Classification of new energy vehicle batteries
With the continued popularity of new energy vehicles, batteries as energy storage units of vehicles are attracting more and more attention.
New energy vehicle batteries can be roughly divided into two categories, one is lithium iron phosphate (LFP) battery and the other is lithium cobalt oxide (NCA, NCM).
1. Lithium iron phosphate (LFP) battery: The positive electrode material of this battery is made of lithium iron phosphate, which is highly safe and not prone to explosion and environmental pollution. However, its capacity and weight are relatively small and its service life is short. It is only suitable for urban travel, short-distance travel and other scenarios.
2. Lithium cobalt oxide battery (NCA, NCM): the cathode material of thistype of battery is usually made of materials such as lithium cobalt oxide or cobalt oxide, which has a high capacity/weight. ratio and long life. However, lithium cobalt oxide batteries have higher costs and greater safety risks than other batteries. The ternary lithium battery supports high-power charging, so it is suitable for long-distance driving and high-speed driving scenarios.
3. Lithium iron phosphate (LFP)-lithium cobalt oxide (NCM) battery hybrid battery: This combination battery is suitable for electric vehicles and hybrid vehicles, achieving a balance between safety and cost-effectiveness.
Whatever the type of battery, it is very important to choose the model and use that suits you.
