Abstract [English] Electrolytes that include one or more salts, one or more acetamide-based solvents, and optionally, one or more non-acetamide-based solvents. In some embodiments, disclosed electrolytes can be used in electrochemical devices, such as alkaline-metal-based (e.g., lithium-based) secondary battery cells, among others. Also disclosed are electrochemical devices that incorporate disclosed electrolytes. [French] La présente invention concerne des électrolytes qui comprennent un ou plusieurs sels, un ou plusieurs solvants à base d'acétamide, et éventuellement un ou plusieurs solvants qui ne sont pas à base d'acétamide. Dans certains modes de réalisation, les électrolytes divulgués peuvent être utilisés dans des dispositifs électrochimiques, tels que des cellules de batterie secondaire à base de métal alcalin (par exemple, à base de lithium), entre autres. Sont également divulgués des dispositifs électrochimiques qui incorporent les électrolytes divulgués.
