Electrochemical performance ofMn(3)O(4)nanorodsby N-doped reduced graphene oxide using ultrasonic spray pyrolysis for lithium storage

Abstract

The crumpled N-doped reduced graphene oxide wrapped Mn(3)O(4)nanorods (Mn-NrGO) composite are synthesized via a combination of spray pyrolysis and a hydrothermal process for lithium ion batteries. The Mn(3)O(4)nanorods are uniformly dispersed in the conductive matrix of crumpled N-doped reduced graphene oxide, forming a uniform wrapped composite and stopping them from restacking, which synergistically enhanced the Li(+)ion conductivity. The well-defined Mn(3)O(4)nanorods, strong interaction between Mn(3)O(4)and NrGO, and highly graphitic properties of Mn-NrGO result in superior reversible capacity, long cycle life, and superior rate performance of approximately 1500 mAh/g at 0.1 C after 100 cycles and >660S mAh/g at 1.0 C after 500 cycles.
