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