Topological Materials and Topologically Engineered Materials: Properties, Synthesis, and Applications for Energy Conversion and Storage

Topological materials have attracted intense research interest due to their nontrivial topology of band structures and their promise in applications ranging from low-power electronics to high-performance optoelectronic devices. This review provides a summary of various energy-related topological materials and topologically engineered materials that have been developed thus far and explores the unique nontrivial topological properties and topological design toward their potential application in energy conversion and storage, such as solar cells, photocatalytic and photoelectronic devices, lithium-ion batteries, and hydrogen storage. In addition, advances and critically associated issues and challenges will be discussed to stimulate broader interests in developing topological energy materials toward improvement of their applications in energy fields.
