What are the differences between lithium iron phosphate batteries and ternary batteries? [Outer packaging] Lithium batteries can be divided into square batteries, soft-pack batteries and cylindrical batteries. [Material system] At present, the mainstream lithium iron phosphate batteries and ternary material batteries refer to lithium batteries that use lithium iron phosphate and ternary materials as the positive electrode materials. Ternary materials refer to cathode materials with Ni, Co, Mn or Ni, Co, and Al as the core elements. [Comprehensive evaluation] The energy density of lithium iron phosphate battery cells is 120Wh/kg, and 80Wh/kg after grouping; the energy density of ternary lithium battery cells is 180Wh/kg, and the energy density after grouping is 110Wh/kg. From the data point of view, in terms of energy density, ternary lithium batteries are superior to lithium iron phosphate batteries; in terms of cycle life, the two are equivalent. The cycle life of single cells is greater than 3000 times. After the batteries are grouped, due to the use of labor The situation becomes worse and more complicated, and the life span will be reduced to a certain extent. The life span of the battery pack is equivalent to 6 years and 150,000 kilometers. The battery used in EV200 is a ternary lithium battery. At present, the energy density of lithium iron phosphate batteries has basically reached the theoretical limit, while the energy density of ternary batteries has much room for improvement. In terms of comprehensive capacity density, power density, cycle life, and low-temperature performance, the comprehensive performance of the ternary battery is better than that of the lithium iron phosphate battery.
