Abstract: Disclosed herein are precursor solutions, gel polymer electrolytes prepared therefrom, and electrochemical devices comprising the same. In some embodiments, the gel polymer electrolyte comprises an electrolyte salt, a nonaqueous solvent, and a crosslinked polymer obtained from an Aza-Michael addition between a Michael donor with at least two primary amines and a Michael acceptor with at least three carbon-carbon double bond groups, wherein the Michael donor has a molecular weight of no greater than 600 Daltons and is fully dissolved in the precursor solution, and the Michael donor can react with the Michael acceptor via Aza-Michael addition to form a crosslinked polymer. In some embodiments, the nonaqueous solvent is free of groups reactive with lithium metal. In some embodiments, the nonaqueous solvent comprises a fluorinated ether, a fluorine-free ether or mixture thereof. In some embodiments, the electrochemical device comprising the polymer electrolyte exhibits an improved cycling performance.

Abstract: The present disclosure relates to electroactive materials that are useful for secondary battery electrode materials and the secondary battery device including thereof. Further, the disclosure relates to cathode and anode materials obtained via the polymerization of triptycene-based organic molecules having one or more arylene diimide groups attached forming a crosslinked network.
