Hybridizing <scp> ZnCo <sub>2</sub> O <sub>4</sub> </scp> ‐decorated <scp>MWCNTs</scp> : Electrode to symmetric solid‐state supercapacitor configuration
Abstract Meticulously crafted architectures of hybrid materials through logical and rational design play an essential role in amplifying the performance of supercapacitors. Herein, high‐density sequential growth controlled ZnCo 2 O 4 nanoparticles decorated on ‘dip and dry’ coated MWCNTs is proposed as a hybrid supercapacitive electrode to design a solid‐state configured symmetric supercapacitor (SSS) device. Synthesized MWCNT/ZnCo 2 O 4 has been utilized as an electrode at a scan rate of 5 mV s −1 and a specific capacitance of 1081 F g −1 is attained with 72% capacitive retention after 10,000 CV cycles. Furthermore, the MWCNTs/ZnCo 2 O 4 device showcased a volumetric capacitance of 157 mF cm −3 , a volumetric energy density of 21.80 mW h cm −3 , and a balancing volumetric power density of 1509.79 mW cm −3 at a current density of 0.92 mA cm −3 .
