What are the fundamental advantages and disadvantages of lithium-ion battery electric vehicles?

Advantages of lithium-ion battery electric vehicles: lithium-ion batteries have long life, light weight, and small size. Currently, lithium-ion battery electric vehicles have diversified brands, such as Yadi, Giant, Emma and other lithium-ion electric vehicles. Charging for 6 to 8 hours, it can run 30 to 145 kilometers according to the difference in battery capacity, and the weight is only about 1/5 of that of lead-acid batteries. The biggest advantage of lithium-ion battery electric bicycles is long life. The most expensive thing about lithium-ion batteries is to see their appearance. In fact, the cost is about the same as lead-acid batteries. At present, lithium-ion batteries are guaranteed for 2 years, while lead-acid batteries are guaranteed for 1 year. Therefore, self-made goods are naturally compromised. Lithium-ion batteries are basically no problem for 3-5 years. Lithium-ion batteries have activation-free characteristics. After a period of time, the battery will enter a sleep state, and the capacity will be lower than normal. But lithium-ion batteries are easy to activate, as long as 3-5 normal charge and discharge cycles can activate the battery and restore the normal capacity. Due to the characteristics of the lithium-ion battery, it was chosen to have almost no image effect. Therefore, the user should not go beyond the essentials and equipment during the activation process of the new lithium-ion battery. So you don't have to worry about it being put down. There is no pressure or pressure after storage for 3 years. Lithium-ion batteries have no image effect. Consumers have always been worried about the image effect of the battery when charging lead-acid batteries and nickel batteries. When lithium-ion batteries are used, everyone can take a good word, and lithium-ion batteries have no effect.象 effect. The peak of battery capacity will not suddenly change. The shortcomings of lithium-ion battery electric vehicles are also: the long charging time of lithium-ion batteries is counterproductive. It mainly eats and does not support the safety of lithium-ion batteries. The safety of lithium-ion batteries still needs to be improved. The hidden dangers of fire, combustion and even explosion of lithium-ion batteries cannot be completely eliminated at present. The collision of the vehicle may cause the positive and negative materials of the battery to break through the barrier, and the energy quickly recharges to the instantaneous ultra-high current when the battery is braked. The city causes the battery to short-circuit, increase the temperature, and cause burning or even explosion. The short-circuit causes the precipitation of lithium ions, which can cause fire and combustion in contact with the atmosphere. The electrolyte of a lithium ion battery is an organic electrolyte, and these substances may burn after being in contact with the atmosphere.
