Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Two‐dimensional (2D) nonlayered niobium nitrides have attracted considerable interest for electrochemical energy storage. However, the synthesis of these materials is hampered by their nonlayered crystal structures, which are characterized by strong three‐dimensional chemical bonding.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Biomass‐derived quinones are promising green and sustainable cathode materials for sodium‐ion batteries (SIBs), yet their practical application is hindered by poor cycling stability due to dissolution in conventional electrolytes. Herein, we demonstrate that sodiumation is an effective strategy to enhance both rate capability and cycling ...

Gaoya dianqi, 2008 考虑到气象因子条件对绝缘子的等值附盐密度影响复杂,难以建立精确数学模型等问题,提出了一种最小二乘支持向量机的绝缘子在一定的气象因子条件下的等值附盐密度预测新模型。以温度、湿度、风速等主要气象因子为输入,绝缘子等值附盐密度为输出,通过最小二乘支持向量机模型,拟合输入与输出之间的复杂非线性函数关系。以现场采集的气候数据为样本对模型进行学习训练,用训练好模型预测绝缘子在一定气候条件下的等值附盐密度。实践表明该方法具有建模速度快、预测精度高、操作简便等优点,不仅克服了常规的BP预测模型的不足 ...
