微型柔性超级电容器及其阵列应用于电子器件的研究

In order to obtain high-performance flexible micro-supercapacitors and arrays, a kind of flectional electrode material possessed high porosity, excellent mechanical properties and environment benign is badly in need. Molybdenum disulfide (MoS2), as a tunable porous material, can form porous composite films with conducting polymer exhibiting high conductivity and large specific surface area. The high-performance micro-supercapacitors and arrays assembled by multicomponent electrodes are able to embedded into wearable miniature electronic devices for energy storage and supply. This project focuses on simple method of deposition MoS2/multi-composite conducting polymer composites and its energy storage capacity. We will demonstrate the combination of this nanocomposites with micro/nano supercapacitors preparation technology to construct high-performance supercapacitors and arrays. The project methods and application in the micro electronic devices of high-performance micro-supercapacitors and arrays based on porous membrane electrodes are to be studied in detail. Moreover, the influence of energy storage capacity of prepared micro-supercapacitors on the whole electronic device will also be investigated. Hereby, based on the research above, we provide experimental and theoretical basis to employ the micro-supercapacitors assembled by porous nanocomposite films as energy storage component for wearable electronic devices.
