At present, we have formed a complete lithium battery system, and have mastered the structural characteristics, manufacturing technology and production technology of power batteries, but the uniformity, stability, consistency and safety of single battery products are still relatively large compared with foreign countries Bian Shuguang, Deputy Director of the Ministry of Science and Technology of the People's Republic of China, introduced the development progress and key deployment of China's new energy vehicle power batteries.
The main markets for lithium-ion batteries are the United States, Europe and Asia, with China, Japan and South Korea now the main producers, Bian said. From the perspective of enterprises, the United States has a strong R & D design capacity, Japan's production standards are more strict, and China's market share in the world ahead of Japan, occupying the first place. The gap between China and foreign countries is mainly in the area of single cell batteries, but there is still a big gap in materials, even in some basic research on basic power sources, including consistency, battery safety, and core technology This is also the first step of our enterprise innovation. So far, China's lithium battery power supply should reach 1.67 billion watt hours, while we basically occupy the international market share of nearly 50% of the market, in the market share continues to progress.
In Bian Shuguang's view, we still have relatively big problems in the area of lithium battery materials, mainly manifested in: First, high-end battery materials can not be self-sufficient at present, low-end materials are surplus, high-end materials are insufficient, the research on the production technology of the material is still deficient, and the stability of the material is still insufficient. Second, there are still some problems in the battery design, multiple batteries can not meet the demand. Third, the battery recycling planning is insufficient, the production equipment level is not high and so on the question still exists. There is still a gap between the manufacturing accuracy of single cell and the temperature characteristic of single cell and the foreign enterprises in temperature adaptation. In addition, the Battery Manufacturing Process Imitation phenomenon, the lack of their own innovation capacity, China's enterprises should focus on learning from the West's mature experience and equipment level. At the same time, the battery in our country lacks some detection functions, and is still insufficient in the aspects of data collection reliability, SOE accurate estimation, heat management and safety management In connection with heat dissipation, protection, use, maintenance, charging and other aspects need to be further refined.
In China, Bian predicts that by 2020 it will be the first stage of the technology, mainly the development of new lithium ion batteries, an increase in energy density, and an intelligent manufacturing of power cells. By 2025, china should make remarkable progress in new motor technology, connect the development of power battery industry with international advanced level, and cultivate large-scale companies with strong international competitiveness. By 2030, the power battery industry has entered a new stage of development, with the improvement of the energy of the cell and the application of new materials to reach the international leading level.
