Lithium Iron Phosphate Battery

At present, there are two main types of automotive power batteries: lithium iron phosphate and lithium ternary batteries.
The so-called lithium iron phosphate battery refers to lithium iron phosphate as the cathode material of lithium-ion batteries.
This type of battery is characterized by the absence of precious metal elements In practice, lithium iron phosphate batteries have high-temperature resistance. It will not decompose until the temperature exceeds 600 degrees Celsius It is more stable than ternary lithium batteries.
In addition, lithium iron phosphate batteries also have an advantage in terms of battery life Currently, some entry-level electric vehicles are equipped with LiFePO4 batteries.
Mainly because of its low cost, high safety, durability, and other characteristics.
However, the positive electrode of LiFePO4 has a low solid density and poor electrical conductivity, slow diffusion of lithium ions, and slow charging and discharging at high rates.
Therefore, high-end electric vehicles usually use the more efficient lithium ternary batteries as their power cells.
