Abstract

Micro-nanostructured Mn2O3@CNTs materials have been successfully synthesized via a carbonate precursor route: MnCO3 ellipsoids precursor were first prepared via a facile hydrothermal approach, and treated by KMnO4 and HCl solutions, then a mesoporous intermediate obtained, followed by heat-decomposition at 500 or 700 °C. After mixed with a small amount of carbon nanotubes, Mn2O3@CNTs materials were used as anodes for lithium ion batteries. The sample annealed at 700 °C exhibits a micro-nanostructured architecture which shows superior electrochemical performance, ex., 802 mA h g−1 after 200 cycles at a current density of 200 and 486 mA h g−1 after 1000 cycles at 1000 mA g−1. This long-term cycling performance depends on the micro-nanoscaled structure that mixed excellent with carbon nanotubes which powers electrolyte penetration and Li+ transport.
