Both the activity and structure of a cathode, when it is used in non-aqueous Li-O 2 batteries, play a prominent role in the aspects of durability and capacity.In this work, α-MnO 2 /prGO hybrid nanocomposites with a three-dimensional (3D) porous structure are proposed to act as the cathode to improve the battery performance. Highly active α-MnO 2 /prGO nanocomposites with different mass ratios are synthesized through a two-step template method and a subsequent annealing process. It is found that the optimal 50% α-MnO 2 /prGO cathode exhibits outstanding discharge capacity of 13 294 mAh g À1 under the condition of 100 mA g À1 . Meanwhile, with the limited capacity and currency density of 1000 and 100 mA g À1 , respectively, the battery maintains excellent durability for 239 cycles. Significantly, it is clear that the excellent electrochemical performance of the nanocomposites is strongly associated with the synergistic effect of their distinct porous architecture and the ORR/OER catalytic activity.

Abstract2D materials exhibit remarkable electrochemical performance as the cathode catalyst in lithium–oxygen batteries (LOBs). Their catalytic capability mainly derives from their 2D surface with tunable surface chemistry and unique electronic states. Herein, Ti0.87O2 and Ti3C2 MXene monolayers are applied to construct a face/face 2D heterostructure to enhance the catalytic performance in LOBs. It is demonstrated that electronic compensation from the O‐terminated MXene to Ti0.87O2 side is achieved through the built‐in electric field and the overlap of Ti 3d and O 2p orbitals between Ti0.87O2 and MXene units. As a result, the ORR/OER catalytic activity is improved in Ti0.87O2/MXene heterojunction due to the modulated p‐band center that optimizes the s–p coupling with the key intermediate LiO2. The Ti0.87O2/MXene cathode presents a structural stability and long‐term cycling life of 425 cycles (2534 h) at 200 mA g−1 and 407 cycles at 1000 mA g−1 with a fixed capacity of 600 mAh g−1, being nearly five and three times higher than that of pure Ti0.87O2 and MXene cathodes, respectively.
