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.

Solid state batteries

A safe, thin and highly conductive solid-state polymer separator for lithium-ion batteries. The separator may be deployed in a battery which lacks solvent and allows lithium ions to pass through channels via the polymerized structure. The lithium conductive polymers may be formed through free radical polymerization and may comprise a lithium conductive polymer having a polymerized carbonate solvent between iterative spacers, a lithium conductive material, and a reinforcing additive. Optionally, an interface coating may reside on one or more sides of the separator to ensure long-term operation. By utilizing such a separator in a solid-state lithium battery, cell assembly may be simplified, shrinkage may be decreased and safety may be increased. Various methods of manufacturing the solid-state polymer separator for lithium-ion batteries are disclosed.

Solid-state polymer separator for lithium-ion batteries

An assembly of lithium-based solid anodes to be formed into a lithium-ion battery. The anodes are formed with a fibrous ceramic or polymer framework having open spaces and an active surface material having lithiophilic properties. Open spaces within the fibrous framework and lithiophilic coatings deposited upon the surface of the fibrous framework allow for the free transport of solid lithium-ions within the anodes. In solid-state, lithium batteries can achieve higher capacity per weight, charge faster, and be more durable to extreme handling and temperature. A method for manufacturing a solid-state lithium battery having such an anode.
