Rational Design of High‐Performance Nickel‐Sulfur Nanocomposites by the Electroless Plating Method for Electrochemical Lithium‐Sulfur Battery Cathodes

“…[14][15][16][17][18] Among the reported sulfur-based composites, carbon-sulfur nanocomposites dominate because of the high conductivity of carbon and the strong polysulfide adsorption of the porous carbon matrix, which improve the charge-transfer capability of the nanocomposite and the adsorption of dissolved polysulfides, respectively. [3,[19][20][21][22][23] With the fast development of carbon-sulfur nanocomposites, engineering designs that incorporate polar materials and hierarchical morphologies have been applied to carbon substrates to improve their polysulfide-trapping capability. [19][20][21][22][23] Aside from carbon-sulfur nanocomposites, various polymer networks have also been used in synthesizing polymer-sulfur nanocomposites with functional groups that strongly interact with the polysulfide species and thus restrain the dissolution and diffusion of the polysulfides.…”

“…To address the scientific and engineering issues mentioned above, great effort has been devoted to designing and synthesizing various sulfur‐based composites, with the goal of using them as cathodes in lithium‐sulfur batteries that offer sufficient sulfur loading and high sulfur utilization for technological applications and fulfill the energy density target of 500 Wh kg −1 [14–18] . Among the reported sulfur‐based composites, carbon‐sulfur nanocomposites dominate because of the high conductivity of carbon and the strong polysulfide adsorption of the porous carbon matrix, which improve the charge‐transfer capability of the nanocomposite and the adsorption of dissolved polysulfides, respectively [3,19–23] .

SiO 2 blending polyetherimide separator modified with acetylene black/polyvinylpyrrolidone coating layer to enhance performance for lithium‐sulfur batteries

“…In consideration of the above-mentioned challenges in Li-S batteries, many strategies have been put into effect to modify cathode materials, including but are not limited to sulfur/nitrogen doped carbon nanotubes, 9 sulfur/graphene oxide, 10,11 sulfur/metal compound [12][13][14] and sulfur/conductive polymer. [15][16][17] Most researches focus on encapsulating sulfur in host material with specially structure to limit polysulfides.…”

Low-temperature Liquid Exfoliation of Milligram-scale Single Crystalline Few-layer β12-Borophene Sheets as Efficient Electrocatalysts for Lithium–Sulfur Batteries

“…Among many candidates, lithium sulfur (Li-S) batteries have been gaining the global attention due to their overwhelming energy density (2600 Wh kg -1 ), natural abundance and environment-friendly of sulfur feedstock [5][6][7][8][9] . However, the existence of internal polysul de shuttling, large volume expansion of sulfur and sluggish redox kinetics inevitably lead to the sharp deterioration of the electrochemical performances of Li-S batteries [10][11][12] .…”
