| Abstract: | MnO nanospheres encapsulated in carbon (MnO/C) composites were synthesized through a one-step solid state reaction between potassium permanganate and salicylic acid at 700 °C, which could be transformed into MnO2 nanorods after being annealed in ambient atmosphere. Their formation mechanisms and electrochemical performances as anodes in Li-ion batteries (LIBs) were investigated. The first discharge capacity of MnO/C composites was 585.9 mA h g−1, while that of MnO2 was 1269 mA h g−1, indicating their potential applications in LIBs. |
