Classification of new energy vehicle batteries

With the continuous popularization of new energy vehicles, batteries as energy storage units of vehicles have attracted more and more attention.

New energy vehicle batteries can be roughly divided into two categories, one is lithium iron phosphate battery (LFP), and the other is lithium cobalt oxide battery (NCA, NCM).

1. Lithium iron phosphate battery (LFP): The negative electrode material of this battery is lithium ferrous phosphate, which has high safety, is not easy to explode and does not pollute the environment. However, its capacity and weight are relatively low and its service life is short, so it is only suitable for urban commuting, short-distance travel and other scenes.

2. Lithium cobaltate battery (NCM NCA): The cathode material of this battery is usually made of lithium cobaltate or cobalt oxide, with high capacity-weight ratio and long service life. However, compared with other batteries, lithium cobaltate batteries have higher costs and greater safety risks. The ternary lithium battery supports high-power charging and is suitable for long-distance driving and high-speed driving.

3. Lithium iron phosphate battery (LFP)- lithium cobalt oxide battery (NCM) hybrid battery: This combined battery is suitable for electric vehicles and hybrid vehicles, and has reached a balance in safety and cost performance.

No matter what kind of battery it is, it is very important to choose the model and use that suits you.
