Special Devices for Zinc-Ion Battery: Structure, Mechanism, and Application

Aqueous zinc-ion batteries (ZIBs) have received a lot of attention because of their high safety, environmental friendliness, and low cost. At the same time, special configuration ZIBs also have been widely developed to meet some special functions and applications. However, there is a lack of systematic summary on the structures, mechanisms, and applications of these ZIBs. In this review, we mainly summarize and discuss the various special configuration devices for ZIBs, such as photorechargeable ZIBs, self-charging ZIBs, stretchable ZIBs, biocompatible ZIBs, decoupling ZIBs, and micro-ZIBs. Moreover, in the last section, we highlight the importance of type and structure of the electrode material as well as the preparation of the electrode, compatibility of the electrolyte and electrode, performance modification based on the specific structure, and mechanism of special configuration ZIBs, which are expected to guide development of this field.
