Through in-depth negotiation, we reached a consensus on in-depth cooperation in the field of solvent coating and isolation film for lithium ion power use of new energy vehicles. Both sides have started substantive cooperation in customer joint development, production equipment efficiency improvement, etc. As the first step to start the strategic cooperation in an all-round way, for the cooperative development project agreed by both parties, Japanese Imperial Co., Ltd. authorizes relevant patents of PVDF series solvent coating material composition and phase separation coating production process to Shanghai Enjie New Material Technology Co., Ltd. Both sides have signed the license contract of relevant patents and will jointly speed up the market development and further expand the scope of business cooperation. Shanghai Enjie New Material Technology Co., Ltd. has a leading competitive advantage in terms of production capacity, cost and quality, and has a complete R & D and manufacturing capacity of water-based and solvent-based coating isolation film. With more than 10 years of deep research and development, production and manufacturing, and quality management capabilities, and a large number of intellectual property rights accumulations around the world, imperial Corporation of Japan is a global leader in product and process R & D, manufacturing and quality management. The cooperation between the two sides can form strong joint advantages and complement each other. Under the premise of win-win cooperation, the two sides can jointly provide high energy density and large capacity lithium-ion batteries with solvent type isolation membrane with superior performance, high safety and high cost competitiveness, and contribute to the sustainable development of new energy automobile industry. In view of the excellent performance of solvent type coating isolation film, it is expected that the proportion of power lithium-ion batteries, especially in soft packs and square lithium-ion batteries, will be greatly increased in the future, with a good market prospect. The results show that compared with the conventional water-based coating technology, the micro structure of the coating processed by the solvent based coating technology is more uniform, better consistency, and stronger adhesion with the lithium battery electrode, which can effectively improve the electrochemical performance, life, safety and processing performance of the lithium battery. Many years ago, solvent coated diaphragms have been used in large quantities on consumer, power and energy storage batteries. In China, they have also been widely used in high-end consumer lithium batteries, and some power battery manufacturers have begun to use them. Solvent coating technology is very difficult. At present, only a few companies in the world have successfully achieved mass production. With the large-scale, long-life and further improvement of energy density of power soft pack battery and square battery, the application of solvent coated membrane will be more and more extensive. The cooperation between Shanghai Enjie New Material Technology Co., Ltd. and Japanese emperor Co., Ltd. will help to further strengthen the market competitiveness of solvent based coating isolation film, meet the company's development strategic objectives, and have a positive impact on improving the company's comprehensive competitiveness, industry influence, business performance, etc.
