The world’s leading developer of niobium-based, fast-charging battery materials.
Echion has devised and patented new materials that enable lithium-ion batteries to charge safely in less than 10 minutes with a long cycle life, ensuring extended use.
Its niobium-based anode material, XNO®, has an important role to play in electrifying heavy duty transport and industrial applications such as rail, high-powered off-road vehicles and fleets of trucks, buses and delivery vans.
“Our ambition is to deliver the best fast-charging batteries to unlock the electrification of heavy-duty vehicles. The entire team has worked tirelessly to develop our flagship XNO® material into what it is today.”

A more sustainable battery with XNO®
Suited for industrial, commercial, and high-value applications that demand the highest up-time, lowest total cost of ownership, and highest safety, XNO® enables lithium-ion batteries that can safely charge in less than ten minutes, maintain high energy densities even at low temperatures, and deliver high power across a cycle life of more than 10,000 cycles.
A spinout from the Department of Engineering, Echion’s academic founders Jean de la Verpilliere, Dr Alexander Groombridge, Professor Michael De Volder and Professor Adam Boies are now at the forefront of the British battery industry and deep tech innovation. Applications powered by XNO® include battery electric and hybrid trains, mining haul trucks, opportunity-charging e-buses, heavy-duty industrial transport and delivery vehicles. Echion XNO® materials are based on proprietary mixed niobium oxide compositions and microparticle designs protected by 13 international patent families and are now being scaled up to the multi-thousand tons/year production scale.
Having invested in Echion from its early stages, Cambridge Enterprise also participated in their 2024 £29 million Series B funding round, which will enable Echion to execute its go-to-market strategy to see its innovative material utilised in real-world applications, at volume.
