Although it exhibits excellent mechanical performance, the capacitive performances (especially its rate capability) are still unsatisfactory. By using KMnO<sub>4</sub>, we demonstrate a smart etching and catalytic process to form highly graphitized and etched nitrogen-doped carbon foam (ENCF) with an exfoliated carbon-shell architecture. These compositional and structural features endow the ENCF electrodes with excellent electron conductivity as well as more ion-accessible electrochemical active sites. Significantly, all-solid-state symmetric supercapacitor devices based on the ENCF electrodes exhibit enhanced specific capacitance and marked high-rate capability. Furthermore, the integrated device has no significant capacity loss under 60% compressive strain. 2017-04-17 00:00:00 nitrogen-doped carbon foam capacity loss KMnO 4 Excellent Rate Capability ENCF electrodes ion-accessible electrochemical electron conductivity electrode configuration exfoliated carbon-shell architecture Catalytic Process Freestanding rate capability supercapacitor devices ENCF electrodes exhibit Compressible Nitrogen-Doped Carbon Foam Electrode capacitive performances Smart Etching
