“…Powder X‐ray diffraction (XRD) patterns (Figure S1) confirm the amorphous characteristics of Co−MOP@COF, in which the characteristic diffraction peak at 4.7° can be ascribed to the (100) plane of COF, and the broad peak at around 22° for Co−MOP indicates the lack of long‐range order for the structure [40,41] . The Fourier‐transform infrared (FTIR) spectrum of the Co−MOP@COF hybrid also indicates the existence of the COF and Co−MOP components, as shown in Figure 1a.…”

Due to the adjustable structure and the broad application prospects in energy and other fields, the exploration of porous organic materials [metal‐organic polymers (MOPs), covalent organic frameworks (COFs), etc.] has attracted extensive attention. In this work, an imine‐induced metal‐organic and covalent organic coexisting framework (Co−MOP@COF) hybrid was designed based on the combination between the amino units from the organic ligands of Co−MOP and the aldehyde groups from COF. The obtained Co−MOP@COF hybrid with layer‐decorated microsphere morphology exhibited good electrochemical cycling performance (a large reversible capacity of 1020 mAh g−1 after 150 cycles at 100 mA g−1 and a reversible capacity of 396 mAh g−1 at 500 mA g−1) as the anode for Li‐ion batteries. The coexisting framework structure endowed the Co–MOP@COF hybrid with more surface area exposed in the exfoliated COF structure, which provided rapid Li‐ion diffusion, better electrolyte infiltration, and effective activation of functional groups. Therefore, the Co−MOP@COF hybrid material achieved an enhanced Li storage mechanism involving multi‐electron redox reactions, related to the CoII center and organic groups (C=C groups of benzene rings and C=N groups), and furthermore improved electrochemical performance.

“…The approximate rectangle shape of the CV curve for the Fe 2 O 3 @rGO anode in the voltage window of −1.0–0 V suggests the capacitive behavior in the charge storage process, whereas the CV curve of the Cu−Mo−S NSs cathode in the voltage window of −0.2–0.6 V demonstrates a battery‐type diffusion‐controlled behavior. The construction of HSC has been regarded as an effective strategy to broaden the voltage window of SCs due to the combination of different charge storage mechanisms between the cathode and anode [70,71] . As is well known, the HSC can achieve boosted electrochemical properties in an appropriate voltage window.…”

The construction of integrated electrodes has been considered as a sensible strategy to boost the electrochemical properties of supercapacitors, which feature improved electron and ion transfer kinetics. In this work, a facile and easy‐controlled synthetic methodology has been established to assemble hierarchical honeycomb‐like copper‐molybdenum sulfide nanosheets (Cu−Mo−S NSs) on a three‐dimensional (3D) porous nickel foam substrate as integrated cathodes for hybrid supercapacitors (HSCs). As expected, the Cu−Mo−S NSs deliver exceptional electrochemical properties including an areal capacity of 1.39 mAh cm−2 at 2 mA cm−2, a superb rate capability (0.86 mAh cm−2 at 20 mA cm−2), and especially, a prominent cycling lifespan with 95.3 % capacity retention after 10000 cycles. Moreover, the as‐obtained Cu−Mo−S NSs are used as integrated cathodes to pair with iron oxide particles encapsulated in reduced graphene oxide (Fe2O3@rGO) as anodes for assembling Cu−Mo−S NSs//Fe2O3@rGO HSCs, which can deliver superior energy density of 79.04 Wh kg−1 and exceptional cyclic stability with 94.9 % capacity retention after 10000 cycles.

“…There are many factors affecting the performance of SCs, such as electrode materials, electrolytes, separators, and assembly processes, among which the development of rich, cheap and highly electrochemically active electrode materials is the key to enhancing the performance of current SCs [180] . MOFs, as a porous network material, have microstructural tunability, long‐range orderliness and controllable porosity, which enable them to be one of the best candidate electrode materials for SCs [181–188] . It should be highlighted, nevertheless, that even the majority of pristine MOFs have inherent flaws such as poor electrical conductivity, low mechanical strength and low electrochemical stability.…”

Metal‐organic frameworks (MOFs) have been important electrochemical energy storage (EES) materials because of their rich species, large specific surface area, high porosity and rich active sites. Nevertheless, the poor conductivity, low mechanical and electrochemical stability of pristine MOFs have hindered their further applications. Although single component MOF derivatives have higher conductivity, self‐aggregation often occurs during preparation. Composite design can overcome the shortcomings of MOFs and derivatives and create synergistic effects, resulting in improved electrochemical properties for EES. In this review, recent applications of MOF composites and derivatives as electrodes in different types of batteries and supercapacitors are critically discussed. The advantages, challenges, and future perspectives of MOF composites and derivatives have been given. This review may guide the development of high‐performance MOF composites and derivatives in the field of EES.
