Atomically dispersed metal active centers as a chemically tunable platform for energy storage devices

Abstract

Electrochemical energy storage devices play an indispensable role in the exploitation of renewable, clean and friendly resources. The most preferred route is to use the energy directly. However, the efficiency of energy conversion and storage is dependent on the activity of electrode catalyst materials. At present, most of the catalysts materials have been nagged by shortcomings, such as low utilization, low activity, which cannot meet the ever-growing demands. Thus, it is more and more important to develop a catalyst with high efficiency and improve the coulombic efficiency of electrochemical energy storage devices. With unique electronic and structural features, atomically dispersed (AD) metal active centers exhibits the maximizing utilization, abundant active centers density, and ultra-high electrochemical activity. Especially, the AD metal catalysis has shown excellent performance in electrocatalytic energy conversion, it has also become a new star in other aspects. The present review summarizes the catalytic activity and mechanism of the recent progress in AD metal active centers as a chemically tunable platform for energy storage devices. Furthermore, the current challenges and perspectives of the AD metal research area are discussed. We sincerely expect that this review can provide some inspiration for the future of AD catalysts in energy storage, and actively promote the development of this emerging research area field.
