Outline of Final Research Achievements |
There remains a safety issue that should be solved in ithium ion batteries, because they contain flammable liquid electrolytes. In this study, we developed novel safe and reliable polymer electrolytes applicable to lithium ion batteries. We synthesized some soft polymers such as polycarbosilanes, polysiloxanes, and poly(vinyl ether)s having 5-membered cyclic carbonate sturucture, which was similar to that of a component of usual liquid electrolytes. We found that these polymers showed high ionic conductivity with addition of lithium sulfonylimide salts.
