Leclanché has developed XN50, a lithium-ion battery cell featuring Echion Technologies’ XNO, a niobium-based, active anode material.

The cell provides integrators and OEMs with a differentiated battery option that outperforms existing chemistries in heavy-duty e-mobility, rail and marine applications.

Leclanché carried out stringent product development and verification to produce the cell, which is commercially available now.

XN50 delivers the benefits expected from the new XNO anode chemistry, including 50% higher energy density than LTO technologies, fast charging, and cell safety and performance in extreme conditions.

The XN50 cell can deliver high power over an estimated life of more than 10,000 cycles when used in heavy-duty applications, making it ideal for the rail, marine and mining sectors.

Studies show less than 3% capacity loss and lower than 15% resistance growth after 1,000 2C/2C charge/discharge cycles at 45 C.

Leclanché’s unique, water-based cathode formulation ensures the XN50 cell electrodes are PFAS-free, reducing environmental impact.

Pierre Blanc, chief executive officer at Leclanché, said: “XNO is soon set to displace the use of LTO within our product line and it will complement our current G/NMC offering as the go-to fast-charging battery solution for heavy-duty applications, and so we look forward to integrating XNO into our innovative module and pack systems.”
