Front Cover: Amorphous and Crystalline Vanadium Orthophosphate and Oxidized Multiwalled Carbon Nanotube Composites as Anode Materials in Sodium‐Ion Batteries (ChemElectroChem 16/2022)

Abstract

The Front Cover schematically illustrates the structure of the anodic electroactive composite of vanadium phosphate and multiwalled carbon nanotubes for a sodium battery. The complex processes in this system involve electron transfer at the electrode surface/electroactive material interphase, electron and ion transfer within the electroactive material, double layer charging, and the vanadium phosphate reduction process. The structure of vanadium phosphate and multiwalled carbon nanotubes composite facilitates the efficient transport of both ions and electrons. Such a sodium battery anode exhibits promising capacitance properties, good rate performance and long lifetime. The capacity performance of this composite is even higher compared to the capacity properties of carbon materials such as ford carbon, which is commonly used in sodium ion batteries.
