Optionally, electrodes may comprise a mixture of multiple metals or metal containing compositions. Such a mixture may correspond to an alloy or a mixture of metal oxides, metal sulfides, metal nitrides, metal chlorides, metal hydrides, etc. By combining multiple metals, an increase in certain properties (e.g., capacity, conductivity) may be realized. For example, a combination of cobalt oxide and nickel oxide, such as may be referred to as nickel cobaltite, may correspond to a material that exhibits an electrical conductivity greater than either nickel oxide or cobalt oxide taken alone. Such an increase in electrical conductivity may be up to 100×-500× greater than the individual oxides.
Optionally, electrodes may be independently fabricated using controllable deposition methods. Useful deposition techniques include, but are not limited to, atomic layer deposition, magnetron sputtering, spin deposition, thermal evaporation, and chemical vapor deposition. Other fabrication techniques useful for fabricating the electrodes may include or involve other techniques, such as ultraviolet lithography, x-ray lithography, holographic lithography, laser ablation, and thermal evaporation.
