Chemical power source based on layered double hydroxides

Abstract

Layered double hydroxides (LDHs) have been widely investigated in the past years because of their unique physicochemical properties and promising applications in chemical power sources. In this article, we review the current work on applications in areas such as supercapacitors, fuel cells, metal-air batteries, Li-ion batteries based on various LDH materials, such as LDH powder, LDH nanosheet, LDH film, or their composites, and offer some perspectives for the future application and development direction of LDHs.
