High‐Performance Supercapacitors Based on Hierarchically Porous Graphite Particles

Abstract: Hierarchically porous graphite particles are synthesized using a continuous, scalable aerosol approach. The unique porous graphite architecture provides the particles with high surface area, fast ion transportation, and good electronic conductivity, which endows the resulting supercapacitors with high energy and power densities. This work provides a new material platform for high‐performance supercapacitors with high packing density, and is adaptable to battery electrodes, fuel‐cell catalyst supports, and othe… Show more

“…As the scan rate increases, CV curves show the same shape while the response current increases relatively. The redox peaks in the CV curves exhibit good mirror images with respect to the zero-the current line, revealing facile diffusion/transport of ions and good adsorption behavior [28,29]. These results indicate that the composite possesses a good rate performance for supercapacitors.…”

“…The Ragone plot generated using AN electrolyte in comparison to other best performing materials is shown in Figure 11. The plot shows that the energy/power densities obtained at 1T-MoS 2 / graphene composite are much higher than that obtained at carbon-based electrodes [58][59][60] and slightly higher than those reported for chemically exfoliated 1T-MoS 2 electrodes (Figure 11). 7 This demonstrates that the 1T-MoS 2 / graphene composite are attractive electrode for portable supercapacitor devices.…”

“…Recently, the solid-state pyrolysis route, which involves the carbonization of carbon precursors containing transition-metal (e.g., Fe, Co, and Ni) graphitization catalysts, has attracted considerable attention for its advantages of easy handling, medium temperatures, and high yields. [15,[19][20][21][22] In previous studies we had developed an effective strategy for the synthesis of highly crystalline GCNs in high yields by a solid-state pyrolysis route using polyacrylic weak-base anion-exchange resin (PAWBA) and K 3 [Fe(CN) 6 ] as the carbon source and catalyst precursor, respectively. [23] Shen and co-workers have subsequently used a similar method for the preparation of graphitic carbon.…”
