How Many Years Does the Battery of a Pure Electric Vehicle Last?

[DamianFitz]

Currently, the batteries used in electric vehicles are: ternary lithium batteries, lithium iron phosphate batteries, and nickel-metal hydride batteries. Among them, nickel-metal hydride batteries are the most stable, lithium iron phosphate is the safest, and ternary lithium batteries have the highest capacity. Below is a detailed introduction: Ternary Lithium Battery: Good at cooperation, with the highest capacity for the same weight. However, the components are tightly packed together, leading to slightly higher temperatures. Therefore, ternary lithium batteries have strict heat dissipation requirements, and for safety, each battery cell must have a protective device. Lithium Iron Phosphate Battery: Favored by most automakers. Although the capacity per unit weight is not as high as that of ternary lithium batteries, it has good thermal stability, is less prone to overheating, and the cost of heat dissipation components is much lower. In addition, it has advantages such as high energy density, small size, long battery life, and good safety.
