Leclanché Introduces Niobium-Based Battery Cells for Industrial and Heavy-Duty EV Applications

Leclanché

Swiss energy storage company Leclanché is set to launch a new battery cell solution that leverages XNO, a niobium-based anode material developed by UK-based Echion Technologies. The XN50 battery cell will replace Leclanché’s current lithium titanium oxide (LTO) offering, with a focus on heavy-duty electric vehicles (EVs), rail, and marine applications.

The XN50 promises significant advancements over LTO cells, delivering 50% higher energy density and the ability to fast charge in under 10 minutes. Moreover, the niobium-based cells offer enhanced safety and performance, particularly in extreme weather conditions. These new cells will be available alongside Leclanché's existing nickel manganese cobalt (NMC) batteries, which use graphite anodes. Leclanché has been producing LTO cells since 2012 and introduced NMC batteries in 2019.

Niobium’s Growing Role in Battery Technology

Niobium, traditionally used in steel alloys and defense applications, is now becoming a key material in battery and fuel cell technologies due to its high energy density. Echion’s XNO materials, developed from mixed niobium oxide compounds and microparticle designs, are sourced from Brazilian niobium producer CBMM. The XN50 is the first battery cell to incorporate XNO on a commercial scale, offering manufacturers a cutting-edge solution for industrial and mass transportation use. Additionally, Echion has signed a deal with Taiwanese battery manufacturer GUS Technology to supply XNO for heavy-duty EV battery production.

As demand for niobium-based anode materials continues to rise, Echion plans to open a 2,000 t/yr XNO manufacturing facility this year to supply major cell manufacturers and original equipment manufacturers (OEMs). The versatility of niobium extends beyond batteries, with Canadian project developer NioBay Metals currently exploring niobium-titanium alloys for hydrogen fuel cells, presenting new market opportunities for niobium and titanium.
