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 ...

Se‐Vacancy Engineering Enables Dual Electronic and Interfacial Regulation in SnSe2 Nanocatalysts for High‐Performance Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Se vacancies in SnSe2 induce local electron redistribution and create unsaturated Sn sites, enabling a switch from single‐site to dual‐site adsorption of lithium polysulfides. This structure synergistically enhances redox kinetics, accelerates sulfur conversion, suppresses the shuttle effect, reduces polarization, and significantly improves the ...

Control Mechanism of Pore Structure of Different Macroscopic Lithotypes on Gas Desorption Differences: A Case Study of High‐Rank Coal From the Western Ordos Basin

open access: yesEnergy Science &Engineering, EarlyView.
论文陈述 Paper Statement 本研究揭示了不同宏观煤岩类型的差异化控气机制:半亮煤是主要“储气核心,” 光亮煤为关键“渗流通道,” 暗淡煤则是“初期高产贡献者”。这为深层煤层气甜点优选与定制开发提供了关键理论依据。 This study reveals the differentiated gas‐controlling mechanisms of different macroscopic coal lithotypes: semibright coal acts as the primary “gas storage core,” bright coal serves as the critical “seepage channel,” and dull coal functions
