Open the CIPO recordAbstract From the Canadian patent
A totally solid polymer electrolyte composition with high ionic conductivity and enhanced mechanical properties. This electrolyte composition is produced by polymerizing a monomer composition comprising a molten quaternary ammonium salt having a polymerizable functional group introduced therein and a charge transfer ion source in the presence of a polymeric reinforcing material. The polymeric reinforcing material can be formed into a composite of polymer blend morphology by dissolving the monomer composition and the reinforcing material in an appropriate organic solvent and polymerizing the solution. Alternatively, the composite can be obtained by impregnating a porous sheet or …

Why it's free to use
- Filed March 15, 2004 and granted August 6, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 15, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 15, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
