Which ternary lithium ion battery or iron phosphate lithium ion battery has a longer service life?

Lithium iron phosphate batteries and ternary lithium-ion batteries are widely used in electric vehicles. However, due to the impact of energy ratio and policy, the two important models are different. Lithium iron phosphate battery packs are mainly used for long-distance vehicles such as buses and large buses. The ternary lithium-ion battery is usually installed in a family car because its energy is approximately twice that of a lithium iron phosphate battery with the same capacity. After a brief understanding of lithium iron phosphate and ternary lithium ion batteries, let us return to lithium iron phosphate and ternary lithium ion batteries, which one is more durable? Lithium iron phosphate and ternary lithium ion battery life iron phosphate The remaining capacity of the lithium-ion battery 5000 cycles is 84%, and the remaining capacity of the ternary lithium-ion battery 3900 cycles is 66%. If the remaining capacity/initial capacityu003d80% is used as the end point of the test, the current cycle life of 1c lithium iron phosphate batteries is 3500 times in the laboratory, some of which reach 5000 times, and the cycle life of 1c ternary lithium ion battery laboratory is 2500. About times. At this point in the cycle life, the actual life of a lithium iron phosphate battery pack is much longer than that of a ternary lithium ion battery. Under the same number of cycles, the remaining capacity of a lithium iron phosphate battery is much greater than that of a ternary lithium ion battery. In addition to the huge gap in cycle life between the two batteries, there are also differences in safety performance. How to treat lithium-ion battery packs as a renewable resource? First of all, lithium-ion batteries contain a large amount of metallic copper and lithium powder, which are scarce resources with high value. In the market, tens of millions of tons of waste lithium-ion batteries are produced every year, and recycling and processing of these waste lithium-ion batteries has high commercial value. Environmental treatment of waste lithium-ion battery packs: coarse crusher, particle crusher, powder classifier, cyclone separator, pulse dust collector, high-pressure blower, industrial automation of the entire recycling process of lithium-ion battery factory, high recycling efficiency, strong processing capacity, and capacity It is a valuable component of 500 kilograms per hour, an annual production capacity of 5,000 tons, and recycling of more than 90% of waste lithium-ion batteries. Defects of lithium-ion batteries The price of lithium-ion batteries with the same voltage and capacity is about twice that of lead-acid batteries (although the price is declining as technology is updated). Because lithium-ion battery components are very active, major accidents such as electrolyte decomposition, combustion, and even explosion may occur if they are used improperly. ●Battery performance deteriorates at low temperatures, the discharge platform decreases, the output power decreases, and the effective power attenuates. Comparison of the safety performance of lithium iron phosphate battery pack and ternary lithium ion battery In terms of the material system, the decomposition temperature of the positive electrode material of the lithium iron phosphate battery pack is about 700 ℃, and the decomposition temperature of the positive electrode material of the ternary lithium ion battery is about 200 ℃. In the laboratory test environment, there was almost no fire in the short-circuited lithium iron phosphate battery cell. Because ternary lithium-ion batteries are different and more prone to fires, ternary lithium-ion batteries have higher requirements for thermal management, and lithium iron phosphate battery packs are more adaptable to temperature and safer. Market analysis of lithium iron phosphate battery pack and ternary lithium ion battery Although the application of lithium iron phosphate and lithium ternary battery does not overlap much, the lithium iron phosphate battery pack is mainly installed in passenger cars, and the lithium iron phosphate battery is important Installed on a family car. But this is because the two applications are different due to factors such as the impact of policies and the current battery energy ratio. However, this market pattern is not absolute. With the development of battery technology and changes in government policies, the future application market for these two types of batteries is still unclear.
