Abstract
An iron-silver battery is made, comprising at least one positive silver electrode plate; at least one negative iron electrode plate; and at least one shunt electrode connected to and electrically in parallel with the positive plate comprising a material having a lower oxygen evolution potential than silver, each separated from the other by a material that is not chemically attacked by electrolyte solution, and all housed in a case containing an electrolyte solution.
Claims10
An iron-silver battery comprising a case within which are disposed:
- (1) at least one positive electrode plate comprising:
- (a) a porous plaque comprising silver active electrode material,
- (b) an electrical lead tab attached to the electrode,
- (2) at least one negative electrode plate comprising:
- (a) a porous, electrode structure comprising iron active material,
- (b) an electrical lead tab attached to the electrode,
- (3) at least one shunt electrode connected to and electrically in parallel with the positive electrode plate comprising:
- (a) a porous structure comprising a material having a lower oxygen evolution potential than silver,
- (b) an electrical lead tab attached to the shunt electrode,
- (4) a separator between the positive and negative plates and between the plates and the shunt electrode;
- (5) an electrolyte solution;
- and
- (6) means for making electrical connections to the plates in a manner such that the positive plate and the shunt electrode are connected to a positive terminal, and the negative plate is connected to a negative terminal.
