Abstract

Mesoporous TiO₂ with well-distributed RuO₂ catalysts is considered in this paper as a carbon-free cathode material replacement. Benefiting from the highly-porous TiO₂ support structure and high catalytic activity of RuO₂, the Li-O₂ cells with composite RuO₂/mesoporous TiO₂ cathodes show low charge potentials with a high cell capacity. The stability of the TiO₂ materials was verified by investigating stable cell performance as well as through structural and chemical characterization via X-ray diffraction and X-ray photoelectron spectroscopy. This study demonstrates the possibility of achieving high energy at the cell level, free of carbon instability.
