What are the differences between ternary lithium battery and lithium iron phosphate battery?

1. Which is the longer life of ternary lithium or lithium iron phosphate? The remaining capacity of the ternary material battery is 66% after 3900 cycles, and the remaining capacity of the lithium iron phosphate battery is 84% u200bu200bafter 5000 cycles. The cycle life is more obvious than that of the ternary material battery and lithium iron phosphate battery. According to the remaining capacity/initial capacityu003d80% as the end point of the test, the current 1C cycle life of the ternary material battery laboratory is about 2500 times, and the 1C cycle life of the lithium iron phosphate battery laboratory is more than 3500 times, and some of them reach more than 5000 times. 2. The energy density of a ternary lithium battery and a lithium iron phosphate battery is better. The energy density of a lithium iron phosphate battery is much different than that of a ternary lithium battery. The current subsidy standard for new energy vehicles uses the energy density of the battery pack system as an important indicator. It is stipulated that when the energy density of the battery system exceeds 120Wh/kg, you can enjoy 1.1 times the subsidy, and only 1 times the subsidy between 90Wh/kg and 120Wh/kg. It should be explained here that the energy density of the automotive power lithium-ion battery pack processed by Lilang battery has reached 125Wh/kg. The energy density of lithium iron phosphate batteries is usually between 90Wh/kg-120Wh/kg, while the energy density of ternary lithium batteries can reach about 200Wh/kg. It can be seen that the energy density advantages of ternary lithium batteries are clearer. In recent years, the reason why a large number of ternary lithium battery production lines have been launched in China, coupled with the persistence of Japan and South Korea in the direction of ternary lithium battery technology, has injected strong confidence into the market. Third, the safety of ternary lithium battery and lithium iron phosphate battery is better. We know that, as far as the material system is concerned, the decomposition temperature of the positive electrode material of the ternary lithium battery is about 200 ℃, and the decomposition temperature of the positive electrode material of the lithium iron phosphate battery is 700 ℃ around. In the laboratory test environment, short-circuit lithium iron phosphate battery monomers basically do not catch fire. This is not the case for ternary lithium batteries. Especially when using ternary lithium batteries, higher requirements for thermal management must be put forward. Regarding the vehicle battery pack, the safety measures are more complete and scientific. The lithium battery can be effectively managed through the BMS, and the battery can work in a safe state.
