Abstract
A current collector is disclosed and comprises a conductive material and an elemental metal of a group 6 metal contacting the conductive material. Also disclosed are an electrochemical cell comprising a current collector, a cathode adjacent to the current collector, and an alkali metal-based electrolyte between the current collector and the cathode, with the cathode separated from the group 6 metal by the alkali metal-based electrolyte. A method of operating the electrochemical cell is also disclosed.

A current collector comprising:
- a conductive material;
- and
- an elemental metal of a group 6 metal contacting the conductive material.
An electrochemical cell comprising:
- a current collector comprising a group 6 metal on a conductive material;
- a cathode adjacent to the current collector;
- and
- an alkali metal-based electrolyte between the current collector and the cathode, the cathode separated from the group 6 metal by the alkali metal-based electrolyte.
A method of operating an electrochemical cell, comprising:
- forming an electrochemical cell comprising a current collector comprising a conductive material and a group 6 metal thereon, an alkali metal-based electrolyte on the current collector, and a cathode on the electrolyte;
- cycling the electrochemical cell to form the alkali metal on the current collector;
- and
- discharging the electrochemical cell to remove the alkali metal from the current collector.
