Abstract

Ordered mesoporous TiC-C (OMTC) composites were prepared and served as catalysts for nonaqueous Li-O2 batteries. The OMTC cathodes showed high specific capacity, low overpotential and good cyclability. Furthermore, the reaction mechanism of Li-O2 batteries during charge and discharge processes was investigated extensively by XRD, XPS and in situ GC-MS methods.
