▎ 摘  要

NOVELTY - Preparing cathode comprises (i) coating the deposition primer slurry on the surface of the fibrous cathode collector, and drying to obtain cathode collector with a conductive primer, where, the primer slurry includes a conductive material, polyvinylidene fluoride and N-methylpyrrolidone with a mass ratio of 1-3:0.5-2100-200, where the fibrous cathode current collector includes copper wire; the conductive material includes conductive carbon black, carbon nanotubes, and/or graphene, and (ii) coating and depositing the cathode slurry, and drying to obtain the cathode fiber, which is the cathode. USE - The cathode is useful in flexible fibrous woven lithium-ion battery (claimed). ADVANTAGE - The cathode contact current collector and active substance is improved, reducing the internal resistance, so as to improve the multiplying power of the battery. The method is simple and fast, convenient for industrial application, and provides a new possibility for development of flexible fibrous woven lithium-ion battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a cathode, prepared by the above method; and use of cathode in flexible fibrous woven lithium-ion battery.
