Abstract:The nanosize effect in nanostructured electrode materials is significant for boosting rate performance; however, it brings about low capacity, low Coulombic efficiency, and poor stability. In this work, 2D atomically thin (001)-oriented single-crystalline LCO (SC-LCO) nanosheets with longer Li + intercalation distance and a surface dominated with (001) planes are constructed to regulate the nanosize effect. The SC-LCO not only owns large plateau region capacity even at high rate (194 mAh g −1 at 1C and 111 mAh… Show more
Metal-nitrogen-carbon has attracted great research interests for sodium storage. However, the limited and unstable M-Nx active sites result in poor rate performance and inferior cycle life. Herein, CoFe nanoalloy clusters...
Layered TiO2(B) displays intercalation pseudocapacitance for rapid Na+ storage, and the capacities and capacitor-like behaviors are independent of the surface area and morphology.
