Leclanche 60 Ah Cell Shows Promise in Automotive Charging ApplicationsDecember 29, 2020 by Nicholas St. John
After year-long testing, Lechlancé’s new battery cells have shown very promising results for applications in the automotive and e-transportation industries.
Lechlancé, a company headquartered in Switzerland with offices in Germany as well, produces high-quality energy storage solutions with the goal of creating a clean energy future, has recently presented test results of their new 60Ah cells that have both fast-charging and long-range capabilities. These two features coupled with one another are obviously an ideal fit for electric vehicle (EV) applications, and the test results prove great capability in both of these areas from the cells. The presentation was given by Dr. Petronela Gotcu and Dr. Hilmi Buqa, manager of R&D Cells and vice president of R&D Cells respectively according to their press release, and the results can be seen here.

There are two types of cells that Lechlancé is producing right now, one having a Graphite anode paired with a Nickel Manganese Cobalt cathod (G/NMC) while the other has a Lithium Titanate anode paired with a Nickel Cobalt Aluminum Oxide cathode (LTO/NCA). The G/NMC battery is made for more energy intensive applications, while the LTO/NCA configuration has leading performance in long-life and rapid charge applications.
Looking into the report, there are a few key takeaways from the tests:
- Battery efficiency is very high and stable (over 90%)
- At a charge rate of 1C and discharge rate of 1C (1C/1C continuous cycle), the cells are verified from lifetime tests to hold up for over 4000 cycles. This test had a 100% Depth of Discharge (DoD), which means 100% of the battery capacity is depleted before charging again at room temperature.
- For the G/NMC cell, stable cells cycled between 3.00 - 4.35V showed a 10% capacity increase compared to current G/NMC cells in industry currently
- This will result in lower cost of the battery pack for EVs
As stated previously, Lechlancé makes clean energy and the environmental impact of their work a top priority. Mostly in the cell manufacturing process, companies use an organic solvent-based process, while Lechlancé uses their world-leading water-based binding (WBB) process that is much more eco-friendly. This green technology manufacturing process not only minimizes environmental impact, but also reduces the end cost of the cell and improves their performance. The finished battery pouches are then assembled into battery modules in Switzerland and are custom made to fit the specifications given by the customer.
These test results are just the beginning of these battery cells that will find their homes in the future of EV and e-transportation fields as the world economy continues to shift more towards green and electric-based technology. The novel technology shown in these tests and the green manufacturing process put into place by Lechlancé will set a standard as this industry continues to shift and grow.
