Composite particle for electrode and process for producing thereof, electrode and process for producing thereof, and electrochemical element and process for producing thereof

摘要

The composite particle for an electrode in accordance with the present invention contains an electrode active material, a conductive auxiliary agent having an electronic conductivity, and an oxidizing/reducing agent. Therefore, this composite particle can construct an effective conductive network, and effectively provide so-called oxidizing/reducing capacity due to the oxidizing/reducing agent. Hence, when the composite particle for an electrode in accordance with the present invention is used as a constituent material of an electrode in an electrochemical device, the electrochemical device can realize a higher capacity.
