Experimental study on fire extinguishing of lithium-ion batteries and fire protection of cardboard based on novel multiphase material
In order to resolve the problems of difficult fire extinguishing and easy re-ignition of lithium-ion battery fire,a no-vel multiphase material was developed and prepared.The material was used in the experiments of fire extinguishing of lithium-ion battery and the fire protection of typical combustible cardboard,and the fire extinguishing and fire protection performance of the material were investigated by the parameters such as fire extinguishing time,cooling rate,and ignition time of card-board.The results show that the novel multiphase material can quickly extinguish the open fire generated by the thermal runa-way of Li(NiCoMn)O2 lithium-ion batteries and LiFePO4 lithium-ion batteries,and inhibit their re-ignition.It can also prevent the white cardboard under open fire from burning,and it has excellent fire extinguishing and fire protection performance.The research results can provide a new and efficient fire extinguishing agent for the initial fire fighting and disposal of lithium-ion batteries.
