“…[49] This review focuses on the application of MOF-derived carbon materials for batteries (including LIBs, Li-S batteries, SIBs, Li-O 2 batteries, Li-Se batteries, Zn-air batteries, Na-S batteries, Li-Te batteries, and Na-Se batteries). [61][62][63][64][65][66] Unfortunately, these materials are unable to substitute for graphite in industrialization because of the poor electronic conduction, large volume change, and failure to maintain its integrity during the charge/discharge cycles. Shen et al [25] reviewed the development of MOF-derived carbon-based materials for efficient catalysis.…”

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 ...

“…Thus, the ratio of the absolute peak intensities I D /I G indicates the degree of graphitization of the composites ,. The value of I D /I G for both LTO/Gr and LTO/CNTs is ∼0.5 and ∼1.0, respectively, suggesting that the degree of graphitization of carbon in graphene is higher than that in CNTs sample; this implies a higher electrical conductivity and an increase of the rate capability of the LTO/Gr electrode …”

Three‐dimensional composites Li2TiO3/graphene (LTO/Gr) and Li2TiO3/carbon nanotube (LTO/CNTs) were synthesized by solid‐state reaction for application as anode materials for lithium‐ion batteries. These composites are structurally characterized by X‐ray diffraction, Raman spectroscopy and high‐resolution transmission electron microscopy, while electrochemically tests are performed by cyclic voltammetry and chronopotentiometry. The synergetic effect of graphene and CNTs with LTO facilitate the network conduction leading to faster electron and Li+ ion transfer and improve cycling stability and rate capability of the anode. The LTO/Gr and LTO/CNTs composites exhibited an initial discharge capacity as high as 154 and 149 mAh g−1 at 1C rate, respectively and retained excellent cycling stability of 98% and 96% after 30 charge–discharge cycles.

“…Therefore, the much better rate capability of the 3D HD‐FMN electrode is achieved than those of the MoS 2 nanosheets and 3D FNN. In addition, the Z ′ − ω −1/2 (ω = 2 πf , f represents the frequency) curves in the low‐frequency region for the three samples after the rate performance test are shown in Figure d, and the low slope means a good lithium‐ion kinetics in the active electrode materials . As can be distinctly seen, the slope of 3D HD‐FMNs (29.3) is significantly lower than those of 3D FNN (62.9) and MoS 2 nanosheets (76.3), indicating a high Li + ‐ion diffusion coefficient in the 3D HD‐FMN electrode.…”

Owing to unique lamellar nanostructures, 2D inorganic materials are considered as promising candidates in energy storage and conversion. In this paper, a facile two‐step synthesis is developed to fabricate 3D hierarchical dual Fe3O4/MoS2 nanosheets (HD‐FMNs), in which few‐layered MoS2 nanosheets are anchored in 3D Fe3O4 nanosheet network to form the heterojunction structure. Furthermore, it is proved that the synergistic effects on both electron/lithium‐ion transport kinetics and mechanical cycling stability benefit from Fe3O4/MoS2 nanosheet incorporation in 3D HD‐FMN anode for lithium‐ion batteries (LIBs), resulting in the dramatically enhanced performance. The Fe3O4 nanosheet incorporation effectively improves the electronic conductivity due to its half‐metal characteristic, while the defect‐rich structure in the MoS2 nanosheets can facilitate the lithium ion transport. When tested as potential anode materials, 3D HD‐FMNs exhibit a high reversible capacity (650 mAh g−1) at current rate of 5 C (1 C = 1 A g−1) after superior long‐term cycles (1000 times), as well as an excellent rate capability even at high current rates. The outstanding electrochemical property of 3D HD‐FMNs allows their application in high‐performance anode materials for next‐generation LIBs. This strategy also opens a new way to design the novel 2D composite materials for electrochemical devices.
