Abstract
The present disclosure provides electrolytes for an electrochemical device. In some embodiments, these electrolytes are Mg salts comprising 10-vertex or 12-vertex carborane anions. The present disclosure also provides processes for preparing electrolytes for an electrochemical device. In some embodiments, the process comprises reduction of a reactive cation complexed with a 10-vertex or 12-vertex carborane or 12-vertex borate anion to form metal carborane or borate electrolytes. In some embodiments, the process comprises comproportionating a Mg+2 10-vertex or 12-vertex carborane salt to form a Mg+1 electrolyte comprising a 10-vertex or 12-vertex carborane. The present disclosure further provides electrochemical devices comprising the electrolytes disclosed herein. In some embodiments, the electrochemical device comprises an electrolyte that is stable at an electrical potential greater than 4 V vs Mg0/+2. Also provided herein are heterocyctes bearing the 10, 11, and 12 vertex carborane anions for application as catalyst and battery electrolyte components. The methods of making are also disclosed.
