How many years can an electric vehicle battery generally last?

[VanJune]

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: Excels in cooperation, offering the highest capacity for the same weight. However, its components are tightly packed together, leading to higher temperatures. Therefore, ternary lithium batteries have stringent cooling requirements, and for safety, each battery cell must have a protective device. Lithium Iron Phosphate Battery: Favored by most automakers. Although its capacity per unit weight is not as high as that of ternary lithium batteries, it has excellent thermal stability, is less prone to overheating, and significantly reduces the cost of cooling components. Additionally, it boasts advantages such as high energy density, compact size, long battery life, and good safety.
