▎ 摘　　要

The emerging flexible electronic devices have stimulated the development of flexible batteries, in which flexible electrodes are indispensable components. Graphene, known for its excellent electrical conductivity and mechanical stability, can be used as an ideal flexible substrate. Recently, many efforts have been devoted to graphene-based electrodes for flexible batteries. Herein, this review summarizes recent advances in the development of graphene-based electrodes for various flexible batteries, including metal-ion batteries (ions of Li, Na, Zn, Al, etc.), lithium-sulfur batteries, and metal-air batteries (Li- and Zn-air batteries). Besides, major challenges and future developments of flexible batteries are also discussed.
