Analysis on the current status of power lithium-ion battery manufacturing technology in the United States, Japan, South Korea and my country

The current status of power lithium-ion battery manufacturing technology in the United States, Japan, South Korea and my country [Abstract] A technological innovation often brings about the emergence and development of an industry. The advancement of lithium battery technology at the beginning of the 20th century made the new energy industry appear in people's vision. Reduce non-renewable resources such as petroleum. For decades, the research on petroleum as an alternative power battery has never stopped. This article has studied the current status of power lithium-ion batteries from the perspective of technological innovation for many years, the existing problems, and the Gini coefficient of knowledge and Some countermeasures are proposed for these problems of product substitution elasticity. At present, technological innovations in lithium batteries abroad include two important aspects: one is to further improve the energy density of lithium batteries; the other is to improve the safety performance of lithium batteries. At the same time, these two aspects are also the focus of the development of the lithium battery industry. 1. In the current environment of increasingly fierce competition in the battery industry in the Japanese battery industry, technological innovation determines its market share. In order to maintain its dominant position, Japanese academia and industry have always maintained a high degree of enthusiasm and huge investment in battery research and development, and have achieved certain results and a series of research results. Japan has developed a new material for rechargeable lithium batteries used in smart phones and electric vehicles. This material not only reduces the size of the battery, but more importantly, increases the power of the battery by 10 times. Japanese researchers have developed an electrolyte that appears as the current solid-state medium, and created a solid-state lithium battery. The solid-state lithium battery has the characteristics of high conductivity and can be used for power supply in a wider temperature range, physical damage and high temperature resistance, processing The process is simple and cheap, and it may become an important driving force for the promotion and application of electric vehicles. 2. The development status of the U.S. battery industry. Electric vehicle processing companies in the U.S., including the U.S. scientific community, have also increased the research and development of lithium batteries. On February 11, 2014, Joseph and Simon, a chemist at the University of North Carolina, U.S. Joseph De Simeone) has discovered a new special material that can replace perfluoropolyether (PFPE), the only combustible component in lithium batteries, and found that it can prevent spontaneous combustion and explosion of lithium batteries under high temperature conditions. One discovery cleared the technical barriers for the development of a new generation of lithium batteries with higher safety performance, and promoted the technological advancement of lithium batteries and electric vehicles in the United States. 3. South Korean battery industry South Korea is the world’s leading battery manufacturer camp and one of the world’s leading processors. The development of batteries, rechargeable hybrid vehicles and electric vehicles, portable electronic products and medical technology is driving the development of the battery industry, South Korea , South Korea is also increasing its investment in battery technology, in order to extend the service life of the battery, improve safety, and reduce processing costs. South Korea’s battery manufacturing technology and Japan share the world’s excellent level, but due to the Japanese market’s monopoly of the company’s core materials, the processing power and market share are still lower than Japan and South Korea. Major groups such as Samsung, LG, Hanwha, POSCO, Lotte, and GS have invested heavily in materials. For example, it is believed that in the near future, South Korea’s core materials will catch up or go hand-in-hand with Japanese companies. 4. The technological innovation history of my country's power lithium-ion battery industry. Power batteries have always been regarded as one of the most promising power technologies. Countries around the world have invested a lot of resources in the development of practical batteries. In the 863 plan in 1987, the research and development of lithium batteries was listed as a key project, and during the ninth five-year plan period, lithium batteries were listed as a national key scientific and technological public relations project, which is considered to be an important economy for the new electronics industry. Rising points, thereby promoting the technological progress and economic development of the entire industry.
