Recently, the Zhejiang Provincial People's Government issued a decision to commend the winners of the 1st Zhejiang Province Intellectual Property Award, announcing the list of winners. The core invention patent of Zhuhai Blue Sky Polyvinylidene Fluoride (PVDF) product, "High Adhesive Polyvinylidene Fluoride Copolymer," was awarded the first prize for invention patents.
"High Adhesive Polyvinylidene Fluoride Copolymer" addresses the long-term reliance on imported high-performance PVDF binders for lithium batteries and the foreign monopoly on intellectual property. We independently developed a new type of PVDF copolymer, with better adhesion and alkali resistance than foreign competitors. This has led to integrated technological innovation in polymerization, processing, application, and industrialization. Expert reviews have confirmed that the technology has reached international leading levels. This intellectual property achievement has been successfully implemented and mass-produced on a thousand-ton production line, supplying global lithium battery giants. The product has been adopted by the top 20 companies in the lithium battery industry, creating significant social and economic benefits and effectively promoting the technological progress of China's fluorine chemical industry.
The Zhejiang Province Intellectual Property Award is the first provincial government comprehensive intellectual property award established nationwide. It is the only provincial government award in the field of intellectual property that covers all categories of intellectual property and the entire chain of "creation, operation, and protection." The evaluation is organized by the Zhejiang Market Supervision Administration (Zhejiang Intellectual Property Office).
