Sustainable one-pot aqueous route to hierarchical carbon–MoO2 electrodes for Li-ion batteries

摘要: A route towards carbon–MoO2 core–shell spheres has been developed, through hydrothermal decomposition of ascorbic acid combined with precipitation MoO2 nanoparticles. In this one-pot and green process, carbon originating from act as seeds for the in situ deposition a corona made 30 nm molybdenum dioxide particles. The as-obtained hierarchical nanostructured exhibit an ideal combination electrical conductivity lithium reactivity Li-ion battery electrodes. This nanocomposite offers opportunity to master collector-active material active material–electrolyte interfaces. Direct transfer “from beaker battery” without any additives nor thermal treatment yields storage capacity values ca. 600 mA h·g−1 at C/5 rate excellent stability that challenges state-of-the-art oxide-based batteries.
