NON-AQUEOUS ELECTROLYTE CELL

摘要

A non-aqueous electrolyte cell equipped with a negative electrode using lithium as an active material, a positive electrode, a non-aqueous electrolyte comprising a solute and an organic solvent, a separator and an outer can, characterized in that the organic solvent contains a compound having an S-O bond and a collector used as the positive electrode and a portion of the outer can in contact with the electrolyte on the side of the positive electrode are composed of a valve metal or an alloy thereof. The non-aqueous electrolyte cell exhibits excellent low-temperature characteristics and stability for an extended period of time and is excellent in cycle characteristics when it is used as a secondary cell.
