What are the types of lithium batteries for new energy vehicles?

Classification of new energy vehicle power lithium battery 1. Lithium battery: It is one of the most commonly used battery types in electric vehicles. Although it has not been a long time since its birth in 1970, it has high energy density and long cycle life. Features quickly occupy most of the electric vehicle battery market. The lithium batteries currently on sale for electric vehicles are mainly lithium iron phosphate batteries and ternary lithium batteries. 2. Ni-MH power lithium battery: It is the only battery system that has been actually verified and commercialized and scaled in the battery system used in hybrid electric vehicles. The current 99% of the market share of the current hybrid lithium battery is nickel-hydrogen power lithium battery. The representative of commercialization is Toyota's Prius. 3. Fuel-powered lithium-ion battery: a device that directly converts the chemical energy of fuel and oxidant into electrical energy through electrode reaction. Fuel-powered lithium-ion batteries do not need to be charged. They have the advantages of high specific energy, long service life, low maintenance workload, and continuous high-power power supply. In addition, fuel-powered lithium-ion battery vehicles can reach the same driving range as fuel vehicles. 4. Lead-acid battery: As a relatively mature technology, it is the only battery for electric vehicles that can be processed in large quantities because of its low cost and ability to discharge at a high rate. However, the specific energy, specific power, and energy density of lead-acid batteries are very low, and an electric vehicle using this as a power source cannot have a good speed and cruising range. 5. Graphene batteries: Graphene batteries are the most reliable and discussed power lithium batteries for future new energy vehicles. There are two ways to use this material in combination with lithium batteries: one is to use graphene composite materials as the conductive agent of the lithium battery; the other is to directly use it as the negative electrode, the effect is to increase the activity of the lithium battery pack, thereby improving electric vehicles The cruising range and charging speed.
