Abstract
Official abstract text for this publication.
A battery having an anode, a soft-solid electrolyte, and a cathode. The soft-solid electrolyte includes a polymer soft-solid material formed from polymer combined with a solvent such as butylene carbonate, butyl sulfoxide, n-methyl-2-pyrrolidone, or γ-caprolactone.
First claim
Opening claim text (preview).
We claim: 1. A battery, comprising: an anode; a cathode comprising a lithium-containing electrode active material having a spinel structure or a layered oxide structure; and an electrolyte film including a lithium salt and a polymer soft-solid material, the polymer soft-solid material comprising a solvent selected from the group consisting of butylene carbonate, butyl sulfoxide, N-methyl-2-pyrrolidone, and γ-caprolactone and comprising an ethylene oxide polymer at a concentration of at least 15% of the total weight of the electrolyte film. 2. The battery of claim 1 , wherein the solvent comprises butylene carbonate. 3. The battery of claim 1 , wherein the solvent comprises butyl sulfoxide. 4. The battery of claim 1 , wherein the solvent comprises N-methyl-2-pyrrolidone. 5. The battery of claim 1 , wherein the solvent comprises γ-caprolactone. 6. The battery of claim 2 , wherein the lithium salt comprises lithium bis(trifluoromethanesulfonyl)imide. 7. The battery of claim 1 , wherein the solvent comprises butylene carbonate and about 20 molar percent lithium bis(trifluoromethanesulfonyl)imide. 8. The battery of claim 4 , wherein the lithium salt comprises lithium bis(trifluoromethanesulfonyl)imide. 9. The battery of claim 1 , wherein the solvent comprises N-methyl-2-pyrrolidone and about 20 molar percent lithium bis(trifluoromethanesulfonyl)imide. 10. The battery of claim 2 , wherein the lithium salt comprises lithium tetrafluoroborate. 11. The battery of claim 1 , wherein the solvent comprises butylene carbonate and about 20 molar percent lithium tetrafluoroborate. 12. The battery of claim 3 , wherein the lithium salt comprises lithium tetrafluoroborate. 13. The battery of claim 1 , wherein the solvent comprises butyl sulfoxide and about 20 molar percent lithium tetrafluoroborate.
