High electrochemical performance of nickel cobaltite@biomass carbon composite (NiCoO@BC) derived from the bark of Anacardium occidentale for supercapacitor application

Nickel cobaltite hydroxide NiCo 2 O 4 /NiOOH (NiCoO) with biomass carbon (BC) are successfully synthesized using the bark of Anacardium occidentale extract as a carbon source via an energy-saving hydrothermal process. The carbon from biomass greatly enhances the electrochemical performances of NiCoO.
