Introduce the advantages and disadvantages of several new energy vehicle batteries

1. The raw materials are easily available, the price is relatively low 2. The high-rate discharge performance is good 3. The temperature performance is good, and it can work in the environment of -40~+60℃ 4. It is suitable for floating charging and has a long service life. Disadvantages: 1. The specific energy is low, generally 30~40Wh/kg2, the service life is not as good as the nickel-cadmium battery 3. The manufacturing process is easy to pollute the environment, so it must be equipped with three waste treatment equipment. 2. Advantages of nickel-hydrogen batteries: 1. Compared with lead-acid batteries, the energy density is greatly improved, the specific energy is 65Wh/kg, and the volumetric energy density is increased by 200Wh/L; 2. The power density is high, and it can be charged and discharged with high current. 3. Good low-temperature discharge characteristics. 4. Cycle life (increased to 1000 times). 5. Environmental protection and pollution-free. 6. The technology is more mature than lithium-ion batteries. Disadvantages: 1. Normal working temperature range -15~40℃, poor high temperature performance 2. Low working voltage, working voltage range 1.0~1.4V3, the price is more expensive than lead-acid batteries, nickel-hydrogen batteries, but the performance is worse than lithium-ion batteries . 3. Advantages of lithium ion battery: 1. The specific energy is as high as 160Wh/kg 2. The self-discharge rate is low, no memory benefit, 3. No pollution, long life, light weight, voltage up to 4.7V Disadvantages: Lithium will burn when exposed to water. Overcharging is very dangerous, so higher battery management module technology is required. 4. Advantages of fuel power battery: 1. High specific energy and long vehicle mileage; 2. High power density and high current charge and discharge; 3. Environmental protection and no pollution. Disadvantages: 1. Complex system and poor technological maturity; 2. The construction of hydrogen supply system is lagging behind; 3. There are high requirements for sulfur dioxide in the air. Due to serious domestic air pollution, fuel-powered battery vehicles in the country have a short lifespan.
