Metal bis(malonato) borate monomers, polymers and copolymers derived therefrom, methods of making the monomers and polymers, and articles derived therefrom

摘要

Disclosed herein are novel metal bis(malonato)borate monomers and polymers formed by polymerizing the monomers. The monomers and the polymers have conductive properties, making them particularly useful in applications requiring materials with conductive properties. When the metal is lithium, the polymers are particularly well suited for use in lithium ion batteries.
