Summary: Carbon/manganese oxide hybrid materials have attracted extensive attention as lithium-ion battery anode materials due to their abundant resources and simple preparation. However, their poor rate performance, weak cycle stability, and relatively high cost hinder their further development. In this study, a novel carbon/manganese oxide hybrid material was fabricated using low-cost carbonized bamboo leaves and manganese nitrate. The addition of MnSiO3 component in the hybrid material improved its intrinsic conductivity and Li+ diffusion ability, resulting in significantly improved rate capability and cycle performance compared to the hybrid material without MnSiO3. The excellent electrochemical performance of the hybrid material enables its application in lithium-ion full batteries with considerable energy storage performance.
