High volumetric capacitance electrode materials are highly desirable for miniaturized and portable capacitive storage devices. Herein, a spatially confined strategy to prepare 0D-in-2D pillared lamellar hybrid comprising vanadium nitride nanodots intercalated carbon nanosheets (VNNDs/CNSs) is proposed for promising capacitive material with high volumetric capacitance. The VNNDs/CNSs shows an ultrahigh...
Lithium-sulfur (Li-S) battery is one of the most promising energy storage systems due to its large energy density of 2560Whkg−1. However, severe shuttle effect of polysulfide intermediates, poor conductivity of S and large volume change during cycling cause fast capacity fading and poor cycle performance. Herein, we demonstrate S nanodots impregnated microporous carbon encapsulated conductive mesoporous...
