Source: 2020 - 04 - 06 21:57 hits: time the United States, Japan, South Korea and China power battery manufacturing technology status quo of the Abstract 】 A technological innovation often leads to the emergence and development of an industry. Lithium-ion batteries in the early 20th century technological advances allow new energy industry appear in people's field of vision. Reduce the non-renewable resources such as oil, for decades, oil can be used as an alternative power battery research has never stopped, from the Angle of technology innovation, this paper studies the status quo of power battery for many years, the existing problems, combining with the knowledge of the gini coefficient and the product of the elasticity of substitution of these problems puts forward some countermeasures. At present, foreign in the field of lithium ion battery technology innovation mainly includes two aspects: one is to further improve the energy density of lithium ion batteries; Second, improve the safety performance of lithium-ion batteries. At the same time, these two aspects is also the key point of the development of the lithium ion battery industry. 1. Japan battery industry in the current battery industry increasingly competitive environment, technological innovation determines the market share. In order to maintain their dominant position, academia and industry of Japan has maintained a high degree of enthusiasm and the battery research and development of huge investment, and obtained a certain result of a series of research results. Japan has developed a kind of used for smart phones and rechargeable lithium ion batteries of electric cars new material, the material not only reduced the size of the battery, and, more importantly, will also be battery power increased 10 times. Japanese researchers have developed a kind of electrolyte to produce the solid medium, and create a solid state lithium ion batteries, solid-state lithium battery has the characteristics of high conductivity, can carry on the power supply under a wider temperature range, physical injury and high-temperature resistance is strong, the production process is simple and cheap, it can be popularized and applied electric cars one of the main driving force. 2. The battery industry current situation of the development of electric vehicle production enterprises in the United States, including the American scientific community also increased the lithium ion battery research and development, on February 11, 2014, the United States, a chemist at the university of north Carolina, Joseph, Simon, Joseph desimone) Newly discovered a kind of special material, can replace the only combustibles in lithium battery perfluorinated polyether ( PFPE) , found that can make the lithium battery under the condition of high temperature won't appear the phenomenon of spontaneous combustion and explosion, the findings for the development of a new generation of the safety performance of lithium-ion batteries more cleared the technical barriers, the promotion of technology progress in lithium batteries and electric cars in the United States. 3. South Korea battery industry is one of the world's advanced battery maker camp as well as one of the world's leading manufacturers, batteries, plug-in hybrids and electric vehicles, portable electronic products and the development of medical technology is driving the development of battery industry, South Korea, South Korea is also increasing its investment in battery technology, in order to prolong the service life of battery, improve security, reduce the production cost. South Korea and Japan's share of the world's leading battery manufacturing technology level, but due to the Japanese market monopoly, the core material, make the productivity and market share is still less than Japan, South Korea, in order to improve the production of rechargeable battery material behind Japan, South Korea enterprise investment boom lift the battery materials, including samsung, L G, hanwha, posco, lotte, GS group to invest heavily in main material, such as believe in the near future, the core of the south Korean materials will catch up with or go forward hand in hand with the Japanese enterprises. 4. China's technology innovation process of the power battery power battery industry has always been considered one of the most promising power technology. All countries in the world has poured resources development practical battery. In 1987, '863' plan of lithium ion battery research and development as a key project, and during the 'ninth five-year plan, the lithium ion battery technology public relations is listed as national key project, it is regarded as a new major economic growth point of the electronics industry, in order to impel the technology progress and economic development of the industry.
