Leclanché has been testing its 60Ah cells, based around a Water Based Binder (WBB) for the last year. These still use lithium ion and Nickel/Manganese/Cobalt for the electrodes with the WBB rather than a solvent based binder, making them more environmentally friendly to manufacture.

“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,” said Anil Srivastava, CEO, Leclanché.

The lifetime tests on the cells validate over 4000 cycles at 1C/1C continuous charging and discharging at room temperature and 30 minute fast charging. At the same time, the energy efficiency is stable and above 90% with minimal impedance increase. This is

“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.

The pouch cells are manufactured at Willstätt in Germany. Finished pouches are assembled into battery modules in Yverdon-les-Bains, Switzerland based on specific customer requirements

“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 Srivastava. “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.”

The G/NMC cells are used in applications such as the largest electric ferry, the Ellen, currently operating in Denmark. The company also makes LTO/NCA pouch cells for energy storage applications.
