Low cost, non-toxic nanomaterials and their controllable synthesis are highly demanded in the field of supercapacitors. In this work, nanoneedle and nanosheet-like porous NiCo2O4 architectures were directly fabricated on graphitic carbon nitride (g-C3N4), indicating structure dependence on their capacitive performances. Electrochemical performances show that nanoneedle-assembled NiCo2O4/g-C3N4 exhibits...
Hollow nanostructured anode materials lie at the heart of research relating to Li-ion batteries, which require high capacity, high rate capability, and high safety. The higher capacity and higher rate capability for hollow nanostructured anode materials than that for the bulk counterparts can be attributed to their higher surface area, shorter path length for Li+ transport, and more freedom for volume...
