How the potential window of aqueous electrolytes can be extended beyond 1.23V in asymmetric supercapacitor cells without electrolysis of electrolyte?

Potential window offered by aqueous electrolytes is 1.23 V, which is due to the fact that beyond 1.23 V the aqueous electrolytes will undergo electrolysis (common in symmetric supercapacitors)....
