Abstract

Storage material, for storing electrical energy by reduction or oxidation of an active component, comprises the active component in at least a reduced and/or oxidized form and a reactive framework structure that is capable of chemically integrating at least one form of the active component in the form of a mixed oxide or an alloy into the reactive framework structure during the charging or discharging process. In the case of an oxidic framework structure, said integration can occur by formation of at least one stable mixed oxide of the active component and an oxide from the framework structure. In the case of the metallic framework structure, said integration can occur by forming an alloy of active component and at least one metal of the framework structure.
