摘要: MnO/C core-shell nanowires with varying carbon shell thickness were synthesized via calcining resorcinol-formaldehyde resin(RF) different amounts of hydrothermally MnO2 nanowires. The relationship between the and anode performance materials was discussed. With a suitable thickness(6.8 nm), exhibit better cycling rate than those smaller or larger thickness. TEM results show that after 50 cycles, structure this can be retained, which leads to superior performance. This contribution provides significant guiding model for optimizing electrochemical by controlling shells.
