Which is better, lithium iron phosphate battery or ternary lithium battery?
I think ternary lithium battery is better. Ternary lithium battery has longer life, higher energy density and lighter weight. In the future development of new energy vehicles, ternary lithium batteries can solve safety and cost problems and can be used as new energy storage devices for future vehicles.
The advantages of lithium iron phosphate batteries are:
Higher safety, longer life, low raw material cost, support for fast charging, a wide operating temperature range and stability that is the best. the best of current vehicles Use the best lithium batteries;
Disadvantages: There is still a large gap in densityenergy efficient compared to ternary lithium batteries. When the temperature is below -10°C, the charging efficiency decreases. When the temperature is too low, the battery capacity will be affected. Models using lithium iron phosphate batteries are not suitable for driving in the north, especially in extremely cold areas like northeast China.
The advantages of ternary lithium batteries are: high energy density, good cycle performance, more suitable for the future development trend of new energy vehicle batteries, suitable for northern weather conditions and more stable at low temperatures;

Disadvantages: The high temperature structure of Ni-Co-Al is unstable, resulting in poor safety and danger at high temperatures. However, this problem can be solved through various systems, but the current cost is relatively high.
