METHOD AND SYSTEM FOR STORING ELECTRICITY IN METALS

摘要

A method for operating an electrochemical cell system for storing electrical energy in metallic material comprising a cell housing containing an electrolyte, a metallic material, a charging assembly for deposition of the metallic material, a discharging assembly for dissolution of the metallic material, and a space for storing the metallic material. The method comprises determining the metal concentration in the electrolyte and a software algorithm for determining the operation parameters such as the currents and voltages of the system as well as the schedules for electrolyte circulation and dislodging of deposited metallic materials.
