COLLECTOR, ELECTRODE STRUCTURE, NONAQUEOUS ELECTROLYTE CELL, AND ELECTRICITY STORAGE COMPONENT

摘要

Provided is a current collector which has a PTC layer having room for thermal expansion at elevated temperature while securing sufficient conductivity at normal temperature. According to the invention, a current collector comprising a conductive base material, and a resin layer formed on at least one surface of the conductive base material is provided. The resin layer contains an organic resin and conductive particles. A deposition amount of the resin layer on the conductive base material is 0.5 to 20 g/m 2 . Rz (ten point average roughness) of the surface of the resin layer is 0.4 to 10 µm. Sm (average spacing of ruggedness) of the surface of the resin layer is 5 to 200 µm. An average of resistance of the resin layer measured by the two-terminal method is 0.5 to 50 ©.
