摘要
铝空气电池被认为是一种有希望的清洁能源。然而,铝阳极严重的自腐蚀问题阻碍了其商业化应用。在此,我们提出了一种由4-氨基-6-羟基-2-巯基嘧啶(AHMP)和氧化锌(ZnO)组成的原始杂化添加剂来抑制碱性铝空气电池中Al-6061的自腐蚀。它诱导在阳极上形成致密的双功能膜。阳极利用率达到60%,全电池的质量容量从空白电池的879 mAh g−1提高到添加杂化添加剂后的1785 mAh g−1。令人惊讶的是,这种薄膜同时起着激活阳极的作用,提高了电池的放电电压。实验和理论计算共同揭示了这种独特的双功能界面膜的形成机制:双金属(Al, Zn)与AHMP分子上不同的吸附位点“定向桥接”。本研究探讨了混合添加剂协同效应的来源,为筛选功能化添加剂构建铝-空气电池铝/电解质界面膜提供了一种新的策略。
Synergistic construction of bifunctional interface film on anode via a novel hybrid additive for enhanced alkaline Al-air battery performance
Aluminum-air battery is considered to be a hopeful source of clean energy. However, the serious self-corrosion of Al anode hinders its commercial application. Herein, we propose an original hybrid additive consisting of 4-amino-6-hydroxy-2-mercaptopyrimidine (AHMP) and zinc oxide (ZnO) to inhibit self-corrosion of Al-6061 in alkaline Al-air battery. It induces a dense bifunctional film formed on the anode. The anode utilization rate reaches 60%, and the mass capacity of full cell increases from 879 mAh g−1 (blank) to 1785 mAh g−1 (with the hybrid additive). Surprisingly, this film simultaneously functions to activate the anode, boosting the discharge voltage of full cell. Experiments and theoretical calculations jointly reveal the mechanism formation of this unique bifunctional interface film: “site-directed bridging” of double metals (Al, Zn) to distinct adsorption sites on AHMP molecules. Our work investigates the origin of the synergistic effect for hybrid additives and provides a new strategy for screening functionalized additives to construct characteristic aluminum/electrolyte interface film for Al-air battery.
