Abstract Aqueous symmetric carbon‐based supercapacitors (CSCs) are always the research focus for energy storage devices because of virtue low cost, inherent safety, and encouraging electrochemical stability. As is well‐known, so far most aqueous CSCs subjected to densities. Here, a supercapacitor comprising electrodes from biomass‐derived activated carbon alkaline–acidic electrolyte reported. This CSC demonstrates exceptional performance with high stable working voltage 2 V attractive...
