YVERDON-LES-BAINS, Switzerland, 4th November 2020 – Year-long testing of Leclanché SA (SIX: LECN)’s 60 Ah G/NMC battery cells has proven them to be both high energy density and high life cycle, critical characteristics for a wide range of automotive and e-transportation energy storage solutions.
The presentation of results was made by Dr. Petronela Gotcu, manager R&D Cells and Dr. Hilmi Buqa, vice president R&D Cells, Leclanché, at the International Battery Production Conference 2020 Braunschweig, Germany, held online this year from November 2 – 3. A poster with the results, presented at the conference, can be viewed at this link. Leclanché is one of the world’s leading energy storage companies.
Key findings include:
Leclanché Cells Manufactured Using Green, Water-Based Technology
Leclanché offers two kinds of rechargeable lithium-ion cells: G/NMC cells for energy intensive applications, and LTO/NCA for leading performance in long-life and rapid charge applications. Both cell types are produced in a pouch format in the company’s Willstätt, Germany manufacturing facility.
Its 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 the cell manufacturing and improved cell performance. Leclanché is one of the global leaders in applying the WBB technology. Finished pouches are assembled into battery modules in Yverdon-les-Bains, Switzerland based on specific customer requirements.
“These research findings validate that Leclanché can now offer next generation, high energy density and high life cycle cells which support both long-range and fast-charging battery applications, a key requirement of the automotive and e-transportation industries,” said Pierre Blanc, chief technology and industrial officer, Leclanché.
Automotive and e-Transportation Commercialization Opportunities
The path to a potential mass market application of its technology started back in 2008 with investments of CHF 250 million and more than a decade of in-house research and development and more than 200 patents. The company’s storage solutions have already been implemented in a broad array of maritime industry vessels, hybrid railroad locomotives and other specialized vehicles.
“We are now adding a new strategic growth area to our business by leveraging our high energy density and fast charging 2C G/NMC cells. We bring to market 100% inhouse cell technology developed in Europe, combined with the valuable knowhow gained from more than eight years of large-scale production in our factory in Willstätt, Germany. This sets Leclanché apart from the bold and aspirational announcements based on technologies imported essentially from Asia,” said Anil Srivastava, CEO, Leclanché. “We are in the process to federate Leclanché technologies to enable large scale production of cells. Currently we are in active discussions with strategic parties to license Leclanché technologies to set up large-scale automotive battery cell production facilities in Europe.”

 Ah: Ampere hour is the rating used to tell consumers how much amperage a battery can provide for exactly one hour.
 A C–rate is a measure of the rate at which a battery is charged/discharged relative to its maximum capacity. A 1C rate means that the charge/discharge current will charge/discharge the entire battery in 1 hour.
 Depth of Discharge (DoD) is the fraction or percentage of the capacity which has been removed from the fully charged battery. It is an alternative method to indicate a battery’s state of charge.
