Advantages and disadvantages of ternary lithium iron batteries and lithium iron phosphate batteries

No ternary iron lithium battery, it is ternary lithium battery.

Advantages:

Lithium ternary batteries: high ratio of electrical energy, high voltage, good power characteristics, but safety is worse. Temperature range is better;

Lithium iron phosphate batteries: electric energy ratio is low, voltage is average, stable performance, good safety. Temperature range is better. High cycle life of lithium iron phosphate batteries are generally more than 1000 cycles, high up to 2000 cycles, electric buses are used in lithium iron phosphate battery pack.

Disadvantages:

Lithium ternary battery: high capacity, good consistency, low cycle life, relatively large size, low temperature performance is not good.

Lithium iron phosphate battery: small size, can be loaded with more capacity, winter performance does not decline much, the initial capacity is larger than lithium iron has a significant mileage advantage, the life of the later part of the life will have a more significant decline.

Expanded information:

Lithium iron phosphate batteries on the left side of the olivine structure of LiFePO4 material constituting the positive electrode, which is connected to the battery's positive electrode by an aluminum foil. On the right is the negative electrode of the battery made of carbon (graphite), which is connected to the negative electrode of the battery by a copper foil. In the center is a polymer diaphragm that separates the positive electrode from the negative electrode, allowing lithium ions to pass through the diaphragm while electrons cannot. The inside of the battery is filled with electrolyte, and the battery is hermetically sealed by a metal casing.
