Developing an anode material with long‐cycling stability and excellent rate performance is critical for enhancing the Na+ storage performance. Herein, an effective method is applied to prepare the carbon‐coated CoP embedded into graphene aerogel (CoP@C/GA) as an anode material for sodium‐ion batteries (SIBs). GA network with large specific surface area and cross‐linked pores provides sites for loading CoP@C, which reduces the agglomeration of CoP@C and accelerates the electron and ion transfer kinetics. The CoP@C particles with abundant pores help to buffer the volume change of CoP during the Na+ insertion/extraction. Meanwhile, CoP crystal particles break down and become smaller during the long‐cycling, resulting in an increase of contact area with the electrolyte. Therefore, the CoP@C/GA anode exhibits ultralong cycling stability (172.8 mAh g−1 at 2000 mA g−1 over 4000 cycles with capacity retention ratio of 115.2 %), and superior rate performance (gradually increasing from 50 mA g−1 to 2000 mA g−1 and returning to 50 mA g−1, the capacity retention rate is 94.1 %). Furthermore, the storage mechanism of CoP@C/GA is mainly controlled by pseudocapacitive behavior, which leads to a rapid Na+ insertion/extraction and excellent rate performance. The prominent cycling stability of CoP@C/GA provides a bright prospect in SIB.

Recently, sodium-ion batteries (SIBs) are extensively explored and are regarded as one of the most promising alternatives to lithium-ion batteries for electrochemical energy conversion and storage, owing to the abundant raw material resources, low cost, and similar electrochemical behavior of elemental sodium compared to lithium. Metal-organic frameworks (MOFs) have attracted enormous attention due to their high surface areas, tunable structures, and diverse applications in drug delivery, gas storage, and catalysis. Recently, there has been an escalating interest in exploiting MOF-derived materials as anodes for sodium energy storage due to their fast mass transport resulting from their highly porous structures and relatively simple preparation methods originating from in situ thermal treatment processes. In this Review, the recent progress of the sodium-ion storage performances of MOF-derived materials, including MOF-derived porous carbons, metal oxides, metal oxide/carbon nanocomposites, and other materials (e.g., metal phosphides, metal sulfides, and metal selenides), as SIB anodes is systematically and completely presented and discussed. Moreover, the current challenges and perspectives of MOF-derived materials in electrochemical energy storage are discussed.

Due to their high theoretical capacities, metal sulfides have been considered as promising electrode materials for lithium‐ion batteries (LIBs). Heavy‐duty applications of metal sulfides for LIBs, however, are still restricted by the unavoidable volume change, resulting in poor rate capability and cycling stability. In this work, a Ni−Co‐ZIF derived Ni0.2Co0.8S hollow nanocage@reduced graphene oxide (Ni0.2Co0.8S@rGO) composite was fabricated through facile self‐assembly followed by freeze‐drying. The highly porous architecture of Ni0.2Co0.8S hollow nanocages wrapped by flexible reduced graphene oxide (rGO) is shown to not only validly inhibit the huge volume expansion during repeated charge/discharge cycling, but also accelerate lithium‐ion and electron transport through the 3D rGO network. The as‐obtained Ni0.2Co0.8S@rGO exhibits excellent electrochemical performance with a high specific capacity of 1585 mA h g−1 after 250 cycles at a current density of 1 A g−1. It is shown that the increasing reversible capacity during cycling can be attributed to the electrochemical activation of porous Ni0.2Co0.8S‐2.5@rGO, the pseudocapacitive behavior, and the highly reversible formation/decomposition of the solid electrolyte interface layer during lithiation/de‐lithiation. The sulfidation and reduction syntheses were operated at a relative low temperature of 90 °C, which is beneficial to inherit the unique morphology of precursor.
