What are the disadvantages of lithium battery electric vehicles?

At present, the price of lithium battery electric bicycles is generally several hundred to one thousand yuan higher than that of lead-acid battery electric bicycles, so it is difficult to get consumer recognition on the market. Lithium batteries are light and environmentally friendly, and there will be no environmental pollution after they are discarded. Once the application technology is mature and the market sales increase, the price of lithium battery electric bicycles will come down. ●Excessive charging time is counterproductive. In some electric vehicles, after charging for a certain period of time, if the charger is not removed, the system will not only stop charging at this time, but also start a discharge-charge cycle. Perhaps the manufacturer of this approach has its own purpose, but it is clearly detrimental to the life of the battery. Therefore, after purchasing a lithium battery electric vehicle, you should consult the company or dealer to do a good job of maintaining the lithium battery. ●Lithium battery power needs to be improved. Compared with lead-acid batteries, lithium batteries are much less resistant to fluctuations in charging and discharging. This is a major symptom that lithium batteries cannot be used effectively for current high-power vehicles, which leads to reduced durability. . ●Safety issues highlight the safety of lithium batteries still needs to be improved. The hidden dangers of fire, combustion and even explosion of lithium batteries cannot be completely eliminated at present. A collision of a vehicle may cause the positive and negative electrode materials of the battery to break through the diaphragm, and the energy quickly recharges to the ultra-high current when the battery is instantaneous when braking. This will cause the battery to short-circuit, increase the temperature, and cause combustion or even explosion.
