Abstract
The invention relates to an incombustible separator for a non-aqueous electrolyte cell in which the separator itself does not burn even if the temperature inside the cell becomes high, and more particularly to a separator for a non-aqueous electrolyte cell made of a microporous film formed by a phosphazene derivative and/or an isomer of a phosphazene derivative to a polymer.
