Swiss energy storage leader Leclanché SA has introduced an advancement in the world of lithium-ion batteries with the launch of XN50, the first-ever battery cell incorporating a niobium-based active anode material.
“The company is “delighted to announce the launch of the world’s first commercial XNO Li-ion cell,” said Pierre Blanc, Chief Executive Officer of Leclanché. He emphasized that the XNO is on course to replace its current lithium-titanate-oxide (LTO) technology.
“It will complement our current G/NMC offering as the go-to fast-charging battery solution for heavy-duty applications,” he added.
This new XN50 battery technology integrates advanced materials from Cambridge-based Echion Technologies, a world leader in niobium-based active anode materials. The XN50 has been developed through rigorous product testing to meet high market demands, and according to Leclanché, the new battery delivers 50% better energy density than LTO technology while maintaining the ability to fast charge—key advantages for industries that operate in extreme conditions.
Further showcasing its durability, Leclanché’s XN50 cell can endure over 10,000 charge-discharge cycles with minimal power loss, boasting only a 3% capacity degradation over its lifetime. Additionally, the XN50’s resistance growth was measured at just 15% after 1,000 high-speed charge cycles at 45°C (113°F).
In terms of sustainability, the XN50 incorporates a PFAS-free, water-based cathode formulation, reducing environmental impact and adding to its appeal for companies aiming to reduce their carbon footprint. A study by Ghent University highlighted a 51% lower global warming potential when comparing the XNO materials used in the XN50 to traditional anode materials, marking a milestone in green energy solutions.
Jean de La Verpilliere, CEO of Echion Technologies said: “The Leclanché battery cell is setting a new standard for heavy-duty Li-ion batteries.” He expressed admiration for the Swiss company’s commitment, stating that their “exceptional drive, hard work, and expertise” have been key to this success.
The XN50 is designed for a wide range of industrial applications, including battery-electric and hybrid trains, mining trucks, opportunity-charging electric buses, and heavy-duty industrial transport. Leclanché and Echion look forward to seeing the battery’s large-scale deployment, with Verpilliere saying, “We look forward to seeing XN50 in the field at scale.”
Echion’s proprietary XNO materials, protected by thirteen international patents, are produced in thousands of tons annually, signifying their readiness for global commercial use.
Earlier this year, Echion completed its Series B funding round, securing $35 million to accelerate the widespread adoption of XNO technology in real-world applications.
