Non-aqueous electrolyte cell, electrolyte stabilizing agent, and phosphazene derivative and method for preparation thereof

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.
