Summary: This study reports a method for the fabrication of freestanding and thick supercapacitor electrodes using a one-step electrochemical deposition on carbon foam. The use of polydopamine effectively controls the stacking of polypyrrole, while the hierarchical pore structures in the carbon foam facilitate the infiltration of electrolyte. The composite electrode exhibits a capacitance of 1920 mF cm(-2) with a loading of 8.5 mg cm(-2) of the PPy/PDA coating. The assembled symmetric supercapacitor shows excellent capacitance and high energy density, with 100% capacitance retention after 10,000 charging/discharging cycles.

Summary: Transition metal nitrides (TMNs) and their composites with carbon materials show great potential for supercapacitor (SC) electrodes due to their excellent conductivity and electrochemical activity. However, achieving economically viable and environmentally friendly cycling stable TMN/carbon-based supercapacitors remains a challenge. This study successfully fabricated vanadium nitride (VN) embedded in PAM hydrogel-derived N-doped porous carbon (NPC) through an ammonia-free process. The VN/NPC composite exhibits high specific capacitance and cycling stability, and the solid-state symmetric device based on VN/NPC demonstrates excellent energy density and cycling durability.

Summary: In this study, dense carbon materials were prepared using a novel hydrogel carbonization method. The carbonization processes of sugar-PAM hydrogels were investigated, and it was found that the sugar solution was surrounded by PAM and formed hydrogels. The sugar molecules were restricted within the hydrogel via walls formed by PAM chains. The self-generated pressure of the hydrogel constrained the expansion of sugar during heat treatment, resulting in dense carbon materials with low graphitization and no porous structure.

Summary: Researchers designed a highly self-adhesive and deformable polyacrylamide-based hydrogel electrode with the inspiration of mussels. By incorporating nanofillers with confined nanospace formed by the composite of polydopamine-reduced graphene oxide and cobalt-nickel bimetal oxide and cobalt nitride, the hydrogel electrode exhibited impressive self-adhesive property and electrochemical performance. They also assembled a multifunctional all hydrogel-based supercapacitor using the same polyacrylamide hydrogel matrix for both electrodes and electrolyte, which provided a tightly connected interface, structural stability, and highly electrical stability.
