▎ 摘  要

Transition metal oxide nanomaterials have been applied in developing high capacity lithium ion batteries. However, transition metal oxide nanomaterials have some major issues to be addressed, including nanomaterials aggregation, severe side reactions and low conductivity. Herein, multiporous NiMnO3 micro-nano structure spheres are been synthesized, and their composites with graphene sheets (GNSs) have been prepared. The obtained multiporous NiMnO3 micro-nano structure graphene composites show excellent electrochemical performances with a high reversible capacity of 582 mA h g(-1) at a current of 1 A g(-1) after 150 cycles and 914 mA h g(-1) at a current of 0.1 A g(-1) after 50 cycles without obvious side reaction. The result shows the multiporous NiMnO3-GNSs micro-nano structure spheres can alleviate the side reaction of electrolyte. (C) 2017 Elsevier B.V. All rights reserved.
