摘要

本文系统地研究了在镁空气电池中使用乙醇和络合剂混合物的新策略。乙醇的存在促进了放电膜中氧化物含量较高的致密内层的形成，从而显著提高了利用效率。在混合电解质中放电时，镁阳极的最高利用效率从 53.6% 提高到 85.7%，放电电位降低了 300 mV。在含乙醇和 5-磺基水杨酸的溶液中，S 类物质在金属表面的吸附/沉积得到了证实，从而抑制了富氢氧化物外层的生长。

A novel insight into the enhanced electrochemical performance of Mg-air battery in mixed aqueous and organic electrolytes

A new strategy of utilizing mixtures of ethanol and complexing agents on Mg-air battery is investigated systematically. The presence of ethanol promotes formation of a dense inner layer with a high portion of oxide in the discharge film, leading to significantly enhanced utilization efficiency. The highest utilization efficiency of Mg anode has been increased from 53.6 % to 85.7 % and the discharge potential is decreased 300 mV, when discharges in mixed electrolyte. The adsorption/deposition of S-like species on metal surface is evidenced in ethanol and 5-sulfosalicylate acid containing solution, resulting in inhibition of the hydroxide-rich outer layer growth.
