Rechargeable electrolysis cell
View Patent ↗A rechargeable electrolysis cell includes: an anode; a cathode; an electrical connection; and an electrolyte. The cathode has an inlet for an oxidizer. The reducing agent is a solvated metal ligand, a Birch electron, a solvated electron, metal salt, or a metallic plating on the cathode. The oxidizer is a halogen. A method of discharging the cell includes providing the reducing agent at the anode and delivering the oxidizer to the cathode and transferring an electron from the anode through an electrical load, oxidizing the reducing agent and reducing the oxidizer to produce a salt dissolved in the electrolyte. Charging the cell includes applying direct current to convert the salt to the reducing agent and the oxidizer and separating the reagents.
1. A method of charging and discharging a rechargeable electrolysis cell, comprising:
a) providing a rechargeable electrolysis cell, comprising:
i) an anode;
ii) a cathode having an inlet for an oxidizer;
iii) an electrical connection between the anode and the cathode;
iv) an electrolyte; and
v) a reducing agent selected from the group consisting of a solvated metal ligand, a solvated electron, metal crystal, and a metallic plating on the cathode;
wherein the oxidizer is a halogen;
wherein discharging comprises:
b) providing the reducing agent at the anode and delivering the oxidizer to the cathode; and
c) transferring an electron from the anode to the cathode by way of the electrical connection through an electrical load, such that the reducing agent is oxidized and the oxidizer is reduced, producing a salt dissolved in the electrolyte; and
wherein charging comprises:
d) applying a direct current to convert the salt to the reducing agent and the oxidizer; and
e) separating the reducing agent and the oxidizer.
2. The method of charging and discharging a rechargeable electrolysis cell of claim 1 , further comprising:
a) sensing a concentration of the salt dissolved in the electrolyte to determine if saturated electrolyte is produced; and
b) transferring the saturated electrolyte into a first storage tank.
3. The method of charging and discharging a rechargeable electrolysis cell of claim 2 , further comprising:
a) transferring the saturated electrolyte from the first storage tank into a secondary electrolysis cell before applying the direct current; and
b) transferring the separated reducing agent to a second storage tank and transferring the separated oxidizer to a third storage tank.
4. The method of claim 1 , wherein the solvated electron is a Birch electron.
