What are the technical difficulties of powered lithium batteries?

The rise of new energy has changed the quality of many industries. Before the batteries of ordinary electric bicycles in our lives, lead-acid batteries were always the choice of electric vehicles, but everyone knows that lead-acid batteries are more polluted. The modern pursuit of green environmental protection concepts and the gradual popularization of the concept of lithium batteries, because the performance of lithium batteries is better than the trend of environmentally friendly energy cycles and lead-acid batteries, making the power of lithium batteries more and more extensive, in the automotive field. However, three factors, such as range, charging speed, and safety performance, have become the three major technical difficulties of power lithium batteries.

A,  Close range: As technology matures, lithium-ion batteries as a power source for electric vehicles range from less than 100 km to about 300 km in the beginning, and the range of individual mainstream models has exceeded 400 km. However, compared with the current fuel vehicle, the main mileage is 500 kilometers, and there is a certain gap. This problem may be solved with a series of monolithic batteries, but the negative problem is that it is too large to increase the size of the car.

Second, slow charging: Lithium batteries that are short relative to the range of the drive, but are slower in power, are the development of electric cars. At normal speeds, lithium-ion batteries in electric cars take four to eight hours. Now that there is a fast-charging lithium battery, it can be full in 1 to 2 hours, but its negative impact is very large, the life span will be reduced to 1/3, and the battery performance will be greatly reduced. Refueling time does not exceed five minutes, and security and stability can be guaranteed.

The third is to improve safety performance: Since the birth of lithium ions, safety problems have always plagued consumers.

I believe that although there are difficulties, the development of power lithium batteries will be better and better, because the power lithium batteries have good cycle performance and long-lived green energy will become the mainstream of the automotive battery industry.
