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

The difference between lithium iron phosphate battery and ternary lithium battery: ①The energy density is compared with lithium iron phosphate battery monomer, the energy density is 120Wh/kg, the lithium iron phosphate battery pack is 80Wh/kg; the ternary lithium battery monomer, the energy density is 180Wh/kg, the energy density after grouping is 110Wh/kg. From the data point of view, in terms of energy density, ternary lithium batteries are better than lithium iron phosphate batteries. ②Safety comparison The liquid electrolyte of ternary lithium battery is flammable and explosive, and it is easy to trigger thermal runaway during long-term use. The growth of lithium dendrites during charging and discharging can easily pierce the diaphragm, causing short circuit of the battery and causing safety hazards. The lithium iron phosphate battery pack has the advantages of high temperature resistance, strong safety and stability, and better cycle performance in actual use. ③In terms of cost, since lithium iron phosphate batteries do not contain precious metal materials, the cost of raw materials can be compressed very low. The ternary lithium battery uses lithium nickel cobalt manganate as the positive electrode material and graphite as the negative electrode material, so the cost will be much more expensive than the lithium iron phosphate battery.
