About Leclanché

Leclanché SA is a world leading provider of high-quality energy storage solutions based on lithium-ion cell technology. We are committed to accelerating our progress towards a cleaner energy future. We have over 100 years of battery and energy storage innovation, powered by German engineering and Swiss quality.

Our in-house technologies covering the full value chain

Our core technology expertise ranges from electrochemistry to energy management software. Leclanché develops, designs and manufactures complete battery storage solutions covering the entire technology chain from cells

to pack solutions for Hybrid Electric Vehicles (HEVs) and Battery Electric Vehicles (BEVs), as well as complete, energy storage solutions for utilities, grid operators and other large scale energy storage applications.


Leclanché engineers and manufactures its own cells which enables us to develop custom-designed solutions to meet the exact requirements of our customers. We also specify third-party cells when appropriate.

Modules / BMS

Modules & components are fitted into robust packs which can include air or water cooling systems as required. Battery management systems and switch boxes are also integrated within the pack ensuring fully self-contained energy storage systems.


Packs are adapted to operate faultlessly in the environmental conditions required by different systems or whatever the application: trains, buses, vessels and other electric vehicles; industrial; and grids and microgrids.

Marine Rack System

State-of-the-art battery storage system for marine applications. RINA and DNV-GL type approved; scalable in size, capacity and rated voltage; and fitted with liquid-cooling. Available with both water mist and foam-based fire suppression systems.


Leclanché's EMS software suite offers cutting-edge tools to manage large grid-connected battery energy storage systems (BESS). The EMS is designed with the flexibility for the integrating with multiple battery/inverter combinations.

Our solutions

Leclanché is reorganizing itself to become a green tech software and systems integration company with expanded production and R&D capabilities.

Our core operating units consist of Stationary Solutions, e-Transport Solutions and Special Battery Systems while an independent,

Build-Own-Operate projects business line has been established for selected Stationary Solutions projects with a long-term power purchase agreement and/or offtake agreement with local customers.

Battery and module production facilities are located in Germany and Switzerland.

Leclanché Stationary Solutions business group provides substantial benefits to grid operators, utilities and corporate and commercial energy users.

Leclanché’s e-Transport Solutions team powers the electrification of transport (trains, vessels, trucks and more) through efficient, proven and reliable energy storage solutions.

This group creates custom low-voltage battery systems for a wide range of demanding applications.

Our commitment

We're committed to respecting our environment, sustaining our communities, investing in our team and growing shareholder value.


Environmental awareness and concern for the future of our planet is in our DNA. It guides everything we do in our facilities, manufacturing processes and technologies. In our German plant, cell assembly starts with the electrode manufacturing exclusively using a water-based binder (WBB) process in an eco-friendly environment.

In comparison to organic solvent-based processes, Leclanché’s green manufacturing technology leads to minimal environmental impact, reduced end-cost of cell manufacturing and improved cell performance. Leclanché is one of the global leaders in applying the WBB technology. In addition our plant is solely powered by renewable energies.


At Leclanché, there’s no compromise on safety for our employees and the solutions we design. Leclanché has developed multi-level safety measures on a cell, module and system level – all tested and certified against mechanical, thermal and electrical abuse.

These include laminated ceramic separators and reduced electrolyte design in cells, IP 65 enclosures providing protection against electrical failure, battery management systems, cooling systems as well as best-in-class fire suppression systems.
