Abstract:
1. A solid electrolyte battery comprising: a positive electrode; a negative electrode disposed opposite to said positive electrode; a separator disposed between said positive electrode and said negative electrode; and a solid electrolyte disposed between said positive electrode and said separator and between said separator and said negative electrode; wherein said solid electrolyte comprises a mixture of a polymer and a swelling solvent present in a ratio of from 1:5 to 1:10; wherein said separator comprises a polyolefin porous film having a thickness of from 5 μm to 15 μm and a volume porosity of from 25% to 60%; wherein the impedance in said solid electrolyte battery is greater than the impedance realized at the room temperature when the temperature of said solid electrolyte battery is from 100° C. to 160° C.; and wherein said solid electrolyte has a thickness of from 5 μm to 19 μm.
