Leclanché SA achieved a significant breakthrough in the safety of its lithium-ion batteries without compromising cell performance. By adding a special fire-retardant additive to its electrolyte formula composition, Leclanch- has lowered the risk of a thermal event by close to 80%. The achievement has been validated by Intertek Germany, a renowned third-party testing lab which conducted a series of industry standard nail penetration tests on Leclanch-'s 60Ah cell.

Despite the test cells being punctured with the resulting internal short circuit, the cells exhibited a far lower risk of fire than the same cells without the flame retardant additives. Non-flammable lithium-ion cells have major implications to users in the railroad, truck and bus markets, which are accelerating their investment in hybrid and all-electric powered fleets and who are concerned about the risk of fire with passengers aboard. Lithium-ion battery recalls are an expensive problem, let alone the disruption it causes to operations.

Leclanch- is one of the world's leading energy storage solutions companies.
