Abstract

Carbon materials decomposed by low temperature have a higher surface area and contain micro-holes and thus have a larger lithium storage space. In this study, the natural bamboo carbon powders were used as the experimental materials to process the hydrothermal method with the post-treatment. The results show that Fe3O4 thin films are formed on the surface of carbon particles. After charge-discharge testing, it was found that the powders not only increased the capacity, but also improved the irreversibility. With increasing the concentration (0.05∼0.25 M), the coating particles became coarse and the thickness of Fe3O4 nano thin films increased. Notably, the C-0.05Fe powder had a better charge-discharge cyclability.
