Three solid electrolyte interphases of aqueous zinc batteries

Abstract

With the increasing demand for enhanced safety performance of rechargeable batteries, water-based zinc-ion batteries have witnessed rapid development due to their exceptional safety characteristics. And, zinc batteries have been widely used in a diverse of various fields such as electric vehicles and electric bicycles. However, the dendrite issue and limited cycle life of the negative electrode pose significant challenges that hinder further advancements in this technology, which greatly limits the development of zinc batteries. For this reason, extensive research has been conducted on various solid electrolyte interphases related to the battery anode. By comprehensively understanding and comparing three materials of solid electrolyte interphase (SEI) utilizing similar controlled negative ion techniques, it can validate the accuracy of this theoretical approach. The utilization of these three materials results in a substantial improvement in battery performance compared to the original battery, particularly in terms of service life; however, each material also exhibits distinct advantages and drawbacks.
