Recent Development of Integrated Systems of Microsupercapacitors

Development of wearable and portable electronics promotes the miniaturization of energy storage devices. Microsupercapacitor (MSC) featuring in fast charging and discharging rates, long cycle life, and high-power density stands out from miniaturized energy storage devices, particularly for its small size and adjustable structure which is easily processed to integrate with other on-chip electronics. In this review, we systematically analyzed the MSC integration with other electronics from the perspective of structures and functions. At the beginning, we briefly introduced typical MSCs with unique properties. Subsequently, applications and integrations of MSCs with energy-consuming or energy-generating electronics were highlighted. Furthermore, compatible materials and designed structure of the all-in-one device were also depicted. Finally, challenges and future development of MSC-integrated systems were put forward.
