Mn₃O₄/CNTs composite as anode materials for lithium-ion batteries

Abstract

Transition metal oxides especially manganese oxides are being intensively studied as candidate anode materials for next generation lithium ion batteries in high efficiency energy storage applications. In this paper, Mn3O4 /CNTs composite is prepared via a facile one-step solvothermal method. The results of XRD and SEM showed that Mn3O4 uniformly coated on the surface of CNTs. It could deliver a reversible charge capacity of 809.9 mA h g -1 at the current density of 40 mA g -1 , and the specific discharge capacity slightly increased from 644.2 mA h g -1 to 796.1 mA h g -1 after 50 cycles at a current density of 160 mA g -1 demonstrating excellent cycling stability.
