Electric storage device electrode and method for manufacturing same

摘要

A method of manufacturing an energy storage device electrode in which breakage of electrode particles and warping of a collector are reduced, and internal resistance is lowered by lowering the contact resistance between the collector and an electrode layer. The method manufactures an electric double-layer capacitor electrode, and includes: forming a plurality of grooves that run in one direction in each of a front surface and rear surface of a collector foil; subsequently providing an electrode layer that includes plural electrode particles on each of the front surface and rear surface of the collector foil; and subsequently pressing the electrode layer toward the collector foil to move the plurality of electrode particles along the plurality of grooves until the plural electrode particles dig into the plurality of grooves.

1. A method of manufacturing an energy storage device electrode, comprising:
forming a plurality of grooves in a surface of a collector, wherein each of the grooves is elongated in one direction such that a longitudinal axis of each of the grooves is parallel to the surface of the collector and is shaped so that the respective groove is wider at one end of the respective groove than at another end of the respective groove in the one direction; subsequently providing an electrode layer, which comprises a plurality of electrode particles, on the surface of the collector; and subsequently pressing the electrode layer toward the collector to move the plurality of electrode particles along the plurality of grooves from the one end toward the another end until the plurality of electrode particles dig into the plurality of grooves.
