Electrolyte compositions, methods of making same, uses thereof

Abstract

Electrolyte compositions comprising one or more ion conducting salt(s) and one or more ammonium salt(s), such as, for example, asymmetric ammonium salt(s) or the like, which may, independently, be a quaternary ammonium salt. In various examples, the ammonium salt(s) independently comprise cations(s) chosen from primary ammonium cations, secondary ammonium cations, tertiary ammonium cations, quaternary ammonium cations, and the like, and any combination thereof. In various examples, an electrolyte composition further comprises one or more additional salt(s), which may, independently, be an ion-conducting salt. In various examples, an anode comprising an SEI layer is formed by contacting an anode, such as, for example, a metal anode or the like, with one or more electrolyte composition(s). In various examples, an electrochemical device, such as, for example, a battery, a supercapacitor, a fuel cell, an electrolyzer, an electrolytic cell, or the like comprises one or more composition(s) and/or one or more anode(s).
