Abstract:
A polymer that can be used as a binder for sulfur-based cathodes in lithium batteries is disclosed. The polymer includes in its composition olefinic groups capable of reaction with and entrapment of polysulfide species. Beneficial effects include reductions in capacity loss and/or ionic resistance gain.
