Abstract:
A composition comprising: a metal oxide of a first metal ions and second metal ions; an electrically conductive material; and a binder material. The second metal ions have a higher oxidation state than the first metal ions. The presence of the second metal ion increases the number of metal cation vacancies. A method of: dissolving salts of a first metal ion and a second metal ion in water to form a solution; heating the solution to a temperature of about 80-90° C.; and adding a base to the solution to precipitate nanoparticles of a metal oxide of the first metal ion and the second metal ion.
