Comparative analysis of ternary lithium battery and lithium iron phosphate battery

The material used in ternary lithium batteries, nickel, cobalt, and aluminum, will be unstable in high temperature and there is a danger of explosion, so high temperature safety is poor, but ternary lithium batteries have good low temperature performance; lithium iron phosphate batteries have good high temperature performance, It can still be normal at 60°C. The disadvantage is that the low temperature below -10°C will be greatly discounted, or even unusable, just the opposite of the ternary lithium battery. 2. Volume and weight Although lithium iron phosphate is small and light, it is inferior to ternary lithium batteries. Under the same size conditions, lithium iron phosphate can be loaded with 10AH, and ternary lithium batteries can usually be loaded with more than 15AH. 3. Energy density lithium iron phosphate battery, the single energy density is 120Wh/kg, after the group is 80Wh/kg; the ternary lithium battery monomer, the energy density is 180Wh/kg, the energy density after the group is 110Wh/kg. From the data point of view, the ternary lithium battery is superior to lithium iron phosphate in terms of energy density. 4. Safety The liquid electrolyte of ternary lithium battery is flammable and explosive, and it is easy to trigger thermal runaway during long-term use, causing safety hazards; lithium iron phosphate battery is resistant to high temperature, very stable, and has high safety. 5. Cost 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; lithium iron phosphate batteries do not contain precious metal materials, so compare ternary lithium batteries , The price of lithium iron phosphate is already cheap. 6. Although the battery cell density of the ternary lithium battery is very high, it must be combined with a set of complex battery protection equipment due to its poor safety and high temperature resistance. These equipment have increased the weight, making the ternary battery in The advantage of energy density is weakened; Statement: Some pictures and content of articles published on this site are from the Internet.
