Research Progress in Electrode Materials and Devices of Flexible Supercapacitors
Supercapacitor (SC),also called electrochemical capacitor,which has higher power density and longer cycling life than lithium ion battery as well as higher energy density than dielectric capacitor,is a kind of promising energy storage device.The different kinds of flexible and wearable electronic devices are emerging with consumers' increasing requirements for electronic devices.Flexible SC,which is a kind of portable energy storage device,has attracted much attention.The two-dimensional planar-structure and one-dimensional fiber-shaped SCs have been developed rapidly with the flexible electronic devices advancing.In this review,the energy storage mechanism of SCs,the diverse performance metrics and evaluation for SCs as a foundation are first introduced to understand different research approaches.Then,the current state-of-the-art progress in devices' structure design and electrode materials fabrication of the flexible two-dimensional planar-structure and one-dimensional fiber-shaped SCs are summarized.Last,perspectives on the future development of flexible SCs and highlighted key technical challenges with hope of stimulating further research progress are presented.
