Abstract
The present disclosure relates to an electrochemical cell which may be used, for example, in a rechargeable battery based on the reversible transfer of halide anions, and a method for making an electrolyte composition for use in the same. The electrochemical cell includes a positive electrode, a negative electrode, and an electrolyte composition positioned between the two electrodes, where the electrolyte composition contains a crown ether-metal halide complex in a solvent.
Claims9
A method of making an electrolyte composition, the method comprising:
- (a) dissolving a crown ether and a metal halide in a solvent;
- (b) reacting the crown ether and the metal halide to form a crown ether-metal halide complex;
- (c) isolating the crown ether-metal halide complex;
- and
- (d) adding the crown ether-metal halide complex into a non-aqueous electrolyte solution of a rechargeable battery to provide one or more halide ions in the electrolyte solution, wherein the electrolyte solution comprises at least one organic solvent.
