Synthesis of three-dimensionally interconnected sulfur-rich polymers for cathode materials of high-rate lithium-sulfur batteries [PDF]

Elemental sulfur is one of the most attractive cathode active materials in lithium batteries because of its high theoretical specific capacity. Despite the positive aspect, lithium-sulfur batteries have suffered from severe capacity fading and limited ...

Gradient‐Modified Li‐Rich Manganese‐Based Oxides Cathodes with Breakthrough of Kinetic Limitation for High‐Performance All‐Solid‐State Lithium Metal Batteries

Advanced Materials, EarlyView.
The novel gradient‐modified LRMO has been synthesized via a one‐step mechano‐fusion process, with simultaneous S and Zr co‐doping in the near‐surface region and an amorphous coating. The synergistic co‐functionalization stabilizes the oxygen framework, enhances charge transport, and suppresses oxygen dimerization under high potential, which enable ...

Oxygen Vacancies on Layered Niobic Acid Weaken the Catalytic Conversion of Polysulfides in Lithium Sulfur Battery.

Angewandte Chemie, 2019
Oxygen vacancies are usually considered as beneficial in catalytic conversion of polysulfides in lithium sulfur battery. In this work, we demonstrated that the conversion of polysulfides was hindered by creating oxygen vacancies on ultrathin layered ...
