“…They anchored Mo 2 C nanoparticles on CNTs (Mo 2 C/CNT) to serve as cathode material for the Li-S battery to achieve strong chemical interaction with LiPSs and deliver a high catalytic performance. [65] Black phosphorus has been used to alleviate shuttle effect since PLi bonds can be formed because of the lipophilic interaction. It is mentionable that CNTs with conductive framework can ensure fast charge transport and reduce additional surface diffusing step, which can also enhance the reaction kinetics.…”

Lithium‐sulfur (Li‐S) batteries are one of the most promising next‐generation energy‐storage systems. Nevertheless, the sluggish sulfur redox and shuttle effect in Li‐S batteries are the major obstacles to their commercial application. Previous investigations on adsorption for LiPSs have made great progress but cannot restrain the shuttle effect. Catalysts can enhance the reaction kinetics, and then alleviate the shuttle effect. The synergistic relationship between adsorption and catalysis has become the hotspot for research into suppressing the shuttle effect and improving battery performance. Herein, the adsorption‐catalysis synergy in Li‐S batteries is reviewed, the adsorption‐catalysis designs are divided into four categories: adsorption‐catalysis for LiPSs aggregation, polythionate or thiosulfate generation, and sulfur radical formation, as well as other adsorption‐catalysis. Then advanced strategies, future perspectives, and challenges are proposed to aim at long‐life and high‐efficiency Li‐S batteries.

“…Compared with the traditional physical confinement of soluble LiPSs, the chemical adsorption/binding interaction presents stronger anchoring ability [17][18][19][20][21] . In this section, we summarize the research progress of various materials that were designed to chemically adsorb soluble LiPSs, including heteroatom-doped materials, various polymers, nitrides, oxides, sulfides, hydroxides, MXenes, and carbides.…”

However, these additional weights inevitably reduce the energy density of batteries.…”

Lithium-sulfur (Li-S) secondary batteries have been limited by the poor cyclic stability, mainly caused by the dissolution polysulfide species into the electrolyte and subsequent irreversible shuttling effect. Recently, addition of the polysulfide adsorbents within sulfur cathode is effectively improving the electrochemical performance. Herein, TiO 2 integrated with g-C 3 N 4 (TiO 2 @g-C 3 N 4 : TOCN) hybrid was prepared by a facile heating treatment from the precursor of urea and TiO 2 composites, which used as host material for elemental sulfur (TOCN@S) in Li-S batteries. The multifunctional TOCN not only reduced the electrochemical resistance but also provided strong adsorption sites to immobilize sulfur and polysulfide. As a result, the TOCN@S cathode with a sulfur content of 74.5 wt% and a sulfur loading of 3.1 mg cm −2 exhibits a high initial capability of 804 mAh g −1 at 0.5 C with capacity retention of 67.2% after 500 cycles. Additionally, the composite cathode also possesses excellent high-rate performance, retaining a remarkable specific capacity of 630 mAh g −1 even at a rate of 2 C.
