Abstract
Mn6.87(OH)3(VO?)3.6(V?O?)0.2 microtubes were successfully synthesized by a simple and facile hydrothermal method without using any surfactants or additives. The reaction conditions influencing the structures and morphologies of the products, such as reaction time, reaction temperature, and pH value, were systematically investigated. An Ostwald ripening-dissolution-recrystallization process was proposed to elucidate the formation of the tube-like microstructure. Electrochemical measurements revealed that the as-prepared Mn6.87(OH)3(VO?)3.6(V?O?)0.2 microtubes exhibited high specific capacity, high coulombic efficiency, and good cycling stability, indicating a promising anode candidate for application in lithi
