Abstract

Secondary zinc-air batteries (ZAB) are promising sustainable energy storage systems, but their practical implementation has been hindered by a focus on materials, electrode/electrolyte design and formulations that do not translate into an efficient energy storage device. The prevailing cell design features an oversized zinc anode and an unbalanced electrolyte. As a result, the depth of discharge (DoD) of the zinc anode is typically low (<10%) and the durability of tests usually is limited to 500 h. This study focuses on evaluating the electrochemical impact of different cell designs for zinc-air batteries (ZABs) and highlights the critical role of positioning an electrolyte reservoir in close proximity to the zinc anode where a lifetime of up to 4000 h have been obtained. Our tests also involve high utilization of the zinc anode, ranging from 17.5% to 70.0% of the depth of discharge (DoD), equivalent to 136–546 mAh/g_Zn.

电池设计对二次锌空气电池耐久性的影响

二次锌空气电池(ZAB)是一种很有前途的可持续能源存储系统，但它们的实际实施受到了材料、电极/电解质设计和配方的阻碍，这些材料、电极/电解质设计和配方不能转化为有效的能量存储设备。普遍的电池设计特点是一个超大的锌阳极和不平衡的电解质。因此，锌阳极的放电深度(DoD)通常很低(<10%)，测试的耐久性通常限制在500小时。本研究侧重于评估锌空气电池(ZABs)不同电池设计的电化学影响，并强调在锌阳极附近放置电解质储液池的关键作用，该储液池的使用寿命可达4000小时。我们的测试还涉及锌阳极的高利用率，范围为放电深度(DoD)的17.5%至70.0%，相当于136-546 mAh/gZn。

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.
