Enhancing the cut-off voltage of high-nickel layered oxide cathodes is an efficient way to obtain higher energy density of lithiummetal batteries(LMBs).However,the phase transition of the cathode materials and the uncontrolled decomposition of the electrolytes at high voltage can lead to irreversible dissolution of transition metal ions,which might cause the crossover effects on the lithium metal ***,the mechanism and electrolyte dependence of the crossover effects for Li metal anodes are still ***,we investigate the crossover effects between LiNi_(0.8)Mn_(0.1)Co_(0.1)O_(2)and Li-metal anode in two electrolyte *** ether-based electrolyte,its poor oxidation stability results in massive dissolution of transition metal ions,leading to dendrite growth on anode and rapid cells ***,ester-based electrolyte exhibits good electrochemical performances at 4.5 V with little crossover *** study provides an idea for electrolyte systems selection for high-voltage LMBs,and verifies that the crossover effect should not be neglected in LMBs.

Insights into the room–temperature hydrogen sensing mechanism of metal/oxide Schottky diodes by regulating interfacial adsorbed oxygen/ hydroxyl

引用

International Journal of Hydrogen Energy 2025年 138卷 183-192页

作者： Li, Ruiwu Xu, Ziqin Qian, Delai Yan, Liqing Yang, Cheng Xie, Guomeng Fang, Haitao School of Materials Science and Engineering Harbin Institute of Technology Harbin150001 China State Key Laboratory of Space Power–Sources Technology Shanghai Institute of Space Power–Sources Shanghai200245 China

Implanting a high–dielectric insulating interlayer between the metals and semiconductors of hydrogen sensing diodes can improve the response, yet the underlying mechanism remains unclear. This study examines key factors for the improved hydrogen response by regulating interfacial adsorbed oxygen and hydroxyl (Oi–ads/OHi–ads) through heat treatment. Heat treatment at 100 °C or 150 °C reduces the Oi–ads/OHi–ads content of as–prepared Pt/TiO2 diode, leading to an alleviated FLP effect and aggravated leakage current. The as–prepared Pt/TiO2 and Pd nanoparticles (Pd NPs) decorated Pt/TiO2 diodes show weak response (2, while heat treatment at 100 °C for 1 h significantly enhances their responses, reaching 325 and 7 × 103, respectively. Moreover, increased interfacial hydrogen by incomplete recovery in dry air subsequently results in higher response. Therefore, the alleviated FLP effect and the increased interfacial hydrogen are crucial factors for boosted hydrogen response. © 2025 Hydrogen Energy Publications LLC

Designing economical oxygen evolution reaction(OER) electrocatalysts with high activity and long-term stability is essential to promote the scale-up applications of proton exchange membrane water electrolyzer(PEMWE) for hydrogen production. Ruthenium(Ru)-based materials with high intrinsic activity are hailed as the most promising catalysts, but still infeasible for practical application considering their long unresolved poor stability(only dozens of lifespan). Thus, tremendous efforts have been devoted to uncovering the degradation mechanisms and developing stabilization strategies for the Ru-based catalysts. In this review, starting from summarizing the fundamental understanding of deactivation mechanisms, a picture of the stability issue of Ru-based catalysts is proposed, which is followed by a detailed discussion on the recently developed strategies and progress made on enhancing durability. Finally, insights on the prospects for the future development of stable and practical Rubased OER catalysts are provided.

Topochemical transformation has emerged as a promising method for fabricating two-dimensional (2D) materials with precise control over their composition and morphology. However, the large-scale synthesis of ultrathin 2D materials with controllable thickness remains a tremendous challenge. Herein, we adopt an efficient topochemical synthesis strategy, employing a confined reaction space to fabricate ultrathin 2D Sn_(4)P_(3) nanosheets in large-scale. By carefully adjusting the rolling number during the processing of Sn/Al foils, we have successfully fabricated Sn_(4)P_(3) nanosheets with varied layer thicknesses, achieving a remarkable minimum thickness of two layers (~ 2.2 nm). Remarkably, the bilayer Sn_(4)P_(3) nanosheets display an exceptional initial capacity of 1088 mAh·g^(−1), nearing the theoretical value of 1230 mAh·g^(−1). Furthermore, we reveal their high-rate property as well as outstanding cyclic stability, maintaining capacity without fading more than 3000 cycles. By precisely controlling the layer thickness and ensuring nanoscale uniformity, we enhance the lithium cycling performance of Sn_(4)P_(3), marking a significant advancement in developing high-performance energy storage systems.
