Transition-metal phosphates/phosphides, as an emerging kind of prominent electroactive material, have drawn extensive attention in the fields of energy conversion and storage owing to their high electrical conductivity and metal-like properties. Herein, we report the preparation of hierarchical Ni–Co–P/PO x /C nanosheets in a controllable manner using nickel–cobalt metal–organic framework (NiCo-MOF) as the precursor, followed by a low-temperature phosphating method. Electrochemical studies show that the Ni–Co–P/PO x /C nanosheets exhibit good reversible capacity and excellent rate capability and possess capacities of 583 and 365.7 C g–1 at 1 and 30 A g–1, respectively. Furthermore, a two-electrode device assembled by Ni–Co–P/PO x /C and reduced graphene oxide shows a peak energy density of 37.59 Wh kg–1 at a power density of 800 W kg–1 and a stable capacitive performance. These results indicate that the obtained bimetallic Ni–Co–P/C is a promising anode material for capacitive energy storage devices.

Highly conductive and surface area complex hierarchical 3D core@shell nanostructures made of multi‐metallic multi‐valence sulfides are being specially designed as electrode materials of high performance and high power supercapacitors. In fact, bimetallic and trimetallic sulfides have outstanding redox properties as compared with the corresponding single‐phase sulfide based materials, and much higher electrical conductivity than the analogue oxide materials, being excellent materials for the design of core@shell structures with exceptional charge capacity, power, and energy performance. For this purpose, the core material should exhibit high charge diffusion rates and large specific capacitance, while the shell should improve the surface area by promoting a greater accessibility to the electroactive sites thus maximizing the charge capacity and conductivity. In this context, a rational design of nanostructured materials encompassing advanced 2D materials (such as graphene, MXene, black phosphorus, transition metal hydroxides, etc.), as well as carbon materials such as CNTs and carbon cloth, seems to be a very promising strategy to realize flexible enough electrode materials for the development of wearable devices, self‐charged energy storage devices and microsupercapacitors. In all cases, multi‐metallic sulfide‐based core@shell materials play a key role as electroactive materials for realization of high performance, portable and flexible energy storage devices paving the way to a more advanced and sustainable society.
