Fund II, managed by Mercia Ventures, with additional participation from AFI Ventures, EverQuest Capital Partners, Adeline Arts & Science, Techmind, and existing investors like InnoEnergy. Notably, £700,000 of the total funding came from an Innovate UK grant. TaiSan plans to utilize this capital to advance its technology and initiate pilot tests with manufacturers, building on its previous €1.7 million pre-seed funding.

Key takeaway
