Abstract
Performance, properties and stability of bifunctional air electrodes may be improved by using modified current collectors, and improving water wettability of air electrode structures. This invention provides information on creating non-corroding, electrically rechargeable, bifunctional air electrodes. In some embodiments, this bifunctional air electrode includes a corrosion-resistant outer layer and an electrically conductive inner layer. In some embodiments, this bifunctional air electrode includes titanium suboxides formed by reducing titanium dioxide. Titanium suboxides may be corrosion-resistant and electrically conductive.
