PVDF dominant disrupter
After batches of enterprises study one after another, this situation is expected to achieve a subversive breakthrough, PVDF's dominant position in the field of lithium battery cathode is being shaken by a homegrown Kechuang company, The company is Shenzhen Research New Materials Co., LTD., which was founded in 2019 in Shenzhen.
It is understood that a company subversive (subversion of the existing PVDF system) to the new PI class materials applied to lithium electric functional materials (instead of PVDF used for binder, edge coating, positive and negative electrode functional additives, diaphragm coating adhesive), has become the industry's first is also a PI class materials real commercial application in the field of lithium battery enterprises. Up to now, the company has successfully developed the ZONE series of products. At present, the positive electrode side coating ZONE12S and the positive electrode binder ZONE80 of the ZONE series of products have been mass produced and shipped in batches, and are highly recognized by the top downstream lithium battery enterprises at home and abroad.
According to the founder of Yayan company, the positive side coating ZONE12S is a subversive, unique and economical product, it is the industry's first non-fluorine positive side coating material, with its excellent performance and comprehensive cost performance have the ability to completely overturn the existing PVDF system, and break the PI material high cost cognition, Let the customer use affordable, practical perception of its value.solve PVDF many pain points, broad application prospects
research a project leader said, in the field of lithium battery cathode side coating, PVDF has been applied for many years, the technology is relatively mature, but its shortcomings are also very obvious, the most obvious shortcoming is poor peeling strength, After soaking the electrolyte for a long time, there will be spalling phenomenon, there is a certain safety hazard; In contrast, the peel strength of ZONE12S developed and produced by Yanyi Company is more than 10 times higher than that of PVDF (the gel formula is adhesive: ceramic particle = 15:85, 180° peel test result of universal tensile testing machine), and the bond performance is stable after immersion in electrolyte, which can ensure long-term safety.
Not only that, the ZONE12S developed and manufactured by Yanyi Company also has the advantages of outstanding customer value, environmental protection, easy mass production, independent intellectual property rights and so on, which can effectively solve many pain points of customers. In terms of cost, ZONE12S uses a subversive original production process, which makes the raw material cost of ZONE12S products lower than PVDF, with better economy; In terms of environmental protection, no "three wastes" are produced in the production process of ZONE12S. The whole process is green and environmentally friendly, and there is no restriction of environmental protection policies. In terms of production capacity, the current ZONE12S glue liquid production capacity of Yanyi Company is sufficient, fully able to meet the needs of the side coating field, there is no production bottleneck problem; In terms of intellectual property, Yanyi Company has a complete intellectual property layout of materials and application processes, so customers have no worries in terms of intellectual property when using this product. This project is developed in cooperation with the team of senior Japanese PI product development experts, Professor Xu Jiarui and Professor Zhang Yi from Sun Yat-sen University. Professor Xu and Professor Zhang have been engaged in PI material development for more than 20 years and have extremely rich experience and technical reserves in PI material development.Another bigger disadvantage of PVDF is that after years of development, the space for structural improvement has already met the bottleneck, unable to meet the performance requirements of the new lithium battery system, and there is a certain drag on the technological progress of the entire lithium battery industry. In contrast, ZONE12S is also a new type of lithium battery functional material. Due to the characteristics of PI itself, there is still a huge room for improvement in the structure, and the future prospect is broader. This project is developed in cooperation with the team of Professor Xu Jiarui and Professor Zhang Yi from Sun Yat-sen University. Professor Xu and Professor Zhang have been engaged in PI material development for more than 20 years and have rich experience in PI material development.
From the feedback results of the market, ZONE12S as a new positive electrode edge coating has irreplaceable excellent performance and low use cost (acceptable price), is one of the best choices for the next customers, especially in the guarantee of lithium battery safety performance of the importance is self-evident, ZONE12S is expected to be widely used in the field of power battery and energy storage battery, and the market prospect is promising.
< /p>As a scientific and creative enterprise, Yanyi Company has determined the mission of "create the first, create the future" since its establishment, and is committed to becoming a disrupter and leader in the field of lithium electric functional materials. ZONE series products, after several years of dedicated research and development, have been successfully released and recognized by customers, which is the perfect interpretation of Yanyi company's "create the first, create the future".
