Reversible transformation between solid and liquid states of Na2S2O3·5H2O leads to supercapacitor electrolytes with low volatilization and low self-discharge

In this study, we used Na 2 S 2 O 3 ·5H 2 O as the electrolyte for aqueous supercapacitors. Na 2 S 2 O 3 ·5H 2 O in supercapacitors as an aqueous electrolyte can reduce the volatilization of the electrolyte and the self-discharge rate of the supercapacitor.
