基于核壳花状电极的高性能可伸缩超级电容器与光电探测器的集成
High-performance stretchable and compressible supercapacitor based on the core-shell flower structured electrode for integration with photodetectors
摘要
Abstract
The integration of energy storage devices with solar cells is a challenge to the development of wearable and flexible electronics with stable power output. A high-performance flexible asymmetric all-solid-state fiber supercapacitor was fabricated with Co3O4@Ni-Co-S and FeSe2 as the positive and negative electrodes,respectively. The as-prepared Co3O4@Ni-Co-S electrodes demonstrated outstanding volume-specific capacitance (5.0 F·cm-3 at 0.4 mA) and excellent cycling performance (83.6% after 5000 cycles) owing to their 3D core-shell micro-chrysanthemum flower and micro-snowflakes structures. Furthermore,photo-charged asymmetric supercapacitor(PSC)was prepared by using silicon solar cells for direct photo-charging. The resulting PSC could also be used to power a mini-scale flexible photodetector based on TiO2 anode and PEDOT cathode under any bending angles and under stretchable/compressible states. In addition,core-shell Co3O4@Ni-Co-S micro-chrysanthemum electrodes displayed exciting electrocatalytic hydrogen evolution reactions, showing excellent potential for the construction of high-performance flexible and wearable energy devices.关键词
