Flexible Al-air batteries have great potential in the field of wearable electronic devices. However, how to reduce the thickness of the battery and improve their applicability in wearable applications is still an unresolved thorny problem. Therefore, this article focuses on the strategies to minimize the thickness of the solid electrolyte for flexible Al-air batteries. In this paper, an innovative aerosol jet printing method is used to prepare the ultrathin neutral electrolyte with a thickness of 18.3-74.5 μm. This study discusses the influence of the thickness and ion concentration on the conductance of the electrolyte in detail. The ultrathin electrolyte has been applied to the flexible Al-air battery, and the battery performance has been explored. The cell pack composed of single cells is light and thin, and can successfully drive small electrical equipment. This study provided new ideas for the preparation of ultrathin electrolyte for flexible energy products.
柔性铝空气电池在可穿戴电子设备领域具有巨大潜力。然而，如何减小电池厚度并提高其在可穿戴应用中的适用性仍是一个尚未解决的棘手问题。因此，本文重点关注使柔性铝空气电池的固体电解质厚度最小化的策略。在本文中，采用一种创新的气溶胶喷射印刷方法制备了厚度为18.3 - 74.5μm的超薄中性电解质。本研究详细讨论了厚度和离子浓度对电解质电导率的影响。该超薄电解质已应用于柔性铝空气电池，并对电池性能进行了探索。由单电池组成的电池组轻薄，能够成功驱动小型电气设备。本研究为柔性能源产品超薄电解质的制备提供了新思路。
