Ternary metal layered hydroxides: As promising electrode materials for supercapacitors

Ternary layered double hydroxides as electrode materials for supercapacitors have attracted special attention in recent years. Although there have been many excellent studies on the synthesis, composition, structure and morphology on the ternary layered double hydroxides electrode materials, none systemically summarize the effects of the support and composition on the electrochemical performance in the supercapacitor. In this review, we discuss the recent progress of synthesis method, composite design and composition design of ternary double hydroxides in the field of the supercapacitor. Finally, the possible development directions and opportunities of ternary double hydroxides are also put forward.
