Highly Conductive Polysiloxane Polymers


Robert West, Richard Hooper, David Moline

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing an effective method for producing highly conductive materials for use in lithium-based batteries.
OVERVIEWLithium batteries deliver high levels of power per unit weight, making them useful for applications in computers and potentially for electrically powered automobiles. However, most existing lithium batteries contain a liquid such as polyethylene oxide that acts as an electrolyte. If these batteries were used in automobiles, a leak could result if an accident were to occur. An improved solid electrolyte conductor for use with lithium-based batteries is needed.
THE INVENTIONUW–Madison researchers have developed solid polysiloxane polymers with multiple oligooxyethylene side chains per silicon. These materials are highly conductive, which makes them commercially competitive and useful for industrial applications. The researchers also developed effective methods for producing these compounds as well as intermediate compounds that are useful in making the polysiloxane polymers.
  • Automotive lithium-based batteries
  • Compounds are solid and highly conductive.
