Research progress of gel solid electrolytes for supercapacitors
Abstract:As high energy storage devices, supercapacitors have been widely reserched and applied in various flexible devices due to their high charge and discharge rate and long service life. And the electrolyte as an important part of the supercapacitor, has an important influence on the performance of the device. Due to the shortcomings of traditional liquid electrolytes such as easy leakage and low ionic conductivity of inorganic solid and solid polymer electrolytes, gel polymer electrolytes with high ionic conductivity and large mechanical deformation have attracted wide attention. This paper summarizes the research progress of gel polymer solid electrolytes and their applications in supercapacitors, focuses on the classification and composition of gel polymer solid electrolytes, and discusses the latest research progress of various gel electrolytes. The important characterization and performance testing methods of electrolytes are emphasized in this paper, and the future research directions are also prospected.
Keywords: gel polymer solid electrolyte ionic conductivity supercapacitor progress
