Abstract
Disclosed herein are molecular ionic composite (MIC) polymer electrolytes. The MIC electrolytes described may be formulated to provide enhanced mechanical properties, improved ionic transport, and stable electrochemical performance across a broad temperature range. The compositions and methods presented are adaptable and may be tailored for various battery applications, including but not limited to solid-state lithium batteries or high-voltage lithium batteries.
Claims20
A composite electrolyte comprising:
- a sulfonated polyaramid;
- an ionic liquid;
- a dopant comprising an alkali metal salt;
- and
- an alkali metal salt additive that is different from the dopant and comprises an alkali metal phosphate salt, an alkali metal hexafluorophosphate salt, an alkali metal borate salt, an alkali metal tetrafluoroborate salt, or a combination thereof.
