Ti-doped Mn3O4 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, Ti-doped Mn3O4 composite is prepared via a facile one-step solvothermal method. The results of XRD and SEM showed that the product is cotton-shaped mixed up with the Mn3O4 particles. It could deliver a reversible charge capacity of 557.8 mA h g−1 at the current density of 35.5 mA g−1, and thex specific discharge capacity is still have 478.1 mA h g−1 after 40 cycles at a current density of 35.5 mA g−1 demonstrating good cycling stability.
