摘要

虽然传统的电解质添加剂具有高效的防腐蚀和安全性，但现有的静态添加剂吸附膜通常存在较差的电子和离子传输。本文报道了一种铝-空气电池中具有吸附-解吸特性的混合电解质添加剂。我们研究了十六烷基三甲基溴化铵（CTAB）和甘油（Gly）作为混合添加剂来防止铝阳极在碱性溶液中的腐蚀。方法采用析氢试验、电化学测量、形态分析和分子模拟等方法探讨其缓蚀解吸机理。结果表明，该材料的缓蚀效率可达75.81%。在放电过程中，添加剂也可以从铝阳极表面解吸。最佳阳极利用率、容量密度和能量密度分别提高到61.91%、1843.31 mA•h•g−1和2183.59 W•h•g−1。

Mixed electrolyte additive with adsorption–desorption properties in aluminum–air batteries

Background

Although traditional electrolyte additives promise high-efficiency corrosion protection and safety, existing static additive adsorption films typically suffer from inferior electron and ion transport. Here, we report a mixed electrolyte additive with adsorption–desorption properties in aluminum–air batteries. We examine hexadecyl trimethyl ammonium bromide (CTAB) and glycerol (Gly) as mixed additives to prevent aluminum anode corrosion in alkaline solutions.

Methods

Hydrogen evolution test, electrochemical measurements, morphological analysis, and molecular simulation are used to explore the corrosion inhibition and desorption mechanisms.

Significant findings

An efficiency of up to 75.81% can be achieved in corrosion inhibition. The additives can also be desorbed from the aluminum anode surface during discharge. The optimum anode utilization rate, capacity density, and energy density can increase to 61.91%, 1843.31 mA•h•g⁻¹, and 2183.59 W•h•g⁻¹, respective -ly.
