Introduction to the development trend of lithium battery separator equipment industry

The localization of lithium battery diaphragm equipment is accelerating, and market competition is gradually transitioning from price competition in the past to performance and technology competition. For the company, new processes and differentiated equipment positioning will become an important trend of market differentiation in the equipment field. With the changes in the demand for lithium batteries and lithium battery separators in the downstream consumer electronics, power vehicles, and energy storage industries, and the development of the lithium battery separator industry itself, the requirements for battery capacity, performance, stability, and safety are getting higher and higher. The higher the accuracy and process requirements, the more investment in lithium battery diaphragm equipment. Lithium battery separator processing equipment is becoming more sophisticated and complex, creating a good market demand for domestic equipment manufacturing companies. ▲Improve the product yield and enhance the heat resistance of the separator. With the advancement of technology and social development, safety issues will inevitably receive more and more attention from the society. In the process of charging and discharging, the separator can still maintain the separator after a large area of u200bu200bpositive and negative electrodes are short-circuited. The integrity of the high-temperature resistant composite diaphragm is bound to be favored by the market. In order to improve the safety of lithium batteries, coating nanomaterials such as ceramics on polyolefin separators or adopting new matrix materials has become a future technology development trend. ▲Improve the thermal shrinkage performance of the separator When the temperature of lithium batteries increases due to long-term use or abnormal conditions, the lithium battery separator should have a certain degree of thermal stability to continue to function as a separator between the positive and negative electrodes. The thermal stability of the separator is determined by the thermal shrinkage rate. If the thermal shrinkage rate of the separator is too high, it will cause the positive and negative materials to contact and cause the battery to short-circuit. ▲Develop ultra-thin diaphragms to improve unit energy density. With the development of the market, lighter, thinner and smaller 3C electronic products will continue to enter our lives. Such products require thinner lithium battery diaphragms to make batteries. At the same time, lithium batteries The pursuit of capacity also requires the development of thin films, but the processing and preparation of ultra-thin diaphragms requires high equipment and technology. The lithium battery diaphragm equipment manufacturing industry is a non-standardized high-end equipment industry, and the performance of the equipment should be continuously improved and perfected according to the changes in customer processing technology and the progress of new materials and new technologies.
