Azure C-decorated N-doped graphene aerogel/AC−NGA

Azure C-decorated N-doped graphene aerogel/AC−NGA/AC-decorated N-doped graphene aerogel/Azure C−NGA from ruixi.AC-NGA has excellent charge storage performance under universal pH conditions (gravitational capacitance up to 591Fg-1 at a current density of 1.0A g-1 and an ultra-high voltage window of 2.3V). The capacitance contribution to charge storage is 91.7%, which exceeds or is comparable to the best known pseudocapacitors. In addition, the symmetric AC-NGA//AC-NGA devices achieve high energy and power density (15.2-60.2 Wh kg-1, 650-23,000 W kg-1) and have excellent performance in acidic, neutral and alkaline aqueous solutions. Excellent cycling stability. This work provides a cost-effective strategy to combine redox dye molecules with heteroatom-doped graphene aerogels to construct green, efficient, pH-universal aqueous supercapacitors.
