Abstract

The present disclosure discloses a safeguard agent and a use thereof. The present disclosure provides a safeguard agent consisting of component A and component B, and the molar ratio of the component A to the component B is 1:(1-4). The safeguard agent in the present disclosure can cool the protected space and heat sources, physically isolate heat sources, prevent burning or extinguish the flame in the space, suppress explosion, and effectively and continuously suppress and prevent reignition. Using the safeguard agent of the present disclosure as a suppression agent for battery thermal runaway can achieve the purpose of terminating thermal runaway after cooling, antiflaming, suppression, or extinguishing of a battery in thermal runaway, and more batteries can achieve constant voltage and good appearance without damage phenomena. For other batteries affected by heat in the space, the safeguard agent can also effectively prevent or suppress potential thermal runaway.
