Insufficient battery life may be fully resolved in 2020

According to the statistics of China Association of Automobile Manufacturers, in 2013, China's new energy vehicles produced 17,533 vehicles, an increase of 39.7% over the same period of last year. Compared with the scale of ordinary automobiles that we sold over 20 million vehicles in the same period, it is rare and less difficult to promote new energy vehicles. One is the battery problem. Then, why is the problem of new energy vehicle battery not resolved well?

Insufficient endurance

The battery determines how far the new energy car can run. In recent years, the new energy automobile industry has been greatly developed along with the frequent introduction of various policies. However, due to the limitation of batteries, the development bottleneck has not been solved. Consumers are generally worried that the car's endurance capacity is insufficient, the willingness to purchase is not high, and the company's willingness to produce also declines. New energy vehicles have also fallen into a vicious circle of market promotion.

A survey of professional organizations in several cities found that most consumers drive less than 50 kilometers a day. The current range of new energy vehicles on the market can meet the daily needs of most consumers. The person in charge of a well-known car company in China also publicly stated that according to the daily use situation, there is no need to worry too much about the endurance problem.

On the other hand, there are also professional institutions that show that only when the battery life is more than 300 kilometers, can new energy vehicles be truly commercialized. Therefore, the batteries commonly used in the market are still far from the requirements for commercialization.

In China, the research of battery raw materials has gone through 10 years of exploration, and the power battery technology has been greatly improved in terms of reliability and safety. In particular, the lead-carbon “super battery” developed by Jiangsu Tianneng Group has been successfully tested. The development of large-capacity and high-efficiency safety batteries by Tianjin University is a representative result. But I have to admit that these explorations still make it difficult to change the status quo of the entire industry.

“At present, domestic enterprises still have a big gap in the large-scale commercial use of new energy vehicles in terms of electronic control, battery and motor.” Zhao Bo, deputy director of the Electronic Information Department of the Ministry of Industry and Information Technology, believes that especially the existing ones. The reliability and stability of battery technology, the energy density of products are not high, and the cycle life is not long, which affects the development of new energy vehicles.

Jingzhong Wang, secretary-general of China Battery Industry Association, also said that at the current level, the exploration of new materials and the optimization of management systems should be carried out in parallel, but the focus should be on the exploration of new materials. "At present, China's technology research and development has a good momentum, and the results of commercial value are constantly emerging. The research level is basically the same as the international advanced level. According to this research and development speed, the possibility of solving the battery problem before 2020 is very high." Jingzhong Wang said optimistically.
