SOL-GEL APPROACHES FOR SOLID ELECTROLYTES AND ELECTRODE MATERIALS

Sol-gel chemistry has a great many potential applications in the prepa ration of unique electrochemical materials, from non-equilibrium trans ition metal oxides which may be of use as high energy density electrod es, to high surface area mixed oxides which may possess high proton co nductivity, to novel composite structures consisting of inorganic gels in combination with organic electronic and ionic conductors. This pap er reviews prior work on proton conduction in gel systems and presents recent work regarding electrode materials prepared by sol-gel methods and inorganic-organic materials.
