Ultrahigh energy density supercapacitors through a double hybrid strategy
Abstract
Herein, we are presenting all-solid-state symmetric supercapacitors (ASSSCs) with an innovative double hybrid strategy, where a hybrid material based on reduced graphene oxide (rGO) anchored with phoshotungstic acid, rGO-H<sub>3</sub>PW<sub>12</sub>O<sub>40</sub>) is combined with hybrid electrolyte (hydroquinone-doped gel electrolyte). Initially, a hybrid electrode is fabricated by decorating H<sub>3</sub>PW<sub>12</sub>O<sub>40</sub> nanodots onto the surface rGO (rGO-PW<sub>12</sub>). Next, a symmetric cell based on rGO-PW<sub>12</sub> electrodes was assembled with PVA-H<sub>2</sub>SO<sub>4</sub> polymer gel-electrolyte. Interestingly, rGO-PW<sub>12</sub> symmetric cell revealed a substantial enhancement in the cell performance as compared to parent rGO systems. It featured a widened potential range of 1.6 V, thereby providing 1.05 mWh/cm<sup>3</sup> energy density. The electrochemical performance of rGO-PW<sub>12</sub> cell was further advanced by introducing redox-active (hydroquinone) species in to the PVA-H<sub>2</sub>SO<sub>4</sub> gel-electrolyte. Indeed, the performance of rGO-PW<sub>12</sub> cell was surprisingly improved with an ultra-high energy density of 2.38 mWh/cm<sup>3</sup> (more than two-fold).
