Abstract

Energy density and mechanical strength are crucial for practical usage of flexible supercapacitors. Herein, we demonstrate a flexible supercapacitor using Ni(OH)₂/CNTs hierarchical spheres with high specific capacity (854 C g⁻¹) and tough PBI-KOH solid polymer electrolyte. The integrated device shows high specific energy (50.6 W h kg⁻¹) and good flexibility under folding tests.
