摘要： 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.
