Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Bismuth anode materials are considered promising anode candidates for sodium–ion batteries (SIBs) due to their high theoretical capacity and appropriate working potential. Nevertheless, the significant volume expansion that occurs during the cycling process restricts its broader application in sodium–ion storage. Herein, Bi/Bi2O3 nanoparticles

Gaoya dianqi, 2006 线路附近地面的场分布是输电线路电磁环境中的一个重要指标。首先验证了半经验公式法的有效性。然后使用该方法分析了极导线水平排列的±800 kV直流线路合成场强、标称场强和离子流密度的影响因素和变化规律。研究表明地面,标称电场强度受线路对地高度的影响很大,而合成电场强度和离子流密度除受导线对地高度的影响较大外,受导线直径和分裂数的影响也很大。

In Situ Formation of the Li3Bi Alloy Phase Interface for Robust Garnet Solid‐State Lithium Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Garnet‐type electrolyte Li6.4La3Zr1.4Ta0.6O12 (LLZTO) is a promising component for commercializing solid‐state batteries owing to its wide electrochemical window, good stability, and high shear modulus. However, poor interface wettability and lithium dendrite growth limit the practical application of the LLZTO electrolyte.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Driven by global energy transition and sustainability, sodium‐ion batteries (SIBs) have emerged as key alternatives to lithium‐ion batteries for low‐to‐medium energy storage, because of abundant sodium resources and low cost. However, their commercialization is hindered by the lack of anodes with high capacity, fast kinetics, and long‐term ...

Gaoya dianqi, 2013 高压直流输电线路发生电晕放电时,周围空间会充满带电离子,从而使空间电场显著增强。为了准确计算地面离子流场,文中采用该有限元—积分法对双极离子流场的控制方程进行求解。文中在计算合成电场时采用了有限元外推法,同时还对空间电荷密度初值进行了改进。通过利用该方法对同轴圆柱模型和±400 kV的直流线路进行的比对计算,验证了该算法的有效性。同时,在实际的±500 kV直流线路上,把该算法的计算结果与已有算法的计算结果进行了对比。实际线路验证和算法间对比均表明,该方法具有较好的精度。最后,采用所提出的方法对±800
