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.
Abstract: 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.
