ELECTROCHEMICAL STORAGE MATERIAL AND ELECTROCHEMICAL STORAGE DEVICE FOR STORING ELECTRICAL ENERGY, COMPRISING SUCH STORAGE MATERIAL
To provide a metal/metal oxide high-temperature storage device which has long-term stability and also shows very little storage loss even after discharging and charging cycles of more than 1,000 times.SOLUTION: A storage material has a reactive framework structure which is capable of chemically integrating, in addition to at least one reduced and/or oxidized active component, at least one form of an active component in the form of a mixed oxide or an alloy into the framework structure during charging or discharging process. A coarsening or permanent separation of the storage material can be prevented in that the active component of the storage material can be taken up, completely or to a large extent, in a reactive framework structure of the storage material during the charging or discharging process. In an oxidic framework structure, at least one stable mixed oxide consisting of the active component and an oxide from the framework structure is formed. In the metallic framework structure, the integration is achieved by forming an alloy of active components and at least one metal of the framework structure.SELECTED DRAWING: None
【課題】長時間安定であり、１０００回を超える放電−および充電サイクル後にも貯蔵体損失を示さない金属／金属酸化物高温貯蔵デバイスを提供する。【解決手段】貯蔵材料が、少なくとも１つの還元型および／または酸化型の活性成分の他に、充電または放電過程の間に少なくとも１つの形の活性成分を混合酸化物または合金の形態で化学的に骨格構造内に組込むことができる反応性骨格構造を有し、貯蔵材料の粗大化もしくは持続的分離が、充電または放電過程の間に、貯蔵材料の活性成分を、貯蔵材料の反応性骨格構造内に完全にまたは大部分をその中に吸収することができることによって妨げられる。酸化物骨格構造においては、活性成分と、骨格構造からの酸化物とからなる少なくとも１つの安定な混合酸化物を形成し、金属骨格構造においては、組込みは、活性成分と、骨格構造の少なくとも１つの金属とからなる合金を形成することにより達成される。【選択図】なし
