Recent progress of dimensionally designed electrode nanomaterials in aqueous electrochemical energy storage

Abstract

Uneven energy distribution in space–time has led to an increase in the demand for energy storage devices. In recent years, aqueous energy storage systems have attracted considerable attention because of their low manufacturing costs and superior safety. For next-generation energy storage systems, the cyclic stability of the electrode material and exceptional energy storage performance are necessary. This review briefly summarizes the performance of aqueous electrochemical energy storage devices based on nanodimensions, including aqueous sodium-ion batteries, aqueous aluminum-ion batteries, aqueous zinc-ion batteries, aqueous supercapacitors, and other aqueous electric energy storage systems. Furthermore, to reveal the mechanism of the energy storage performance among various electrode materials with varying dimensions, we highlight the recent significant progress of novel electrode materials based on their rational design, controlled synthesis, and corresponding energy storage performance.
