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 ...

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

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

Synthesis and characterization of zinc glycinate monohydrate(一水合甘氨酸锌螯合物的合成及其表征)
Zhejiang Daxue xuebao. Lixue ban, 2008 简化了甘氨酸锌螯合物的合成，以甘氨酸和碱式碳酸锌为原料，按摩尔比为2 ： 1的比例在水相中合成，90~95 ℃间反应6 h，得到了产率为94.6%的水合甘氨酸锌螯合物.产品经纯化处理后用元素分析、红外光谱、紫外光谱、热重分析、粉末衍射等一系列方法进行表征.结果表明该螯合物是带一个结晶水的分子化合物，摩尔电导率为20.1 Scm2 • mol-1，稳定常数为2.29×105.另外用凝胶色谱法测定了该螯合物的螯合率，得螯合率为100%±1%.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Chemically self‐charging aqueous zinc‐ion batteries (AZIBs) have emerged as promising candidates for energy storage technologies owing to their environmental autonomy and structural simplicity. Nonetheless, the self‐charging performance is significantly compromised by the limited potential difference between cathodes and oxygen, as well as the
