    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.
