Storage performance of large-capacitance power supercapacitor

doi:10.19799/j.cnki.2095-4239.2020.0247

Abstract

Abstract:

The charge storage capacity of supercapacitors is affected by many factors. A study of the voltage holding ability of commercial large-capacitance power supercapacitors is systematically studied from five aspects: charging current, charging voltage, constant voltage time, storage temperature, and the electrolyte system. The results indicate that lower charging current, lower charging voltage, lower ambient temperature, and longer constant voltage time are conducive to charge storage and improved monomer voltage retention capability. When the electrolyte salt is fixed, specifically tetraethylammonium tetrafluoroborate (TEA-BF₄), the solvent with the best voltage retention ability was propylene carbonate (PC). With a fixed solvent (PC) and concentration of electrolyte, the TEA-BF₄ salt showed better voltage retention than spiro-(1,1′)-bipyrrolidinium tetrafluoroborate (SBP-BF₄).

Key words: supercapacitor, storage performance, self-discharge, voltage retention capability, voltage, temperature
