NON-AQUEOUS ELECTROLYTE PRIMARY CELL AND ADDITIVE FOR NON-AQUEOUS ELECTROLYTE OF THE CELL

摘要

A non-aqueous electrolyte primary cell having a positive electrode, a negative electrode and a non-aqueous electrolyte containing a supporting electrolyte, characterized in that the non-aqueous electrolyte contains a phosphazene derivative and/or an isomer of a phosphazene derivative. The non-aqueous electrolyte primary cell exhibits improved safety while retaining cell characteristics.
