Material and structural design of microsupercapacitors.

With the rapid development of miniaturization and miniaturization of portable electronic devices, the requirements of electronic devices are increasing for the performance of energy storage components within a certain volume. Considering the low power density and short cycle life of microbatteries, they cannot meet the requirements of rapid charge/discharge and long life of microelectronic devices. Meanwhile, microsupercapacitors (MSCs) have many advantages, such as high power density and long service life, and they meet the needs of use and development and have good prospects and progress advantages. In recent years, as new energy storage devices, MSCs have been widely studied in the design of device structure, but they are limited by many challenges such as low energy storage density, large internal resistance, improved cycle stability, and complex micropreparation technology. In this paper, the principle of MSCs and the research progress of structured electrodes were reviewed, thus providing a reference for the continuous optimization of the structure.
