Despite the high potential impact of aqueous battery systems, fundamental characteristics such as cost, safety, and stability make them less feasible for large-scale energy storage systems. One of the main barriers encountered in the commercialization of aqueous batteries is the development of large-scale electrodes with high reversibility, high rate capability, and extended cycle stability at low operational and maintenance costs. To overcome some of these issues, the current research work is focused on a new class of material based on phenethylammonium bismuth iodide on fluorine doped SnO-precoated glass substrate via aerosol-assisted chemical vapor deposition, a technology that is industrially competitive. The anode materials were electrochemically investigated in Zn aqueous electrolytes as a proof of concept, which presented a specific capacity of 220 mAh g at 0.4 A g with excellent stability after 50 scans and capacity retention of almost 100%.
尽管水系电池系统具有很高的潜在影响，但成本、安全性和稳定性等基本特性使其在大规模储能系统中不太可行。水系电池商业化过程中遇到的主要障碍之一是开发具有高可逆性、高倍率性能和在低运行及维护成本下具有长循环稳定性的大规模电极。为了克服其中一些问题，当前的研究工作集中在通过气溶胶辅助化学气相沉积法在氟掺杂的SnO预涂覆玻璃基板上制备基于苯乙铵铋碘化物的新型材料，这是一种具有工业竞争力的技术。作为概念验证，在锌水系电解质中对阳极材料进行了电化学研究，在0.4 A g下其比容量为220 mAh g，在50次扫描后具有出色的稳定性，容量保持率几乎为100%。
