Are ternary lithium-ion batteries more prone to spontaneous combustion than lithium iron phosphate batteries?

According to the internal structure of the power lithium battery, the lithium ion battery is composed of four parts: positive electrode material, negative electrode material, barrier and electrolyte, while the lithium iron phosphate battery uses lithium iron phosphate as the positive electrode material. . The ternary lithium-ion battery is a lithium-ion battery that uses nickel-cobalt manganate lithium ion ternary positive electrode material. The ternary lithium-ion battery and the lithium iron phosphate battery have different characteristics, and the main focus is on energy density. . The energy density of ternary lithium ion batteries is greater, and although the energy density of lithium iron phosphate batteries is small, the energy density is more vivid for the internal lithium. The lithium iron phosphate battery has a low energy density relative to the ternary lithium ion battery. According to the nature of the battery's internal data, although the lithium iron phosphate battery is resistant to high temperatures, although the materials of these two electrodes will reach a certain temperature Internal decomposition occurs, but according to the ternary lithium ion data, the battery uses a non-aqueous electrolyte solution. The chemical characteristics of lithium-ion metal after encountering heat are very vivid. The heat-resistant temperature of a battery is basically about 200 degrees, and when the temperature reaches the heat-resistant temperature, the chemical reaction of the ternary lithium-ion material will be more Severe, the electrolyte burns quickly under the effect of high temperature. The heat-resistant temperature of the electrode material of lithium iron phosphate is 500-800 degrees, which does not release oxygen molecules like the ternary lithium ion material, and the incineration is not so violent. The materials of lithium iron phosphate will not be burned when encountering a short circuit, and the high temperature performance is much better than that of ternary lithium ion batteries.
