Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) have attracted increasing attention in energy storage owing to their high energy density, low redox potential, and cost‐effectiveness. Nevertheless, uncontrolled dendrite accumulation, gas generation, and severe side‐reaction problems hinder the cycling lifespan, which prevents their commercial applications ...

, 2021 本发明公开了一种锂电池剩余寿命预测方法，主要采用基于自回归(AR)时间序列和扩展卡尔曼粒子滤波算法(EKPF)的寿命预测方法，包括两个阶段，即经验退化模型构建阶段与寿命预测阶段。第一阶段，退化模型构建阶段，首先构建基于库仑定律的电池容量衰退的双指数模型，它描述了电池可用容量与时间的变化关系，反映浓差极化和两级极化带来的电池容量损失。通过对双指数模型加以改造变形适应状态转移方程的形式，形成变形的经验退化模型，减少了原始模型的参数个数，降低了参数训练的复杂度。第二阶段，寿命预测阶段 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Size‐controllable Sn nanoparticles are designed in this work via oxide doping to be uniformly embedded into flexible N‐doped carbon nanofibers, in which the agglomeration and migration of Sn are effectively restrained due to the suppressive effect of selected oxides, including SiO2, TiO2, and ZnO. Benefiting from unique merits of the embedment

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The stability of aqueous Zn2+ batteries is severely hindered by parasitic reactions at the Zn anode/electrolyte interface. Herein, itaconic acid (IA) is introduced as an effective electrolyte additive to achieve a highly stable zinc anode. Remarkably, IA concurrently modulates both the zinc anode/electrolyte interfacial structure and the Zn2 ...

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 ...
