Abstract

Abstract Flexible Zn‐based batteries are regarded as promising alternatives to flexible lithium‐ion batteries for wearable electronics owing to the natural advantages of zinc, such as environmental friendliness and low cost. In the past few years, flexible Zn‐based batteries have been studied intensively and exciting achievements have been obtained in this field. However, the development of flexible Zn‐based batteries is still at an early stage. The challenges of developing flexible lithium‐ion batteries are presented here. Then, a brief overview of recent progress in flexible zinc secondary batteries from the perspective of advanced materials and some issues that remain to be addressed are discussed.
