Voltage-enhanced energy storage devices
First Claim
1. An energy storage device comprising at least one electrochemical cell, comprising:
- a first electrode that, in a charged state of said at least one electrochemical cell, comprises an alkali or alkaline earth metal;
an electrolyte in electrical communication with said first electrode, wherein said electrolyte conducts charged species of said alkali or alkaline earth metal; and
a second electrode in electrical communication with said electrolyte, wherein said second electrode comprises a metal or metalloid;
wherein (i) in a discharged state of said at least one electrochemical cell, said second electrode is substantially free of said alkali or alkaline earth metal, or (ii) in a charged state of said at least one electrochemical cell, said electrolyte comprises charged species of said metal or metalloid, and wherein at least two of said first electrode, said second electrode, and said electrolyte are in a liquid state at a temperature of at least about 100°

Abstract
The present disclosure provides an energy storage device comprising at least one electrochemical cell comprising a negative current collector, a negative electrode in electrical communication with the negative current collector, an electrolyte in electrical communication with the negative electrode, a positive electrode in electrical communication with the electrolyte and a positive current collector in electrical communication with the positive electrode. The negative electrode comprises an alkali metal. Upon discharge, the electrolyte provides charged species of the alkali metal. The positive electrode can include a Group IIIA, IVA, VA and VIA of the periodic table of the elements, or a transition metal (e.g., Group 12 element).
