“…Within the structure, each S 2− anion is coordinated with eight Li + cations and each Li + is surrounded by four S 2− anions, [ 24 ] producing large cavities in the crystal structure. [ 25 ] Similar to all other antifluorite‐structured materials, Li 2 S has the properties of high melting and boiling point, high enthalpy of formation, a wide band gap, high solubility in polar solvents, and low density.…”

The great demand for high‐energy‐density batteries has driven intensive research on the Li–S battery due to its high theoretical energy density. Consequently, considerable progress in Li–S batteries is achieved, although the lithium anode material is still challenging in terms of lithium dendrites and its unstable interface with electrolyte, impeding the practical application of the Li–S battery. Li2S‐based Li‐ion sulfur batteries (LISBs), which employ lithium‐metal‐free anodes, are a convenient and effective way to avoid the use of lithium metal for the realization of practical Li–S batteries. Over the past decade, studies on LISBs are carried out to optimize their performance. Herein, the research progress and challenges of LISBs are reviewed. Several important aspects of LISBs, including their working principle, the physicochemical properties of Li2S, Li2S cathode material composites, LISBs full batteries, and electrolyte for Li2S cathode, are extensively discussed. In particular, the activation barrier in the initial charge process is fundamentally analyzed and the mechanism is discussed in detail, based on previous reports. Finally, perspectives on the future direction of the research of LISBs are proposed.

“…Extensive efforts have been devoted to constructing the cathode of lithium–sulfur (Li–S) batteries to meet the ever‐increasing energy demands due to the abundant reserves of the materials involved, and affordable cost. [ 1–3 ] However, the commercial application of the sulfur cathode for the Li–S batteries is restrained by several technical barriers [ 4–6 ] compared with Li‐ion battery. [ 7 ] First, the poor conductivity of sulfur and its reaction intermediates limit the sulfur utilization, [ 8 ] which leads to decreased energy density and power density.…”

involved, and affordable cost. [1][2][3] However, the commercial application of the sulfur cathode for the Li-S batteries is restrained by several technical barriers [4][5][6] compared with Li-ion battery. [7] First, the poor conductivity of sulfur and its reaction intermediates limit the sulfur utilization, [8] which leads to decreased energy density and power density. Second, during the charge/discharge process, there is a large volume change, resulting in rapid deterioration of the electrode structure. Various strategies have been investigated to increase electrode conductivity and to accommodate the volume expansion. [9][10][11] Last but not least, the dissolution and transport of lithium polysulfides (LiPSs) in the electrolyte result in the fatal "shuttle effect" that causes the deposition of Li 2 S on Li anode and then degrades the cycle performance. This shuttle effect could be mitigated by 1) trapping/confining the soluble LiPSs in the cathode by physical and chemical adsorption, [12][13][14][15] which prevents the transport of soluble LiPSs in the electrolyte, and 2) enhancing the kinetics of LiPS conversion reactions so that the soluble long-chain LiPS could transform to insoluble short-chain LiPS quickly, limiting the lifetime of soluble LiPS. [16,17] Therefore, a superior Li-S battery could be achieved by designing a cathode with high electricalThe lithium-sulfur (Li-S) battery is widely regarded as a promising energy storage device due to its low price and the high earth-abundance of the materials employed. However, the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox conversion result in inefficient sulfur utilization, low power density, and rapid electrode deterioration. Herein, these challenges are addressed with two strategies 1) increasing LiPS conversion kinetics through catalysis, and 2) alleviating the shuttle effect by enhanced trapping and adsorption of LiPSs. These improvements are achieved by constructing double-shelled hollow nanocages decorated with a cobalt nitride catalyst. The N-doped hollow inner carbon shell not only serves as a physiochemical absorber for LiPSs, but also improves the electrical conductivity of the electrode; significantly suppressing shuttle effect. Cobalt nitride (Co 4 N) nanoparticles, embedded in nitrogen-doped carbon in the outer shell, catalyze the conversion of LiPSs, leading to decreased polarization and fast kinetics during cycling. Theoretical study of the Li intercalation energetics confirms the improved catalytic activity of the Co 4 N compared to metallic Co catalyst. Altogether, the electrode shows large reversible capacity (1242 mAh g −1 at 0.1 C), robust stability (capacity retention of 658 mAh g −1 at 5 C after 400 cycles), and superior cycling stability at high sulfur loading (4.5 mg cm −2 ).

“…Recently, various organic materials are studied as cathode materials for LIBs because of merits of evenly distributed elements, tunable structures, and high capacities, such as conductive polymers, [248,249] organic sulfur compounds, [250,251] organic radicals and organic carbonyl compounds. [197,[252][253][254] However, the shortcomings have severely limited their practical Table 6.…”

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.
