COLLECTOR, ELECTRODE STRUCTURE, ELECTRICITY STORAGE COMPONENT, AND COMPOSITION FOR COLLECTORS

摘要

Provided are: a highly safe collector which is capable of stably maintaining a PTC function even in cases where the temperature is further increased after the exhibition of the PTC function if used in an electrode structure of an electricity storage component such as a nonaqueous electrolyte battery, an electric double layer capacitor or a lithium ion capacitor; an electrode structure; an electricity storage component; and a composition for collectors. Provided is a collector (100) which is provided with a conductive base (103) and a resin layer (105) that is provided on at least one surface of the conductive base (103). The resin layer (105) is obtained by applying a paste, which contains polyolefin emulsion particles (125), a conductive material (121) and a crosslinking agent (131), onto the conductive base (103) and crosslinking the paste thereon. The polyolefin emulsion particles (125) contain a polyolefin resin (129) that is modified with a carboxylic acid or a carboxylic acid anhydride at both ends.
