The selected extinguishing gas or gas mixture smothers the fire source by displacing oxygen. Inert gases therefore provide residue-free extinguishing. This eliminates the consequential damage caused by the use of water-based, powder or aerosol extinguishing agents. Inert gases do not form chemical compounds in common fire scenarios.
As lithium battery fire is a deep fire, TR will release a large amount of gas, making it difficult for gaseous extinguishing agents to enter the interior of the battery, so in the suppression of lithium battery TR, gaseous extinguishing agents can effectively extinguish the flame, but cannot prevent the continuation of the TR reaction inside

It is well known that Lithium-ion batteries in thermal runaway can emit gases with high hydrogen concentrations which, in case of delayed ignition, can cause a gas explosion. Aerosol suppression agents are sometimes used to suppress fires and/or prevent ignition of released gases in such situations. The agent has been studied for suppression of fires

The operating principle is simple: the extinguishing gas removes the basis of a fire. Either the extinguishing gases suffocate the source of the fire by displacing oxygen from the environment (inert gases). Or they extract the necessary heat energy from the fire (synthetic extinguishing gases). This stops the fire from spreading at a very early
It was found that this in-situ fire-suppressing technology can effectively inhibit the flame of the ternary Li-ion battery (NCM18650) and control the temperature below 130°C.
