Silicon (Si) stands out as a superior anode material for LICs due to its compelling attributes, including a high theoretical specific capacity (4200mAh/g) and a low de-lithiation potential. Nevertheless, the inherent

High performance and robust durability proton conductive composite membranes containing CeO2-TiC incorporated sulfonated poly(arylene ether) for hydrogen fuel cells J. Alloys Compd. (IF 5.8) Pub Date : 2024-07-22 Ae Rhan Kim
Degradation of proton exchange membrane (PEM) due to free radicals often decreases the overall performance of proton exchange membrane fuel cells (PEMFC). The incorporation of antioxidative additives into the polymer matrix has been widely exploited to mitigate oxidative degradation but is still challenging. Herein, butylsulfonated poly(arylene ether)(SAFPAE) was synthesized by polycondensation followed

Wear and corrosion resistance of TiAlSi-Nix (x = 0, 5, 11, 17, 23 at%) multi-principal component alloy coating prepared by ∞ oscillating laser cladding J. Alloys Compd. (IF 5.8) Pub Date : 2024-07-22 Minglei Liu, Xiaojie Song, Di Jiang, Guosong Zhang, Yuming Zhu, Hongzhi Cui
To improve the wear and corrosion resistance of key components and ensure the safe operation of offshore equipment, we applied an ∞ oscillating laser to prepare a TiAlSi-Ni composite coating. The effects of Ni addition on the composition, microstructure, corrosion resistance and mechanical properties of the coating were experimentally investigated. The results showed that the coating mainly presented

Defects introducing and heterostructures engineering synergistically constructing active sites for achieving stable and fast ion transport in sodium-ion batteries J. Alloys Compd. (IF 5.8) Pub Date : 2024-07-22 Xiaoyu Wang, Qihang Yang, Kai Li, Mengmeng Zhen
Bronze phase TiO (TiO(B)) has attracted significant interest as potential anode materials for sodium-ion batteries (SIBs) due to its distinctive open tunnel structure, offering abundant insertion sites for Na-ions. However, the practical application has been hindered by its poor electrical conductivity and insufficient Na diffusion kinetics. Herein, we propose a novel strategy that integrates defect
