Synergistic Engineering of Amorphous Cathode and Hybrid Electrolyte Toward Stable High‐Voltage Aqueous Zn‐Ion Batteries

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The development of high‐voltage aqueous zinc‐ion batteries (AZIBs) is primarily hindered by the lack of suitable cathode materials and electrolytes that can work in broad voltage windows. Herein, we propose a synergistic strategy that concurrently addresses these challenges through the integration of an amorphous vanadium oxyphosphate/graphene

Electronegativity‐Driven Frontier Orbital Engineering in B‐Ti Diatomic Synergy Enables Selective Li2C2O4 Conversion in Li‐CO2 Batteries

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT As a promising alternative to sluggish Li2CO3‐based Li‐CO2 electrochemistry, Li2C2O4 offers a favorable 2e− discharge pathway, yet its selective formation and reversible decomposition remain debated. Herein, we propose a nonmetal‐metal synergistic catalyst—B‐Ti coregulated layered transition metal boride Ti18B18O9/graphene (B‐Ti/TiBOG)—to ...

石墨烯气凝胶/MnO₂复合材料强化电容去离子性能研究

Gongye shui chuli, 2020
选用石墨烯气凝胶（GA）作为载体，负载MnO2纳米颗粒，构建新型石墨烯气凝胶-MnO2复合材料（MnGA），并制备电容电极，研究复合材料的电容去离子性能。结果表明，MnO2在石墨烯片层上可形成一维线状结构，减弱石墨烯片层间的堆叠效应，提升材料电容，从而提高了电极的脱盐性能，最大电容脱盐量达到25.78 mg/g；NaCl溶液的初始浓度、供电电压和进水流速均会对电容脱盐量产生影响。
