Abstract
- Nanohybrid materials comprising polyoxometalates (POMs) and nanocarbons have attracted considerable attention as electrode‐active materials for rechargeable lithium‐ion batteries (LIBs). These materials exhibit multi‐electron redox reactions, resulting in an improved battery capacity. This study focuses on carbon nanohorns (CNHs) as a nanocarbon material and evaluates the battery performance using POM/CNH hybrids as cathode‐active materials. X‐ray absorption fine structural analysis was performed to investigate the reaction mechanism of these hybrids. POM/oxidized CNH (CNHox) hybrid materials maintain high capacities at high current densities as the high surface area availability of CNHox leads to high electrical double‐layer capacitances. These findings show an improved performance of the as‐developed material when compared with those reported in previous papers and can contribute toward an improved design of cathode‐active materials for high‐performance supercapacitors.
