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

ENERGY &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

ENERGY &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

ENERGY &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.

Interfacial Solvent Molecular Engineering via High‐Safety Dense Separators for High‐Rate Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The dense PPS‐separator prevents thermal runaway by allowing electron transfer through the steel needle during penetration, while the residual electrolyte enables brief ion migration and Joule heating, causing rapid electrolyte vaporization, collapse of the ion transport network, and a sharp drop in ionic conductivity.

Engineering Nanoclay Edges to Construct Effective Polysulfide‐Trapping Interface for Markedly Enhanced Electrochemical Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A capsule‐shaped silicate clay (H‐ATP‐N2) rich in protonated edge hydroxyl groups (‐OH2+) is synthesized through a two‐step process involving microwave‐assisted acid treatment and N2 plasma etching to fibrous natural attapulgite. The H‐ATP‐N2 host inhibits the shuttle effect owing to the dominant adsorption mechanism–Lewis acid–base interaction between
