Multiscale nanomaterials for electrochemical energy storage and conversion

High-performance electrochemical energy storage and conversion devices (EESCDs) are highly desirable for meeting sustainable development of human society. It is the assiduous goal to develop advanced EESCDs with large power/energy density and high conversion efficiency. This special issue presents a collection of the most recent advances in EESCDs including lithium ion batteries, supercapacitors, alkali ion batteries, alkaline batteries, and photo-electrochemical devices. The recent development on controllable synthesis of multiscale nanomaterials and nanostructures of EESCDs is also proposed. The electrochemical performances of different types of multiscale nanomaterials and composites are presented. Moreover, design rules and corresponding merits/demerits are discussed and future research trend is analyzed.
