To date, the exploration of zwitterionic application is confined to the function of electrolyte's additives to improve the properties of the electrolytes. However, reports on the unique properties of zwitterions, namely the anti-polyelectrolyte effect (APE), as the regulators of the electrochemical stability windows (ESWs) of the zwitterionic electrolytes are scarce. Herein, a zwitterionic electrolyte system is designed and study the relationship between the APE and the ESWs of the zwitterionic electrolytes. The hydrogen/oxygen evolution in the zwitterionic electrolytes is significantly inhibi...
