Briefly describe the difference between lithium iron phosphate batteries and ternary lithium batteries

Advantages of lithium iron phosphate power lithium-ion battery The first advantage is long service life. Lithium iron phosphate power lithium-ion battery, the cycle life can reach more than 2000 times. Under the same conditions, the service life of the ternary lithium battery is 1 to 1.5 years. The same brand new lithium iron phosphate battery used under the same conditions has a service life of 7 to 8 years. The second advantage is fast charging. Use a special charger for lithium batteries and charge the battery at 1.5C for 40 minutes in accordance with the standard requirements. The third advantage of Pared lithium iron phosphate battery is high temperature resistance and good high temperature performance. Lithium batteries can withstand the highest temperature up to 350 ℃-500 ℃, while lithium manganese oxide and lithium cobalt oxide batteries are only around 200 ℃. The advantage of ternary lithium battery is low temperature resistant and high energy density. The ternary lithium battery can be used normally at minus 20 degrees, because the battery itself will generate heat during the discharge process. In terms of high-rate charging and low-temperature resistance, ternary lithium batteries have great advantages. Energy density is the energy that a unit weight of the battery can hold. The capacity of the ternary lithium battery has reached 200Wh/kg, which is nearly double the capacity of lithium iron phosphate. However, the safety of ternary lithium batteries is relatively poor. Analysis will occur at 250-300°C. It will stop after encountering the combustible electrolyte and carbon materials in the battery. The heat that appears will further aggravate the positive electrode analysis, and it will deflagrate in a very short time, which is very dangerous. Therefore, compared with ternary lithium batteries, lithium iron phosphate batteries with low raw material prices, high safety, and long service life have obvious advantages.
