Non-aqueous electrolyte cell, electrode stabilizing agent, phosphazene derivative and method of producing the same

摘要

A non-aqueous electrolyte cell comprises a positive electrode, a negative electrode and a non-aqueous electrolyte containing a support salt. The non-aqueous electrolyte further comprises a phosphazene derivative. The phosphazene derivative having a specified structure functions as an electrode stabilizing agent or a non-combustion agent.
