Description

technical field [0001] The invention relates to the technical field of fireproof materials, in particular to a new energy vehicle battery fireproof material and a manufacturing method thereof. Background technique [0002] With the development of society and the progress of science, the energy sources of automobiles are becoming more and more diversified. Now there are new energy vehicles such as hybrid electric vehicles and pure electric vehicles. During the use of new energy vehicles, the heat generated by the chemical reaction inside the battery The rate is much higher than the heat dissipation rate, and a large amount of heat accumulates inside the battery, causing the battery temperature to rise rapidly, or after being punctured, it will cause the battery to catch fire or explode, resulting in thermal runaway of the battery. After the battery thermal runaway, there will be flames, causing fire and casualties. [0003] Existing new energy vehicle batteries are often cov...
