What urgent problems do electric vehicles currently face that need to be solved?

　　Encouraged by national policies, many consumers have purchased pure electric vehicles, and more and more automakers are manufacturing pure electric vehicles. Many people say that pure electric vehicles are the trend of the future, and the country has also issued some plans to ban the sale of fuel vehicles. However, are pure electric vehicles really the future? The answer is of course no.

　　Indeed, new energy vehicles are the future, but this new energy is not necessarily electricity, it may also be other energy sources. And there are many kinds of batteries used in pure electric vehicles, such as lithium batteries, hydrogen fuel cells, etc. Pure electric vehicles are currently facing many problems that need to be solved, such as slow charging speed, battery degradation, driving range, high battery replacement cost, etc.

　　The development of battery technology has encountered bottlenecks, which will be difficult to break through in the future. Let's take an example from everyone. Everyone has a smartphone in their hands. The performance of the smartphone battery will decrease as the number of charge and discharge times increases. When the phone is first bought, it can be on standby for a day and a half, but after a year of use, it needs to be charged three times a day. This is a problem that troubles many mobile phone users.

　　Similarly, the battery of a pure electric vehicle also decays, and when the battery of a pure electric vehicle decays, it affects the driving range. The cost of replacing the battery of a general pure electric vehicle is very high, which is why many consumers are reluctant to buy pure electric vehicles. Moreover, if the replaced waste batteries are not properly recycled, they will also cause serious pollution to the earth's environment.
