With the further development of electrolyte technology for battery systems, the British company TaiSan wins this year's start-up challenge organized by auto motor und sport in cooperation with Reziprok Ventures and heartfelt_. With this prize, the partners are supporting early-stage start-ups with innovative tech solutions for the energy and mobility transition with start-up funding of 100,000 euros.

The Cambridge-based start-up is developing innovative electrolyte polymers for batteries that work with sodium ions and thus offer many advantages over current lithium-ion systems: they do not require critical raw materials, are cheaper, safer, more environmentally friendly and more powerful at low temperatures. The polymer technology also makes the sodium-ion batteries more compact and lighter, which makes them interesting for a wide range of applications, including in the mobility sector.

"We are delighted to recognize a start-up that is working intensively on the handling of critical raw materials and offering alternatives," says Birgit Priemer, Editor-in-Chief of auto motor und sport. "This is crucial for the success and credibility of electromobility as a pioneering drive concept, including among customers." Marcus Willand, Managing Director at reziprok, has a similar view: "Heartfelt_ and reziprok ventures are particularly pleased to be able to honor a European start-up that comes from cutting-edge research. We want to send a clear signal that we in Europe are at the forefront of global innovation in the future of the automotive industry. The task now is to develop TaiSan into a European standard for quasi-solid-state sodium batteries."

The Start-up Challenge is a prize that was launched last year. The first winner in 2024 was the company LIMATICA with its innovative measurement method for the battery manufacturing process.
