Surface Science and Engineering for Electrochemical Materials
In electrochemical energy storage systems, the reversible storage capacity of battery materials often degrades due to parasitic reactions at the electrode–electrolyte interface, transitional metal dissolution, and metallic dendrite growth at the surface. Surface engineering techniques offer the opportunity to modify the composition and structure of a surface, thereby enabling control over chemical reactions occurring at the surface and manipulating chemical interactions at the solid–solid or solid–liquid interface. These modifications can help stabilize the surface of electrode materials and prevent unwanted reactions with electrolytes without changing the original properties of the bulk structure. This allows for achieving full theoretical capacity and maximizing battery material capacity retention with minimal overpotentials. In the past decade, our teams have been working on developing a variety of surface engineering techniques. These include applying atomic and molecular layer deposition (ALD and MLD), templating, doping, and coating via wet-chemical processes to stabilize the surfaces of electrode materials. The aim is to mitigate parasitic side-reactions without impeding charge transfer kinetics, suppress dendrite growth, and ultimately improve the electrode performance.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
