What Type of Battery Do Electric Vehicles Use?

[DiSkylar]

Currently, the batteries used in electric vehicles are: ternary lithium batteries, lithium iron phosphate batteries, and nickel-metal hydride batteries. Among these, nickel-metal hydride batteries are the most stable, lithium iron phosphate batteries are the safest, and ternary lithium batteries have the highest capacity. Below is a detailed introduction: Ternary Lithium Battery: Excels in collaboration, offering the highest capacity for the same weight. However, its tightly packed components generate higher temperatures, so ternary lithium batteries have stringent cooling requirements. To ensure safety, each battery cell must be equipped with a safety device. Lithium Iron Phosphate Battery: Favored by most automakers. Although its capacity per unit weight is lower than 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 offers advantages such as high energy density, compact size, long battery life, and superior safety.
