Abstract
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.
Claims20
A battery, comprising:
- an anode;
- a cathode comprising an electrode active material;
- 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.
