摘要： This application relates to the field of battery technologies, and in particular, to a binder and a preparation method thereof, and a separator, electrode assembly, battery cell, battery, and electric apparatus containing such binder. The binder includes a core layer structure and a shell layer structure provided on a surface of the core layer structure, where the core layer structure includes a polyacrylate polymer, and the shell layer structure includes a polyvinylidene fluoride polymer. Polyvinylidene fluoride is a homopolymer with a crystallinity of about 50%, resulting in insufficient adhesion force. Therefore, in this application, the polyvinylidene fluoride polymer is used to encapsulate the polyacrylate polymer to obtain the core-shell-structured binder, so that the crystallinity of the polyvinylidene fluoride polymer in the core-shell-structured binder is improved, and adhesion performance of the core-shell-structured binder is improved, thereby increasing adhesion force between a separator and an electrode plate by the binder.

摘要： A curable composition that includes an amorphous, peroxide-curable fluoropolymer having a first solubility parameter, a solvent having a second solubility parameter, and a peroxide. The amorphous, peroxide-curable fluoropolymer is present from 60 percent to 97.5 percent by weight versus the weight of the curable composition, and the solvent is present from 1 percent to 39 percent by weight versus the weight of the curable composition. The absolute value of the first solubility parameter minus the second solubility parameter is less than or equal to 8.2 (MPa)1/2. The solvent may have a solubility parameter in a range from 9.6 (MPa)1/2 to 26 (MPa)1/2. Methods of making a cured fluoroelastomer from the curable composition are also disclosed.

摘要： The present invention aims to provide a method of producing a fluoropolymer, especially a fluoropolymer essentially including a tetrafluoroethylene or chlorotrifluoroethylene unit, at a higher polymerization rate with improved efficiency, the method being capable of improving the moldability in extrusion molding and suppressing discoloration. The method of producing a fluoropolymer of the present invention includes producing a fluoropolymer by polymerizing tetrafluoroethylene or chlorotrifluoroethylene in the presence of a peroxydicarbonate. The peroxydicarbonate is represented by the formula:

R-O-C(=O)-O-O-C(=O)-O-R

wherein R's may be the same as or different from each other and individually represent a C4 alkyl group or alkoxy alkyl group.
