Abstract The theoretically high‐energy‐density lithium–sulfur batteries (LSBs) are seriously limited by the disadvantages including shuttle effect of soluble lithium polysulfides (LiPSs) and sluggish sulfur redox kinetics, especially for most difficult solid–solid conversion Li 2 S to S. Herein, a multifunctional catalytic interlayer improve performance LSBs is tried introduce, in which Fe 1– x S/Fe 3 C nanoparticles embedded N/S dual‐doped carbon network (NSC) composed nanosheets nanotubes...
Abstract The inevitable shuttling and slow redox kinetics of lithium polysulfides (LiPSs) as well the uncontrolled growth Li dendrites have strongly limited practical applications lithium‐sulfur batteries (LSBs). To address these issues, we innovatively constructed carbon nanotubes (CNTs) encapsulated Co nanoparticles in situ grown on TiN‐MXene nanosheets, denoted TiN‐MXene‐Co@CNTs, which could serve simultaneously both sulfur/Li host to kill “three birds with one stone” (1) efficiently...
Hollow and hybrid nanomaterials are excellent electrocatalysts on account of their novel electrocatalytic properties compared with homogeneous solid nanostructures. In this report, NiSe-Ni3Se2 nanostructure morphology hollow hexagonal nanodisk was synthesized in situ graphene. A series NiSe-Ni3Se2/RGO different phase constitutions nanostructures were obtained by controlling the durations solvothermal treatment. Because unique structure, nanodisks exhibited higher performance than NiSe/RGO...

Abstract Lithium‐sulfur batteries (LSBs) have become one of the most powerful candidates for next‐generation battery technologies due to their high theoretical energy density and low cost. However, notorious shuttle effect soluble lithium polysulfides (LiPSs) sluggish conversion reaction kinetics cause sulfur utilization inferior cycle life. Rational catalyst design on hierarchical pore structures composition optimization is highly desired realize synergetic enrichment, accommodation,...
For practical lithium-sulfur batteries (LSBs), the high sulfur loading and lean-electrolyte are necessary conditions to achieve energy density. However, such extreme will cause serious battery performance fading, due uncontrolled deposition of Li
Composites of TiO2-B nanorods and reduced graphene oxide (RGO) were prepared through a simple two-step hydrothermal process followed by subsequent heat treatment in argon. The obtained had small size (∼10 nm diameter the nanorod) uniform morphology. Importantly, synergistic effect RGO nanosheets nanostructured leads to electrodes composed TiO2-B-RGO nanocomposites which exhibit excellent cycling stability rate capability (260 mA h g(-1) at 1 C 200 2 after 300 cycles 140 20 C).
Abstract Practical application of lithium–sulfur (Li–S) batteries is severely impeded by the random shuttling soluble lithium polysulfides (LiPSs), sluggish sulfur redox kinetics, and uncontrollable growth dendrites, particularly under high loading lean electrolyte conditions.

The N‐TiO (B)‐MXenes show reduced...
