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 ...

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

open access: yesENERGY &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

Engineering in‐plane porosity in MXenes for energy storage: Correlating synthesis strategies with pore structure control

open access: yesInfoMat, EarlyView.
MXenes are considered highly promising next‐generation energy storage materials due to their exceptional physicochemical and electrochemical properties, yet their electrochemical performance is severely hindered by nanosheet restacking. Constructing in‐plane pores directly on MXene nanosheets has emerged as an effective strategy to accelerate ion ...
