Swiss energy storage pioneer Leclanché SA has introduced the XN50, the world’s first lithium-ion battery cell that utilizes a niobium-based active anode material. This innovative battery technology is designed specifically for heavy-duty transport applications, including e-mobility, rail, and marine sectors. According to CEO Pierre Blanc, the XN50 will replace the existing lithium-titanate-oxide (LTO) solutions in their product line, offering faster charging capabilities and improved performance, particularly in harsh conditions.

The XN50 boasts a 50% increase in energy density compared to LTO technology and is expected to have a lifespan of over 10,000 charge cycles. The battery is engineered to maintain high power output, with less than three percent capacity loss even after extensive use. Its performance metrics include a modest resistance growth of 15% after 1,000 cycles at elevated temperatures. Moreover, the XN50 employs a PFAS-free, water-based cathode formulation, significantly reducing its environmental impact.

Echion Technologies, based in Cambridge, has played a crucial role in the development of the XN50, providing the niobium-based anode materials. The company has seen recent success, winning the Tech Scale-Up category at the Business Weekly Awards, and their XNO materials are produced at scale under strict international patents. A study from Ghent University highlighted the substantial environmental benefits of XNO, marking it as a preferable alternative in terms of global warming potential.

The XN50 is set to revolutionize energy storage, particularly in industrial and mass transportation applications. It is poised for use in battery-electric and hybrid trains, mining haul trucks, and e-buses, among others. With substantial funding raised earlier this year, Echion is positioned to ensure widespread adoption of this advanced technology, setting new standards for heavy-duty lithium-ion batteries and paving the way for sustainable energy solutions.
