Abstract
A polymer formed from a first monomer of vinylene carbonate and at least one second monomer different form the first monomer that does not contain a glycidyl group, wherein the molar ratio of the first monomer to the second monomer is from 4:1 to 99:1. The polymer, preferably the copolymer, dissolves metal salts and the composition of the copolymer and metal salt may have an ionic conductivity greater than 0.01 mS/cm. The polymer is suitable for use in various components of solid state batteries.
Claims16
A copolymer, comprising as copolymerized units:
- a vinylene carbonate compound as a first monomer;
- and
- at least one additional monomer different from the first monomer and copolymerizable with the first monomer, with the proviso that the at least one additional monomer does not comprise a glycidyl group;
- wherein a molar ratio of the first monomer to the at least one additional monomer is from 4:1 to 99:1.
