Realizing Stretchable Aqueous Zn–Based Batteries by Material and Structural Designs

Abstract

The increasing demands on stretchable power supply for wearable electronics accelerate the development of stretchable batteries. Zn-based batteries are promising to be applied in wearable electronics due to their outstanding performance, intrinsic safety, low cost, and environmental friendliness. Recently, stretchable Zn-based batteries are designed to demonstrate the capability of delivering excellent electrochemical performance, meanwhile maintaining their mechanical stability. This review provides an overview of different strategies and designs to realize stretchability in different Zn-based battery components. The general strategies to realize stretchability are first introduced, followed by the specific designs on the cathode, anode, and electrolytes of Zn batteries. Moreover, current issues and possible strategies are also highlighted.

“…[7,13,33,34] In addition, current literature lacks detailed summary on some important aspects, such as the criteria of selecting right materials and strategies as well as novel functionalities for stretchable AZIBs. [1,35,36] Here, we would like to provide a thorough overview of the state-of-the-art achievements of stretchable AZ-IBs for wearable electronics. Wearable electronics are a broad family, including power consumption modules (e.g., sensors, transistors, displays), switches, interconnection wires, and power supplies.…”
