Carbon and Transition-Metal Oxide Electrodes for Supercapacitors and Energy Storage
This community develops electrode materials for supercapacitors and related electrochemical energy storage devices, focusing on carbon-based structures and transition-metal oxides to achieve high power and energy density.
The research centers on synthesizing porous carbon, graphene oxide, reduced graphene, and activated carbon, often combined with nickel, cobalt, and manganese oxides or layered double hydroxides. A significant portion of the work involves asymmetric and hybrid supercapacitor architectures, where these materials are engineered for enhanced electrochemical performance. MXenes also appear frequently as a key material class. The primary application is energy storage, with a secondary focus on capacitive deionization and hydrogen evolution reactions. The work emphasizes electrode engineering, composite formation, and the optimization of charge storage mechanisms to improve device efficiency and durability.
The community is most prominent in nickel research, representing 5.9% of all nickel studies, and in cobalt research, accounting for 4.8% of that element's literature. It also constitutes 4.7% of carbon research. Nickel contributes the highest number of papers to this group, with 2,285 entries, while cobalt follows with 2,097.
There are 20,470 papers in this community, with the highest publication volume in the Journal of Energy Storage, Electrochimica Acta, and the Journal of Power Sources.
Recent work continues to focus on MXene terminations and synthesis, the development of "supercapattery" devices that combine battery and supercapacitor functionalities, and the refinement of reduced graphene oxide electrodes. Studies also explore double-transition metal MXenes for energy conversion and the use of tailored nanostructures like barium zirconate in asymmetric supercapacitors.
