Lithium batteries, although small in size, have high energy, and they also contain a flammable electrolyte. If the energy is good, the energy is a high-efficiency energy source, and if the energy is bad, a large amount of heat can be generated to cause combustion, and even disasters are formed. An electric energy of a lithium cobalt 18650 ion battery with a capacitance of 2-3Ah has 25-40KJ, and the heat generated by chemical reaction after combustion can reach 280KJ.
