Abstract

The application of MnCo₂O₄ (MCO) decorated Ti₄O₇ as a carbon-free cathode for Li–O₂ batteries is reported for the first time. The high performance of Ti₄O₇/MCO cathode is attributed to the high electronic conductivity of Ti₄O₇, the high electrocatalytic activity of MCO and the synergistic interaction between Ti₄O₇ and MCO toward ORR and OER.
