1. An electrolyte for an electrochemical battery, the electrolyte comprising:
a carbonate solvent;
a salt dissolved in the carbonate solvent; and
a thioamide compound dissolved in the carbonate solvent,
the thioamide compound being thioformamide.
 
10. A method of fabricating an electrolyte for an electrochemical battery, the method comprising:
providing a carbonate solvent;
dissolving a salt in the carbonate solvent; and
dissolving a thioamide compound in the carbonate solvent to give the electrolyte,
the thioamide compound being thioformamide.
 
17. An electrolyte for an electrochemical battery, the electrolyte comprising:
a carbonate solvent;
a salt dissolved in the carbonate solvent; and
a thioamide compound dissolved in the carbonate solvent,
the thioamide compound being thioformamide,
the thioamide compound being present in the carbonate solvent at a concentration in a range of from 1 millimolar (mM) to 50 mM,
the salt being lithium hexafluorophosphate (LiPF6) or lithium tetrafluoroborate (LiBF4),
the salt being present in the carbonate solvent at a concentration in a range of from 0.5 molar (M) to 5 M, and
the carbonate solvent being ethylene carbonate (EC), ethyl methyl carbonate (EMC), or dimethyl carbonate (DMC).
