“…The prepared carbon nanorods and graphene nanoribbons exhibited excellent performances for supercapacitors. [17,[50][51][52][53][54][55] Presently, graphite can be utilized as a typical anode because of its low cost and efficient cycling performance. [48] Furthermore, they also fabricated high surface area (5500 m 2 g −1 ) NPCs by the direct calcination of Al-based porous coordination polymers (Al-PCP, (Al(OH)(1,4-NDC)·2H 2 O) under inert atmosphere.…”

batteries, sodium-selenium (Na-Se) batteries, Li-tellurium (Li-Te) batteries, and Na-S batteries) have their own distinctive applications due to their various characteristics. To explore new materials with high performance, large studies have been devoted to the development of nextgeneration batteries.Porous carbon (PC) materials possess many unique properties due to their large surface areas, high conductivity, large pore volumes, high thermal stability, and surface functionalities, [22][23][24] leading to their wide use in energy storage and conversion. Traditionally, PC can be obtained via various methods, such as the direct heat treatment of organic precursors, hard template or nanocast methods, and soft template methods. However, the production of PC from these methods cannot be scaled-up because of certain barriers (disordered structure with wide size distributions, complicated processes, etc.). [23,25,26] Metal-organic frameworks (MOFs) have drawn wide research interest as a novel class of porous materials that are crystalline materials consisting of metal ions and organic ligands. [4,21,[27][28][29][30][31] Since the report on the MOF-templated synthesis of PC in 2008, [32] a large number of studies have been reported on the use of MOFs as suitable precursors/templates for carbon synthesis. [22,26,[33][34][35] At present, a large number of studies indicate that zeolitic imidazolate framework-8 (ZIF-8), MOF-5, MIL-125 (Ti) (MIL = Materials of Institute Lavoisier), and ZIF-67 with excellent thermal stability and unique porous structures are the more commonly used MOF precursors (Scheme 1). [3,36,37] All of them, ZIF-8, possessing nitrogen-containing ligands, has high porosity and thermal stability. [38][39][40] MOF-5 possesses excellent thermal stability, high porosity, and so on. [41] MIL-125, an active photocatalyst, includes cyclic octamers of TiO 2 octahedra. [42,43] ZIF-67 has a tunable pore aperture, highly stable structure, and catalytic activity. [37,44,45] The above-mentioned MOFs have been widely used for gas adsorption, molecular separation, catalysis, batteries, supercapacitors, and so on. [13,14,33] Moreover, carbon hybrids containing nanostructured metal species (e.g., metal oxides (MOs)) are likely to form under in situ carbonization conditions. [46] Compared with the carbonaceous materials from conventional precursors, MOF-derived carbon materials have significant advantages with high specific surface areas, tailorable porosities, unique morphologies, and easy functionalization with other heteroatoms. [14,23,31] For example, Xu and co-workers [47] obtained 1D carbon nanorods via the pyrolysis The applications of carbon and carbon-based materials with high porosity, high surface area, and functionalities based on metal-organic framework precursors and/or templates have attracted significant research interest in recent years, particularly in the field of batteries. The chemical and physical properties of carbon and carbon-based materials obtained by the heat treatment of various metal-organic ...

Transition metal sulfides (TMSs) are considered as the most promising alternative anode materials for advanced lithium-ion batteries (LIBs). Here, we report a hierarchically structured CoS 2 nanosphere/graphene (CoS 2 /G) composite, fabricated by a simple hydrothermal method. This composite, assembled with CoS 2 nanoparticles uniformly distributed on the graphene, exhibits excellent electrochemical performance. In particular, the CoS 2 /G electrode material delivers a high rate capability of around 398 mA h g À1 at a current density of 3500 mA g À1. Moreover, a discharge capacity of about 400 mA h g À1 can be obtained after 1000 cycles at a current density of 500 mA g À1. X-ray absorption spectroscopy is used to characterize the sample for the first time, and the results demonstrate that CoS 2 /G is reduced to metallic Co and Li 2 S when discharged to 0.01 V. In subsequent charge-discharge processes, the metallic Co cannot be fully oxidized to CoS 2 , which is the main cause of capacity loss for the CoS 2 electrode.
