Mg‐Gradient Polyacrylonitrile Nanofiber Layer Enabling Li Coble Creep and Stress Relaxation in Anode‐Free All‐Solid‐State Batteries

open access: yesCarbon Energy, EarlyView.
A Mg‐gradient polyacrylonitrile nanofiber (PAN@Mg) layer is introduced on the current collector. This 2‐μm‐thick layer regulates Li diffusion via the Coble creep mechanism, preventing direct Li–solid electrolyte contact. Its elasticity effectively mitigates stress, preserving interfacial integrity during cycling. This approach enables highly reversible

Correlating the Interfacial Chemistries With Ion Conduction and Lithium Deactivation in Hybrid Solid Electrolytes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The rapid ion transport characteristics of nano‐Li2S at the intrinsic/extrinsic interface in typical hybrid electrolytes have been detected at the atomic scale, enabling the Li || Li cell to cycle for over 3000 h. Inactive lithium (dead Li) is the key factor leading to the performance degradation of solid‐state Li metal batteries.

Evaluation of Ecological Environment Quality and Analysis of Influencing Factors in Wuhan City Based on RSEI

open access: yesSustainability
It is crucial to assess the quality of ecological environments in urban areas and investigate the driving forces that would affect urban ecological environments. Utilizing the GEE platform, RSEI was computed by us for Wuhan from 1990 to 2020. Employing geodetector tools and the PLS-SEM approach, driving factors for ecological environment quality in ...

One‐Pot Spray Pyrolysis Fabrication of Multi‐Phase Lithium Manganese Oxide Microsphere Cathodes for Enhanced Lithium‐Ion Battery Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sr‐LMO microspheres were synthesized by one‐pot spray pyrolysis, forming multi‐phase lithium manganese oxide with Sr‐doped LiMn2O4, Sr2Mn2O5, and Li2MnO3‐like domains. This structure refines particles, suppresses Jahn–Teller distortion, and adds Li+ pathways, delivering superior cycling stability and rate performance over undoped and commercial LMO ...

An improved RSEI-based evaluation for effective forest area by integrating forest structure and quality

open access: yesFrontiers in Environmental Science
IntroductionEcosystem stability confers more abundant and comprehensive ecosystem service values. However, current valuation methods often simplify these ecosystems as undisturbed, ideal, and standardized—neglecting inherent variations in structure and quality—and thereby risk skewing service valuations.MethodsWe propose a coupled calculation model ...

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 ...
