Abstract
An electrochemical cell includes solid-state, printable anode layer, cathode layer and non-aqueous gel electrolyte layer coupled to the anode layer and cathode layer. The electrolyte layer provides physical separation between the anode layer and the cathode layer, and comprises a composition configured to provide ionic communication between the anode layer and cathode layer by facilitating transmission of multivalent ions between the anode layer and the cathode layer.
Claims20
An electrochemical cell, comprising
- an anode layer;
- a cathode layer;
- and
- a printed non-aqueous gel electrolyte layer coupled to the anode layer and the cathode layer;
- said gel electrolyte layer providing physical separation between the anode layer and the cathode layer;
- said gel electrolyte layer comprising a polymer into which at least one ionic liquid and an electrolyte salt have been imbibed, said gel electrolyte layer having an amount of said at least one ionic liquid not exceeding 75 wt. %;
- and
- said gel electrolyte layer comprising a composition configured to provide ionic communication between the anode layer and cathode layer by facilitating transmission of multivalent ions between the anode layer and the cathode layer, wherein the electrolyte salt dissolved into the ionic liquid releases multivalent cations selected from ions of at least one of zinc, aluminum, magnesium and yttrium.
An electrolyte configured to provide physical separation between an anode and a cathode of an electrochemical cell, comprising:
- a room temperature ionic liquid electrolyte comprising an ionic liquid and a dissolved salt, said ionic liquid electrolyte imbibed into a polymer to form a printable non-aqueous gel, and said ionic liquid electrolyte having a concentration of said dissolved salt between 0.3 M and 0.75 M;
- the electrolyte comprising a composition configured to provide ionic communication between the anode and the cathode by facilitating transmission of multivalent ions across the electrolyte, wherein the dissolved salt releases multivalent cations selected from ions of at least one of zinc, aluminum, magnesium and yttrium.
