  • COMPOSITE FLUOROPOLYMER BINDER AND METHODS OF MAKING SAME, COMPOSITE BINDER MATERIAL AND METHOD FOR PRODUCING SAME, ELECTRODE, ENERGY STORAGE DEVICE, BINDER POWDER FOR ELECTROCHEMICAL DEVICE AND METHOD FOR PRODUCING SAME, BINDER FOR ELECTROCHEMICAL DEVICE, ELECTRODE MIXTURE, ELECTRODE FOR SECONDARY BATTERY, AND SECONDARY BATTERY
    Publication number: 20240178399
    Abstract: Composite binder materials for energy storage applications are disclosed. The composite binder materials include a fluoropolymer, such as polytetrafluoroethylene (PTFE), integrated with a conductive additive and a low-melting point thermoplastic. Methods of making the composite binder materials are also disclosed. The methods include providing an emulsion of the fluoropolymer, mixing the low-melting point thermoplastic and the particulate conductive additive into the emulsion of the fluoropolymer to form a mixture, and coagulating the mixture to produce a coagulum including the composite binder material. The disclosure also provides a binder powder for an electrochemical device capable of providing an electrode mixture sheet having excellent uniformity of tensile strength. The disclosure relates to a binder powder for an electrochemical device, containing a non-fibrillated fibrillatable resin and a thermoplastic polymer.
