Abstract
Ion transport in electrochemical cells or energy storage devices may take place in metal salt-based electrolytes. The metal salt-based electrolytes may comprise high doping metal salt formulations. Electrochemical cells or energy storage devices comprising metal salt-based electrolytes may be used as single-use or rechargeable power sources.
Claims20
An electrochemical cell, comprising:
- a positive electrode;
- a negative electrode;
- and
- a printed electrolyte between the positive electrode and the negative electrode, the printed electrolyte comprising:
- an ionic liquid comprising at least one anion selected from the group consisting of bis(fluoromethanesulfonyl) imide, bis(fluorosulfonyl) imide, bis(trifluoromethanesulfonyl) imide, triflate, trifluoromethanesulfonate, and tetrafluoroborate;
- and
- a metal salt that releases multivalent cations when dissolved in the ionic liquid;
- wherein the multivalent cations are selected from at least one of zinc, aluminum, magnesium, and yttrium;
- wherein the molarity of the multivalent cations in the ionic liquid is greater than 1 molar (M);
- wherein the electrochemical cell is rechargeable.
