Derivatives of coordination compounds for rechargeable batteries

Abstract

Rechargeable batteries are promising electrochemical energy storage devices that play a critical role in portable electronics, hybrid/pure electric vehicles, and smart grids. To achieve improved performance, considerable efforts have been focused on the investigation of new electrode materials. In recent years, coordination compound-derived materials, particularly including metal–organic framework (MOF) derivatives and Prussian blue (PB) derivatives, have received enormous attention as electrode materials of rechargeable batteries because of their nanoporous structure and hierarchical nanostructure. The features of coordination compound derivatives not only can facilitate the transport of the electrolyte, but also shorten the diffusion path of metal ions in the solid-state phase. In this study, we present a review on the recent developments in the application of coordination compound-derived materials (mainly including MOF- and PB-derivatives) in various rechargeable batteries, such as lithium-ion batteries, sodium-ion batteries, lithium–sulfur batteries, lithium–oxygen batteries, and zinc–air batteries. The synthesis, morphological characteristics, and electrochemical properties of the coordination compound derivatives are summarized. Furthermore, future outlooks regarding these developments are proposed.
