Abstract:	The fast growing field of microsized electronic devices has urgent demand for next‐generation microscale, flexible, and lightweight energy conversion and storage devices. Among the various microdevices, microsupercapacitors (MSCs) are a promising energy storage device due to their fast rechargeability, better rate capability, long cycle life, and ultrahigh power density. The 2D graphene possesses a large surface area with flexibility, better conductivity, transparency, and high quantum capacitance that lead to an ideal energy storage material for the MSCs. Therefore, this review aims to summarize recent advances in graphene‐based MSCs. A particular emphasis is put on the various fabrication technologies for MSCs such as printing, laser, wet‐spin, and photolithography technique that are discussed elaborately. Moreover, an overview of the state‐of‐the‐art on graphene‐based electrode materials and its different composite with transition metal oxides, transition metal hydroxides, conducting polymers, transition metal chalcogenides, and MXene‐based electrode materials for MSCs are discussed and their electrochemical performances are summarized. Furthermore, this review concludes with perspectives and outlooks. [ABSTRACT FROM AUTHOR]
