At present worldwide conditions of energy crises, efficient energy conversion and storage systems are most needed. Accordingly, HSC cells are proposed that comprise one EDLC-type and other battery-type electrodes. Thus, HSC can deliver a high power, short charging-discharging periods, ED comparable to the batteries, and long cycle life. In this regard, present work is focused on improving electrode performance of Co-Cr-LDH by hybridizing it with various nanostructures to enable high surface area, accessible gallery space, and improved conductivity. The Co-Cr-LDH-based nanohybrids were...
