Abstract
Background: Graphene and its derivatives have been widely used in modern electrochemical- related technologies due to their versatile structure, tunable conductivity, and large specific surface area. However, there is a need to provide the latest global literature overview in this field. Methods: In this study, we reported a literature overview of current developments in the applications of graphene in energy conversion and storage by electrochemistry. In this overview, 1285 pieces of literature were retrieved and analyzed based on the web of science core database using bibliometric tools. Results: The major contributing countries are China and the United States. The most widespread fields are the development of novel nanomaterials and catalysts and approaches to improve the electrocatalytic performance of batteries and supercapacitors. The hotspots of current research include sodium-ion batteries, lithium-sulfur batteries, sulfur-doped electrodes, and the study of high-efficiency electrocatalysts for oxygen and evolution reactions. Conclusion: With the continuous development in this field, scientists are committed to continuously improving the performance of energy equipment. The applications of graphene-based materials for electrochemical energy conversion and storage are briefly summarized. The challenges and prospects for future research in this field are also discussed.
