Leclanché SA stands as a prominent Swiss provider of energy storage solutions, specializing in advanced lithium-ion cell technology. Since its establishment in 1909, the company has maintained a steadfast commitment to innovation in battery development and energy storage systems. With over a century of expertise combining German engineering and Swiss precision manufacturing, Leclanché develops and manufactures custom energy storage solutions for various industries, including transportation, utilities, and industrial applications. The company’s integrated approach covers the entire value chain, from cell design and production to complete system integration, positioning it as one of the few fully vertical manufacturers in the energy storage sector.
Battery Technology
Leclanché’s technological portfolio centers on proprietary lithium-ion cell designs and manufacturing processes. The company’s latest achievement includes the XN50, an innovative lithium-ion cell utilizing niobium-based active anode material. This advancement offers superior energy density and fast-charging capabilities compared to traditional lithium titanate oxide (LTO) technologies.
The company’s manufacturing process employs a unique water-based manufacturing technique, eliminating toxic organic solvents typically used in battery production. This method has enabled Leclanché to reduce cobalt content in their G/NMCA cells to just 5% while increasing energy density by 20%. Their M3 module generation serves high-energy and power applications in e-transport, featuring advanced thermal management and safety systems.
Leclanché’s battery management systems (BMS) incorporate sophisticated monitoring and control functions, ensuring optimal performance and longevity. The company’s energy management software provides real-time analytics and control capabilities for large-scale installations, enabling efficient operation of battery storage systems across various applications, from maritime vessels to grid storage solutions.
Recent Projects
In early 2024, Leclanché secured a significant partnership with Pinnacle International Capital, potentially providing up to CHF 360 million in funding. The company also completed installation of a battery storage system at Veolia’s gas power plant in Slovakia, demonstrating its capabilities in industrial-scale energy storage solutions.
A notable development includes the introduction of PFAS-free and niobium oxide cells, reinforcing the company’s environmental commitment. Leclanché’s marine division is actively showcasing its electrification solutions at the 2024 Electric Hybrid Marine Expo Europe in Amsterdam, expanding its presence in the maritime sector.
