Abstract
(EN)
Disclosed is a nonaqueous electrolyte battery having excellent charge/discharge cycle characteristics, wherein internal short-circuiting caused by growth of dendrites from the negative electrode can be suppressed. Also disclosed is a solid electrolyte which is capable of improving the charge/discharge cycle characteristics of a nonaqueous electrolyte battery when used in a solid electrolyte layer of the nonaqueous electrolyte battery. Specifically disclosed are: a nonaqueous electrolyte battery comprising a positive electrode, a negative electrode and a solid electrolyte layer that is interposed between the electrodes, wherein the solid electrolyte layer has an excessive sulfur portion that contains 10% by mole or more of elemental sulfur; and a solid electrolyte for a nonaqueous electrolyte battery, which has an excessive sulfur portion that contains 10% by mole or more of elemental sulfur.
