The differences between ternary lithium and lithium iron phosphate batteries are as follows:
1. The positive electrode material is different. The positive electrode material of ternary lithium battery is lithium nickel-cobalt manganate or lithium nickel-cobalt aluminate, while the positive electrode material of lithium iron phosphate battery is lithium iron phosphate;
2. Different performance at low temperature;
3. The battery life is different, the battery life is better;
4. Different melting point, lithium iron phosphate battery melting point is higher.
Ternary lithium battery and iron phosphate lithium battery itself are two materials, although the function of the battery is the same, but after all, the material is not the same, so there are some differences.
The positive electrode materials of ternary lithium and lithium iron phosphate batteries are different, so the physical properties are different. For example, the capacity of lithium iron phosphate battery will decay to 50% at the low temperature of -20 degrees, while the capacity of ternary lithium battery can be higher than that of lithium iron phosphate battery at -30 degrees.
In addition, for the same size or weight, a ternary lithium battery has to store more power than a lithium iron phosphate battery, meaning it has more capacity and thus more battery life. This is because the chemical properties of the cathode materials are different. At the same mass, the capacity density of ternary lithium battery is 1.7 times that of lithium iron phosphate battery.
In a word, with the continuous progress of science and technology, the performance of ternary lithium and lithium iron phosphate batteries will be improved, so as to meet the needs of consumers.
