Abstract
This invention is directed to novel allyl carbonates and to solid electrolytes containing a solid matrix having incorporated therein allyl carbonates. The solid matrix is used in an electrolytic cell.
Claims17
A single phase, solid, solvent- containing electrolyte which comprises:
- a solid polymeric matrix;
- an inorganic ion salt;
- and
- a solvent;
- wherein said solid polymeric matrix is obtained by polymerizing an allyl carbonate monomer represented by Formula I:
- CH.sub.2 .dbd.CHCH.sub.2 R I
- where R is selected from the group consisting of aliphatic carbonates having the Formulae II and III:
- --[OC(O)].sub.a OR.sub.1 II
- and
- [OC(O)OR.sub.2 ].sub.b OC(O)OR.sub.1 III
- where R.sub.1 is independently selected from the group consisting of alkyl of from 1 to 4 carbon atoms, and allyl, R.sub.2 is an alkylene group of 2 to 4 carbon atoms, a is an integer of 1 or 2, and b is an integer from 1 to 4.
