Battery with an anode preload with consumable metals

摘要

A method is provided for fabricating a battery using an anode preloaded with consumable metals. The method forms an ion-permeable membrane immersed in an electrolyte. A preloaded anode is immersed in the electrolyte, comprising MeaX, where X is a material such as carbon, metal capable of being alloyed with Me, intercalation oxides, electrochemically active organic compounds, and combinations of the above-listed materials. Me is a metal such as alkali metals, alkaline earth metals, and combinations of the above-listed metals. A cathode is also immersed in the electrolyte and separated from the preloaded anode by the ion-permeable membrane. The cathode comprises M1YM2Z(CN)N.MH2O. After a plurality of initial charge and discharge operations are preformed, an anode is formed comprising MebX overlying the current collector in a battery discharge state, where 0≦b

1. A method for fabricating a battery using an anode preloaded with consumable metals, the method comprising:
forming an electrolyte; forming an ion-permeable membrane immersed in the electrolyte; forming preloaded anode immersed in the electrolyte, comprising MeaX, where X is a material selected from the group consisting of carbon, metal capable of being alloyed with Me, intercalation oxides, electrochemically active organic compounds, and combinations of the above-listed materials, and Me is a metal selected from the group consisting of alkali metals, alkaline earth metals, silver (Ag), aluminum (Al), and a combination of the above-listed metals; forming a cathode immersed in the electrolyte and separated from the preloaded anode by the ion-permeable membrane, where the cathode comprises M1YM2Z(CN)N.MH2O;
where M1 and M2 are independently selected from the group consisting of transition metals, calcium (Ca), magnesium (Mg), strontium (Sr), and barium (Ba);where Y is less than or equal to 1;where Z is less than or equal to 1;where N is less than or equal to 6;where M is less than or equal to 20; performing a plurality of initial charge and discharge operations, where a charge operation uses an external power source to create a current from the preloaded anode to the cathode, and a discharge operation connects an external load between the preloaded anode and cathode; and, forming an anode comprising MebX overlying the current collector in a battery discharge state, where 0≦b
