The research and development of CR1620 battery separators needs to consider the market and be targeted

　　With the popularization of green and environmental protection concepts, clean energy has become a hot spot for development. In the course of many years of commercialization, lithium batteries have been favored by the electric vehicle industry and the electronics industry for their strong endurance, clean energy carrier, and high power tolerance. As the core material of lithium batteries, separators have huge development potential and provide important material resources to promote the development of the new energy automobile industry in the future. At present, the extensive expansion path of my country's CR1620 battery industry has weakened the technological innovation of key materials. If my country wants to occupy a place in the fierce international game, it must continue to innovate from the source and accelerate the design and layout of key materials. This brings the diaphragm industry into a great leap forward stage.

　　The author believes that in order to alleviate the pressure on energy and environment, electric vehicles have become the main strategic direction to effectively promote the transformation of automobiles. Therefore, the overall technology of power batteries and key components has become the focus of research and development. It is necessary to implement technological innovation projects and cultivate new economic growth. Point, to establish a research and development system, lithium-ion batteries must be used as core components, and the separator industry, as an important link in the entire industrial chain, is of great strategic significance. The CR1620 battery separator has very strict technical requirements and is the last of the four key components of my country's lithium batteries to be domestically produced. Its related patents have always been monopolized by the United States and Japan, and my country's CR1620 battery production is also highly dependent on it. , therefore the development of industrialization, coverage of the mid-to-low-end market and research and development of the high-end market have become very important.

　　From the current point of view, the localization of separators has shown a gratifying situation. The production capacity of some separators is expanding, the quality is improving, the production process is gradually stabilized and optimized, and most of the imported products have been replaced in the low- and mid-end markets, and a small number of products have been Entering the high-end market, and the price advantage of domestic diaphragms has also been revealed. These diaphragm products and services of different levels and functions have been recognized by users, and the market share has steadily increased. However, under the favorable situation, China Battery Network believes that the future development focus of my country's CR1620 battery separator industry is not industrialization, but targeted research and development based on changes in market demand. Although the development of clean energy can bring a new round of development opportunities, after foreign diaphragm manufacturers establish production bases in China to expand production, production capacity will far exceed market demand, and a surplus crisis is inevitable. Therefore, enterprises must have a clear understanding of this. While gradually upgrading production processes, they must also make their own advantages under the planning of market segments, so as to conduct research and development according to changes in market demand and be targeted.

　　Nowadays, there is also some homogeneous competition in the domestic separator industry, which will inevitably lead to a decline in the market mechanism and a reshuffle of the industry. However, most domestic companies are still unable to join the supply system of the world's mainstream battery manufacturers. Therefore, the company's design The production capacity structure must adapt to the structure of market demand. In the field of research and development, we must create customer needs with an international perspective, achieve the goal of transitioning to a high-end industrial form, and achieve efficient and stable healthy operation of the industry.
