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.

Abstract: A communications cable is provided that includes a pair of twisted pair of wires, each coated with a fluoropolymer insulator. The twisted pair of wires is configured to carry a differential signal, such as a differential data signal and/or a differential power signal. The fluoropolymers are highly effective insulators and significantly reduce both the effects of internal and external electromagnetic interference while maintaining low cable attenuation, even when operating within a temperature range of −40° C. to 150° C.
