my country's battery industry has the largest output in the world, but the profit per unit output is lower than that of Japan and South Korea. This is important because many core technology intellectual property rights are not in our hands. At the Xiangshan Science Conference, Sun Shigang, an academician of the Chinese Academy of Sciences and a professor at Xiamen University, presented the reality that my country's battery industry is large but not strong. In an interview with reporters, Sun Shigang analyzed that 90% of the lithium-ion batteries used in Apple mobile phones are processed in my country, but my country is in the lower reaches of the value chain, and the money earned is small. The same applies to power and energy storage batteries used in electric vehicles. my country is the world's largest electric vehicle market, and there is a great demand for power and energy storage batteries, but the performance of domestic batteries cannot keep up with the market's development speed. Sun Shigang analyzed that the current high-end batteries on the market mainly come from Japan and South Korea, while domestic batteries are relatively low-end. Sun Shigang told reporters that there are many key technologies involved in batteries. Although my country is a major battery processing country, it often has to purchase foreign patents. For example, lithium iron phosphate electrode materials are widely used in the battery industry, but the patent for this material is in the United States. Moreover, the equipment on the domestic battery processing line is basically imported from Japan or South Korea. How can we use other people's equipment to produce better products than others? Sun Shigang said that these status quo shows that the domestic battery industry lacks original innovation. As far as power and energy storage batteries are concerned, in Sun Shigang's view, the rapid development of the electric vehicle market has put forward higher requirements for battery stability, safety, and environmental protection. This is an important opportunity for technological upgrading of the battery industry. The theme of this Xiangshan Science Conference is the full life cycle management of power and energy storage battery systems. Qin Wenbo, a researcher at the Shanghai Science and Technology Commission, analyzed at the conference that a lot of technological innovation is required to realize the full life cycle management of batteries. Because it requires the sustainable development of resources from battery design, use to recycling. Nissan LEAF electric vehicle is called a model of battery life cycle management. Zhang Jianbo, a professor in the Department of Automotive Engineering of Tsinghua University, analyzed that LEAF electric vehicles have a four-layer design for battery safety protection, so there has not been a single safety accident since it was listed in 2010. Moreover, Nissan has established a special subsidiary to conduct research and development on the echelon utilization of batteries. Sun Shigang told reporters that the current domestic research and development of batteries is mainly concentrated in the field of materials. This is because after the electric vehicle market has become popular, many Ru0026D personnel in the field of materials are attracted to enter the battery field, and the threshold for starting with materials for Ru0026D is relatively low. But to achieve the long-term development of the battery industry, this is far from enough. To develop a better battery system for the future market, it is necessary to carry out more basic research to fundamentally understand the battery system, such as the working mechanism and attenuation mechanism of the battery. Sun Shigang said that if my country's battery industry wants to grow from big to strong, it has to settle down and carry out more original innovations. Technology Zone Why does my country's battery industry have the largest output in the world, but its profits are lower than those of Japan and South Korea? Infineon TRENCHSTOp™IGbT6 reduces the total loss of the compact motor controller by more than 20%. How much do you know about the battery concept in the future? Solar panel Mpp pulse load power supply processing method South Korea Customs will be included in the blockchain system, blockchain is popular with concept stocks rise
