Phase-Transitional Ionogel-Based Supercapacitors for a Selective Operation
Jinwoo Park, Jeong‐Yun Sun
Abstract
at 45 °C and shows a stable capacitance retention of 87.5% after 3000 cycles of test. The phase transition can switch the SCs from "operating mode" to "storage mode" when the temperature drops. A degree of self-discharge is greatly suppressed in the storage mode, storing 89.51% of charges after 24 h in self-discharge tests.
