An enhanced-performance Al-air battery optimizing the alkaline electrolyte with a strong Lewis acid ZnCl2
Al-air batteries are regarded as the potential energy conversion systems due to the ultra-high theoretical specific capacity of 2980 mAh/g and specific energy of 8100 mWh/g for Al anodes. However, the anodic self-corrosion has severely limited the energy efficiency, which induces a great challenge to the commercial penetration of Al-air batteries. Here, we present an alkaline electrolyte optimization with a single inorganic Zn-compound, where a strong Lewis acid ZnCl2 has the best modification effect for Al-air battery compared with ZnO and ZnCO3. The results demonstrate that the inhibition efficiency of Al anode is up to 83.03% under the adsorption of strong Lewis acid groups on the Zn protective film. The high specific capacity of 2322.91 mAh/g and specific energy of 2457.02 mWh/g for Al-air battery are obtained at the galvanostatic condition of 20 mA/cm2, and the anode efficiency is enhanced to 77.95% after ZnCl2 optimization. Moreover, the optimization mechanism is revealed, which provides a technical basis for the application of the enhanced-performance Al-air batteries in the fields of energy conversion and power supply.
期刊介绍：
Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
