Charged EVs | Leclanché publicizes breakthrough in security of its battery know-how with fire-retardant electrolyte additive


Swiss battery supplier Leclanché says it has achieved “a major breakthrough” within the security of its lithium-ion batteries, with out compromising cell efficiency.

By including a particular fire-retardant additive to its electrolyte formulation composition, Leclanché says it has lowered the danger of a thermal occasion by near 80%. The achievement has been validated by Intertek Germany, a third-party testing lab which carried out a collection of nail penetration exams on Leclanché’s 60 Ah cell. The check cells had been punctured, and an inner quick circuit resulted, however they exhibited a far decrease threat of fireside than the identical cells with out the flame retardant components.

Leclanché’s cells are made utilizing a proprietary manufacturing course of. Electrodes are manufactured utilizing a water-based course of quite than through the use of natural solvents reminiscent of NMP, which the corporate says leads to a considerably diminished environmental footprint. Leclanché says its electrodes present excessive stability in the direction of the flame retardant components contained within the new electrolyte, and cell efficiency is uncompromised.

“Whereas the battery trade continues to put appreciable R&D sources into the event of solid-state batteries, there’s a important want to reinforce the protection of right this moment’s high-energy-density lithium-ion cell know-how,” stated CTO Pierre Blanc. “Most efforts, till now, adversely affect the efficiency or longevity of cells. Leclanché has been capable of develop a high-performance and high-energy-density lithium-ion cell exhibiting excessive security traits with none adverse affect on efficiency or longevity.”

“Our breakthrough ought to encourage producers ready on the sidelines for next-generation solid-state batteries to maneuver ahead with their superior fleet automobile designs right this moment,” stated CEO Anil Srivastava. “Protected lithium-ion batteries have arrived, and Leclanché has them.”

The corporate’s new non-flammable cells shall be out there for manufacturing starting within the first quarter of 2023.
