RuO2‐Based High‐Entropy Oxide and Its Asymmetric Catalysis on Polysulfide Conversion in Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
RuO2‐based high‐entropy metal oxide shows an asymmetric catalysis on polysulfide conversion with an inferior kinetics enhancement of polysulfide generation, but a superior promotion of Li2S deposition, which greatly favors the inhibition of shuttle effect and the improvement of battery performance. High‐entropy oxides with five or more metal components

Tuning S Doping in Porous Carbon for Enhanced Initial Coulombic Efficiency and Rate Performance for Sodium/Potassium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Low‐temperature carbonization and sulfur doping increase defect density and tailor surface area, enabling the formation of a thinner, more stable SEI, enhancing rate performance and the ICE. The S/C composite delivers an ICE of 83.1% and 480 mAh g−1 at 0.1 A g−1, retaining 232.6 mAh g−1 at 5 A g−1 for SIBs and achieves a considerable capacity of 439.2 ...

Confinement−Adsorption Synergy in Hybrid Carbon‐Coated Separator Enables Stable High‐Rate Quinone Cathode for Magnesium Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sulfur‐containing heterocyclic quinone cathode for rechargeable magnesium batteries is coupled with a GO/MWCNTs–COOH separator that establishes a confinement–adsorption regulation mechanism, thereby significantly accelerating Mg2+ reaction kinetics and minimizing active‐material loss.
