“…As for the N 1s XPS spectrum in Figure 4c, three peaks at 399.0 eV, 400.8 eV, and 402.6 eV were assigned to pyridinic N, pyrrolic N, and graphitic N, respectively [43]. Importantly, due to the existing of the conjugation between the lone pair of electrons of the N atom and large π-bonds of the reduced graphene oxide lattice, the nitrogen doped in the reduced graphene oxide can enhance the electronic conductivity and provide more reactive sites [23,27,[44][45][46][47]. The high-resolution Ni 2p XPS spectra of NiS 1−x Se x @N-rGO and NiS@N-rGO composites can be observed in Figure 4d.…”

Nickel sulfides are regarded as one of the promising anode materials for sodium-ion batteries (SIBs), but the sluggish electrodes kinetics and rapid capacity decay, caused by their intrinsic low electrical conductivity and high bulk expansion, greatly limit their practical application. To overcome these obstacles, nano-sized, selenium-doped, nickel sulfide particles, anchored on nitrogen-doped reduced graphene oxide composites (NiS1−xSex@N–rGO), are rationally synthesized. The broad Na+ diffusion channels, resulting from Se doping, as well as the short Na+ transferring path, attributed from nano-size scale of NiS1−xSex particles, endow NiS1−xSex@N–rGO composites with ultrafast storage kinetics. Moreover, strong coupled effect between the NiS1−xSex and N–rGO is beneficial to the uniform dispersion of NiS1−xSex nanoparticles, improving electrical conductivity and suppressing the volume variation in charge/discharge process. Furthermore, the cut-off discharge voltage is modulated to realize the smaller volume change during cycle process. As a result, the fabricated anode of SIBs based on NiS1−xSex@N–rGO composites exhibits a high specific capacity of 300 mAh g−1, at the current density of 1 A g−1, after 1000 cycles with almost no capacity degradation.

“…Owing to their large pore volumes and adjustable physical properties, it is suggested that the electrochemical performances of these ZIF-derived carbons as Li-metal storage hosts can be maximized by controlling these properties. Moreover, as reported [ 22 ], by controlling the synthesis of bimetallic ZIF-derived carbon, Co nanoparticle embedded highly mesoporous carbon is proposed as a new innovative Li-metal host anode. This material shows enhanced Li affinity and superior electrochemical performance.…”

The development of lithium (Li)-metal anode is high priority research to initiate next-generation Li batteries. Applying Li-metal in practical applications as anode still has many hurdles to clear away, such as low Coulombic efficiency and capacity degradation by the continuous formation of dead Li. We demonstrate that cobalt (Co) nanoparticle incorporation in a porous carbon host anode can play a critical role in the formation of a thick lithium fluoride dominated solid-electrolyte interphase in ether-based electrolyte. As a result, the host anode containing Co nanoparticles shows excellent electrochemical performance with high Li-metal reversible capacity and even stable long-term cyclability with no dead Li formation.

“…The generated Co nanoparticles and doped N atoms supply nucleation sites for Li deposition, and the large surface area originating from the porous carbon skeletons reduce the local current density for Li deposition. [ 216–220 ] For instance, Fan et al. prepared a Co nanoparticle/N‐doped graphene‐modified Li metal anode via the one‐step carbonization of a ZIF‐67 precursor.…”

The commercialization of high‐energy‐density alkali metal (Li, Na, and K)–chalcogen (S, Se, and Te) batteries (AMCBs) has been primarily hindered by the volume expansion of chalcogen cathodes during repeated charging/discharging cycles, the shuttling effect of intermediates in the electrolytes, and unstable alkali metal anodes. Owing to their unique structural and physicochemical characteristics, including high specific surface areas, self‐doped N atoms, open pore structure, versatile compositions, and favorable chemical stability, zeolitic imidazolate frameworks (ZIFs) and their derivatives have been widely used in different battery components, such as cathodes, anodes, separators, and interlayers, to resolve these issues simultaneously. This review discusses recent advances in ZIFs and their derivatives for cathode construction, anode protection, and interlayer/separator design in AMCBs. The processing methods, structure and morphology engineering, composition tuning, and electrochemical performance of various ZIFs and their derivatives are systematically examined. More importantly, the remaining challenges and future research directions are summarized and discussed. This review is expected to offer new approaches for the rational design of ZIFs and their derivatives for emerging energy storage devices.
