摘要：

This work presents a prototype solid-state symmetric supercapacitor (SSS) using cobalt iron phosphate-anchored multiwalled carbon nanotubes (MWCNT/Co3Fe4(PO4)6) with a polyvinyl alcohol-potassium hydroxide (PVAKOH) gel electrolyte. This advanced structure overcomes issues of the liquid electrolytes like leakage and degradation, enhancing mechanical resilience and longevity. The device exhibited a specific capacitance of 68.6 F g-1, with energy and power densities of 21.4 Wh kg-1 and 2147.8 W kg-1 at 1 mA cm-2. Notably, the device also retained 91 % capacitance over 2000 cycles, demonstrating superior electrochemical properties, mechanical adaptability, and potential for next-generation portable energy storage technologies.
