Abstract
An object of the present invention is to provide a current collector which can decrease the internal resistance of a non-aqueous electrolyte battery, be used suitably for a non-aqueous electrolyte battery such as a lithium ion secondary battery and the like or for an electrical storage device such as a lithium ion capacitor and the like, and improve high rate characteristics. According to the present invention, a current collector which is structured by forming a resin layer possessing conductivity on at least one side of a conductive substrate is provided. The resin layer contains a chitosan-based resin and a conductive material, and the water contact angle of the surface of the resin layer measured by θ/2 method in a thermostatic chamber at 23° C. is 5 degrees or more and 60 degrees or less. In addition, an electrode structure, a non-aqueous electrolyte battery, and an electrical storage device which use the current collector are provided.
