Aluminum-air batteries (AABs), due to their low cost and high specific capacity, receive much attention nowadays. Nonetheless, a vital problem curbing wide application of AABs is corrosion of the aluminum (Al) anode, which is triggered by hydrogen evolution reaction (HER). Therefore, this work tackles the problem of anode corrosion in an alkaline Al-air flow battery (AAFB) by implementing a dual-electrolyte system. The battery configuration consists of an Al anode | anolyte | anion exchange membrane | catholyte | air cathode. The anolytes in this work are ethylene glycol/ethanol solutions (0, 5, 10, 20, and 30%) v/v containing 3 M potassium hydroxide (KOH). A polymer gel electrolyte (Carbopol^® 940) is employed as the catholyte. The corrosion of an Al electrode in the anolytes is duly examined. It is significant that when the ratio of ethylene glycol exceeds 5% v/v, this negatively affects the dissolution process and suppresses Al corrosion. Furthermore, the battery using the anolyte with 5% v/v ethylene glycol, at a discharge current density of 5 mA/cm², demonstrates peak power of 3.75 mW/cm². The battery also exhibits the highest specific discharge capacity of 2,100 mAh/g_Al (70% utilization of Al) at a discharge current density of 2.5 mA/cm². In general, the dual-electrolyte system affirms its effectiveness in controlling anodic corrosion, quelling passivation of the Al surface in the alkaline AABs and boosting discharge capacity. KOH in ethylene glycol/ethanol solution is a promising anolyte being more environmentally friendly, less toxic and providing favorable electrochemical performance.

铝空气电池（AAB）由于其低成本和高比容量，在当今受到了广泛的关注。但是，限制AAB广泛应用的一个至关重要的问题是铝（Al）阳极的腐蚀，这是由析氢反应（HER）引发的。因此，这项工作通过实施双电解质系统解决了碱性铝空气流通电池（AAFB）中阳极腐蚀的问题。电池配置包括一个铝阳极。阳极电解液| 阴离子交换膜| 阴极液| 空气阴极。这项工作中的阳极电解液是v / v的乙二醇/乙醇溶液（0％，5％，10％，20％和30％），含有3 M氢氧化钾（KOH）。的聚合物凝胶电解质（卡波普^®940）用作阴极电解液。适当检查阳极电解液中铝电极的腐蚀情况。重要的是，当乙二醇的比例超过5％v / v时，这会对溶解过程产生负面影响并抑制Al腐蚀。此外，电池使用具有5％V / V乙二醇阳极电解液，在5毫安/平方厘米的放电电流密度²，展示的3.75毫瓦/平方厘米的峰值功率²。该电池还具有最高的比放电容量，即2,100 mAh / g_铝（Al的利用率为70％），放电电流密度为2.5 mA / cm ²。通常，双电解质系统肯定了其在控制阳极腐蚀，抑制碱性AAB中的Al表面钝化以及提高放电容量方面的有效性。乙二醇/乙醇溶液中的KOH是一种很有前途的阳极电解液，它对环境更友好，毒性更小并且具有良好的电化学性能。
