Abstract
A lithium air battery including: a negative electrode including lithium; a positive electrode using oxygen as a positive active material; and an organic electrolyte, wherein the organic electrolyte includes a metal-ligand complex.
Claims26
A lithium air battery comprising:
- a negative electrode including lithium;
- a positive electrode using oxygen as a positive active material;
- and
- an organic liquid electrolyte,
- wherein the organic liquid electrolyte comprises a transition metal-ligand complex which is configured to participate in electron transfer during charging and/or discharging,
- wherein the metal-ligand complex has a redox potential of about 2 V to about 5 V with respect to lithium metal,
- wherein the ligand of the metal-ligand complex comprises a haptic ligand, or a polydentate ligand with at least two coordination sites, and
- wherein the metal of the metal-ligand complex is at least one metal selected from the group consisting of vanadium (V), chromium (Cr), manganese (Mn), nickel (Ni), copper (Cu), niobium (Nb), molybdenum (Mo), ruthenium (Ru), tungsten (W), platinum (Pt), silver (Ag), gold (Au), palladium (Pd), and rhodium (Rh).
