Lithium battery problems and solutions in China

Source: 2020 - 04 - 10 hits lie: lithium-ion batteries in China problems and solutions at present, our country the lithium ion battery energy density and power density has increased significantly, but in terms of key materials and manufacturing technology represented by Japan and the United States and the international advanced level there is still a large gap. Research on key technology problems in the field, will provide the key for the development of China's energy of materials, technology and knowledge, be in a better position to make China in the international competition, for China's energy security, environmental protection and the improvement of people's living standard has inestimable significance. Based on the research of advanced energy storage materials, development of high energy and high power density, safe and reliable, long life, environmental protection energy storage equipment and complex system, promote its practical application, it is of great significance of the development of the new type of power battery, the reasonable distribution of the renewable energy, and provide a new method of effective power regulation in electric vehicles, hybrid electric vehicle in China, large and medium-sized electric tools, electronic communications, aerospace, national defense and other fields of great demand, for its large scale, high efficiency, reasonable application opens a new route. The industrial upgrading in China and the establishment of rational resource allocation system has important practical significance. In addition, the domestic aerospace large-capacity lithium ion battery research and development is still in its infancy, the cycle life, multiplier charge-discharge performance and security remains to be further improved. At the same time, in order to meet the actual demand of space application, the influence factors of space environment on the design optimization of the power supply system must be considered to use and the uniformity of single battery performance, make the power work reliably in the complex space environment.
