Full Circle Lithium Corp. reported on the latest third-party testing results of its lithium-ion battery fire fighting agent. An independent US-based accredited third-party laboratory conducted a series of tests utilizing different size lithium-ion batteries including a collection of 19 NMC 2800 mAh (milliampere-hour) battery cells, a 960 Wh (watt-hour) electric bike battery (made up of 48x18650 NMC cells), and, most recently an electric vehicle ("EV") size 57 kW (kilowatt-hour) battery.

The third-party laboratory reported on the first two test results and will report on the EV size battery test after all internal analyses and comparisons are completed. Uncontrollable lithium-ion battery fires are proving to be a growing critical risk and challenge worldwide given the continued growth of electric lithium-ion battery-powered devices as well as for e-mobility and energy storage systems. The purpose of the third-party testing was to compare and understand the effects of different extinguishing agents on secondary lithium-ion batteries undergoing thermal runaway. The testing protocol was developed by a third-party laboratory to replicate current industry standards for lithium-ion propagation testing as well as fire suppression certification testing outlined in UL 9540A 4th edition and UL 711 8th edition.

While all three agents (the FCL Agent, water, and the leading third-party fire-fighting agent (the "Third-Party Agent")) mitigated the initial fires, the FCL Agent was orders of magnitude faster to extinguish the fires with only one application applied and produced considerably less volume of smoke (which contain hazardous chemicals).
