“…Despite these endeavors, various challenges persist, including sluggish reaction rates, irreversible electrochemical reactions, the formation of a solid electrolyte interface (SEI), and electrode volume expansion [106]. To address these issues, several research groups have explored the use of composite materials based on N-doped graphene and MOF(ZIF-8) as battery electrodes [48][49][50][51][52]. The literature reveals that N-G/ZIF-8based/derived composite materials not only offer improved structural stability for the electrodes, but also enhance the electrochemical kinetics by providing a host of different active sites.…”

“…By deconvoluting the XPS S 2p narrow-scan spectra of the material, the researchers confirmed the existence of the Zn-S bond in the ZIF-8@rGO/S composite, demonstrating that ZIF-8 could effectively interact with the sulfur atoms of polysulfides, immobilizing them at the Zn sites. Zhang et al investigated the challenges faced by conventional anodes in potassiumion batteries (PIBs) due to the large radius of potassium ions (K + ), leading to significant volume changes and slow reaction kinetics [51]. Such an issue ultimately leads to an inferior structural stability and weak electrochemical activity for the PIB anodes.…”

In recent years, graphene-type materials originating from metal–organic frameworks (MOFs) or integrated with MOFs have exhibited notable performances across various applications. However, a comprehensive understanding of these complex materials and their functionalities remains obscure. While some studies have reviewed graphene/MOF composites from different perspectives, due to their structural–functional intricacies, it is crucial to conduct more in-depth reviews focusing on specific sets of graphene/MOF composites designed for particular applications. In this review, we thoroughly investigate the syntheses, characteristics, and performances of N-G/MOF(ZIF-8)-based/derived materials employed in electrochemical energy conversion and storage systems. Special attention is given to realizing their fundamental functionalities. The discussions are divided into three segments based on the application of N-G/ZIF-8-based/derived materials as electrode materials for batteries, electrodes for electrochemical capacitors, and electrocatalysts. As electrodes for batteries, N-G/MOF(ZIF-8) materials can mitigate issues like an electrode volume expansion for Li-ion batteries and the ‘shuttle effect’ for Li-S batteries. As electrodes for electrochemical capacitors, these materials can considerably improve the ion transfer rate and electronic conductivity, thereby enhancing the specific capacitance while maintaining the structural stability. Also, it was observed that these materials could occasionally outperform standard platinum-based catalysts for the electrochemical oxygen reduction reaction (ORR). The reported electrochemical performances and structural parameters of these materials were carefully tabulated in uniform units and scales. Through a critical analysis of the present synthesis trends, characteristics, and functionalities of these materials, specific aspects were identified that required further exploration to fully utilize their inherent capabilities.

“…[27][28] Notably, rGO provides significant advantages in enhancing the electrode's performance, allowing for faster ion and electron transport kinetics and more active sites for electrochemical activities. [29] Moreover, the rGO can be functionalized with diverse oxygen-containing groups, allowing for tailored ion adsorption and desorption while regulating the interaction between the electrode and the electrolyte. [11] This property changes the spatial distribution of EDL near the electrode, affecting the electrode-electrolyte interface.…”

Reduced graphene oxide (rGO) has been demonstrated to effectively enhance the potassium storage performance of transition metal selenides due to its robust mechanical properties and high conductivity. However, the impact of rGO on the electrode‐electrolyte interface, a crucial factor in the electrochemical performance of potassium‐ion batteries (PIBs), requires further exploration. In this study, we synthesized a seamless architecture of rGO on FeSe/C nanocrystals (FeSe/C@rGO). Comparative analysis between FeSe/C and FeSe/C@rGO reveals that the rGO layer exhibits robust adsorption energies towards EC and DEC, inducing the formation of organic‐rich solid‐electrolyte interphase (SEI) without damage to the structural integrity. Furthermore, incorporating rGO triggers K+‐ions into the double electrode layer (EDL), markedly improving the transport of K+‐ions. As a PIB anode, FeSe/C@rGO exhibits a reversible capacity of 332 mAh g‐1 at 200 mA g‐1 after 300 cycles, along with excellent long‐term cycling stability, showcasing an ultralow decay rate of only 0.086% per cycle after 1900 cycles at 1000 mA g‐1.

MnSe and Co0.85Se embedded in nitrogen‐doped carbon nanofibers (MnSe/Co0.85Se/N‐CNFs) were synthesized by electrospinning and high‐temperature calcination, and evaluated for the first time as sodium/potassium‐ion battery anode material via constant current charge/discharge, cyclic voltammetry, electrochemical impedance spectroscopy.Ex‐situ XRD revealed the potassium storage mechanism of MnSe/Co0.85Se/N‐CNFs, indicating that its capacity was mainly provided by the conversion reaction. Compared with MnSe/N‐CNFs and Co0.85Se/N‐CNFs, the reversible capacity and cycling performance of MnSe/Co0.85Se/N‐CNFs were significantly improved due to the synergistic effect of bimetals. The MnSe/Co0.85Se/N‐CNFs electrode showed a charging capacity of 262.3 mAh g−1 after 700 cycles at 1 A g−1 in Na‐ion batteries and a discharge capacity of 183.4 mAh g−1 after 400 cycles at 0.1 A g−1 in K‐ion batteries, The results showed that binder‐free binary metal MnSe/Co0.85Se/N‐CNFs have a certain development prospect as anode for sodium/potassium‐ion batteries.
