Correction to “Polysulfide Regulation by the Zwitterionic Barrier toward Durable Lithium–Sulfur Batteries”

Hierarchically Porous Ti3C2 MXene with Tunable Active Edges and Unsaturated Coordination Bonds for Superior Lithium–Sulfur Batteries

“…Among these materials, MXene exhibits abundant terminated functional groups, which can provide adequate binding energy to anchor polysulfides, thus avoiding the dissolution and shuttling of polysulfides in electrolyte. For example, Tang et al reported that the in situ formed sulfate complex on MXene surface during repeated cycling can serve as a protective barrier, which effectively inhibits the shuttle effect and promotes the sulfur utilization. , In addition, with excellent metallic conductivity and abundant active sites on the surface, MXene ensures fast electron transportation and improved redox reaction kinetics when serving as sulfur electrocatalyst, leading to accelerated LiPS adsorption and catalytic conversion. − However, the aggregation and restacking tendency of MXene sheets result in limited surface area and insufficient exposure of active sites, conferring slowed electron/ion transportation . To prevent the restacking, the most common strategy is to integrate the 2D nanosheets into a 3D porous structure.…”

Nano‐LaMnO3 Modified Separator for Enhanced Redox Reaction Kinetics and Electrochemical Performance of Lithium‐Sulfur Batteries

“…Some polar compounds (such as metal oxides/sulfides/nitrides) were preferred as surface modification on the separator for chemically immobilizing and then catalyzing the rapid conversion of long-chain polysulfides, reducing their dissolution and shuttling in the electrolyte. [15][16][17][18][19] However, the capacity fading is still frequently observed because of various inherent defects of the coating materials, e. g., poor conductivity, weak adsorption or catalysis capability towards polysulfides. [20] Recently, perovskite oxides characterized by stable crystal structure, adjustable redox activity, high thermal stability and good ionic/electronic conductivity, [21][22][23][24] have attracted much attention as a class of intrinsically efficient electrocatalysts applicable for fuel cells, metal-air batteries and NO/CO removal industries.…”

An Ultrathin Functional Layer Based on Porous Organic Cages for Selective Ion Sieving and Lithium–Sulfur Batteries

“…With the high theoretical specific capacity (1673 mAh/g) of a sulfur cathode, lithium–sulfur (Li–S) batteries have been regarded as one of the most promising candidates for next-generation energy storage systems. , However, one of the major challenges preventing the commercialization of lithium–sulfur batteries is the “shuttle effect” caused by the dissolution and migration of polysulfide species in organic electrolytes during battery charging and discharging; this causes the loss of active sulfur and eventually leads to poor cycle life of the battery. To address the aforementioned issue, various approaches, including both physical confinement , and chemical absorption, − have been actively explored. A key challenge is to maximize the selectivity of the materials so that lithium ions can pass through and polysulfide ions are blocked.…”

“…A key challenge is to maximize the selectivity of the materials so that lithium ions can pass through and polysulfide ions are blocked. Many efforts have been devoted to the design and development of materials for this purpose, including porous carbon materials, ,− polymer materials, ,, inorganic materials, ,, MOFs, ,− and COFs. , Nevertheless, it is still challenging to design a material with both precise control over pore structure at the molecular level for selective ion transport and proper functional groups for chemical absorption (Figure S3).…”
