“…An irreversible cathode peak appeared in the first cycle, due to the nonaqueous electrolyte decomposition and solid electrolyte interface (SEI) film formed during the discharge process . According to previous reports about transition metal selenide as the anode of lithium‐ion batteries, the discharge process can be summarized as Equations (2)–(4) . According to the subsequent cycles, three cathodic peaks are observed at 1.85 V, 1.35 V, and 0.25 V, respectively.…”

In recent years, lithium‐ion batteries (LIBs) have been widely used in many fields, and research on LIBs electrode materials have attracted much attention. Among them, transition metal selenides (TMSs) are the most promising candidates in the next generation LIBs due to their high theoretical specific capacity and electrical conductivity. However, poor cycle stability and severe volume variation result in serious capacity decay during the charge/discharge process, limiting the practical application. In this paper, CoSe2−MnSe2 composites are synthesized via Co−Mn‐based metal‐organic framework (MOF) precursor. Meanwhile, three types of materials are successfully synthesized including CoSe2‐MnSe2@reduced graphene oxide (rGO), CoSe2‐MnSe2@polypyrrole (PPy), and CoSe2‐MnSe2/glucose (C). According to the electrochemical test results, it can be seen that the electrochemical performance of CoSe2−MnSe2 has been improved significantly. CoSe2‐MnSe2@rGO electrode materials, in particular, of which the inactivation defect sites and special carbon structure of rGO could provide more attachment points for ions. Due to the perfect combination of rGO and CoSe2−MnSe2, the CoSe2‐MnSe2@rGO composites display outstanding rate performance (1266 mA h g−1 at current densities of 100 mA g−1) and high reversible capacity (1169 after 150 cycles at 100 mA g−1). We believe that CoSe2‐MnSe2@rGO is a kind of very promising anode material.

In recent years, metal‐organic frameworks, especially MOF‐based derivatives, have been regarded as one of the best candidate electrode materials for the next generation of advanced materials, due to high porosity, large surface area, modifiable functional groups as well as controllable chemical composition. This review presents the corresponding synthesis methods, structural design, and electrochemical performance of MOF‐derived materials, including metal oxides, metal sulfides, metal phosphides, and carbon materials, in high‐performance lithium‐ion batteries. Subsequently, the problems that exist in the current application of MOF‐based derivatives as electrodes in lithium‐ion batteries are discussed along with possible and feasible solutions. At last, some reasonable pathways and strategies for the design of MOF derivatives are also suggested.

Metal–organic frameworks (MOFs) or covalent–organic frameworks (COFs) have gained increasing attentions due to their high surface area, tunable structure, highly ordered pores and functional composition. Besides their applications in gas adsorption and separation, hydrogen storage, optics, magnetism and drug delivery, they have been widely employed as cathodes, anodes and separators for the research and development in lithium‐ion batteries (LIBs) due to the tunable structure, multi‐electron transfer, short pathway, and robust structural stability, etc. This review summarizes the general applied strategies and cases of MOF, COF and their composites as well as derivatives in LIBs. Compared to inorganic materials, the advantages of MOF/COF materials have made it possible to witness various successful cases with enhanced electrochemical performances. Moreover, this review provides some guidance for the controllable preparation and modification of MOF‐ and COF‐derived nanostructures through molecular engineering, rational design, and doping, as well as functional group modifications. In addition, we highlight timely progresses of the application of organic frameworks in LIBs, and also summarize many strategies of MOF/COF materials and their derivatives on enhancing the energy density, diffusion coefficient, rate performance and cycling stability for next‐generation LIBs with attractive features of high energy density, good rate performance, and superior cyclability.
