Abstract: In various examples, a functionalized cross-linked polymer network includes a plurality of cross-linked multifunctional trione triazine groups, a plurality of disulfide groups, a plurality of cross-linked multifunctional ether groups, a plurality of cross-linked multifunctional polyether groups, or a combination thereof, a plurality of crosslinking multifunctional polyether groups, and a plurality of dangling groups, where individual cross-linked multifunctional trione triazine groups and/or cross-linked multifunctional disulfide groups and/or cross-linked multifunctional ether groups and/or cross-linked multifunctional polyether groups and individual crosslinking multifunctional polyether groups are connected by one or more covalent bond(s) and individual dangling groups may be connected to the network by a covalent bond. At least a portion of or all of the dangling groups may be halogenated. A functionalized cross-linked polymer network may be made by polymerization (e.g., Thiol-ene reach on(s)) of one or more functionalized monomer(s) and one or more multifunctional monomer(s).

Abstract: Solid-polymer electrolytes, methods of making solid-polymer electrolytes, and uses of solid-polymer electrolytes. A solid-polymer electrolyte comprises a cross-linked polymer network. A cross-linked polymer network may comprise a plurality of groups, which may be cross-linked groups, such as, for example, cross-linked difunctional polyether groups, cross-linked difunctional ionic groups, non-crosslinked groups, which may be referred to as “dangling” groups, or a combination thereof, and a plurality of cross-linked multifunctional crosslinker groups. A solid polymer electrolyte can be formed by polymerization. A solid polymer electrolyte can be formed in situ in a device. A solid polymer electrolyte can be used in devices such as, for example, batteries, supercapacitors, fuel cells, and the like.
