A reversible electrode is provided comprising mainly organic disulfide compounds and having applications in such electrochemical devices as batteries, electrochromic displays, sensors, memories, etc. Large current charge/discharge is realized at room temperature with charge/discharge characteristics of excellent reversibility. Its structure is a composition combining organic disulfide compounds with disulfide bonding and conducting polymers. In other words, conducting polymers after being subjected to an electrolysis are put together with organic disulfide compounds. Thus, due to the effect of composition with conducting polymers, the oxidation/reduction reactions of organic disulfide compounds are accelerated and a reversible electrode characterized by utilization of a high energy density of organic disulfide compounds and the possibility of a large current charge/discharge is realized.
