Electrochemical system for storing electricity in metals

摘要

An electrochemical system for storing electrical energy in metallic material comprises a charging assembly having one or more cathode and anode couples for metal deposition and a discharging assembly having one or more cathodes and spaces amid the cathodes for containing metal anode. The charging assembly and discharging assembly are physically separated allowing independent operation of the charging and discharging facilities and independent scaling of power and energy capabilities. It also allows storage of anode metal material in simple containers separated from the charging and discharging assemblies and thus allows for economical energy storage.

1. An electrochemical cell system, comprising:
a housing; an electrolyte disposed in the housing; a metallic material; a plurality of charging anodes and a plurality of charging cathodes at least partially immersed in the electrolyte; a plurality of discharging cathodes immersed in the electrolyte; and a plurality of first spaces adjacent the discharging cathodes, wherein:
the housing is a single container and the plurality of charging cathodes, the plurality of charging anodes, the plurality of discharging cathodes and the plurality of discharging anodes are all housed within the single container;the charging cathodes and charging anodes are above the discharging cathodes;the metallic material is electrochemically deposited on the charging cathodes during charging;the metallic material deposited on the charging cathodes is at least intermittently dislodged;the metallic material, when positioned in the first spaces, forms a plurality of discharging anodes; andthe metallic material is electrochemically dissolved during discharging.
