Abstract

The present invention relates to a non-aqueous electrolyte secondary battery () which includes: a positive electrode (); a negative electrode (); a non-aqueous electrolyte containing a non-aqueous solvent; an outer package () receiving the positive electrode (), the negative electrode (), and the non-aqueous electrolyte; and a current interrupt valve () which interrupts a current in response to an increase in pressure inside the outer package (). The positive electrode () contains a carbonate compound, the non-aqueous solvent contains a fluorinated cyclic carbonate and a fluorinated chain ester, and the total content of the fluorinated cyclic carbonate and the fluorinated chain ester is with respect to the total volume of the non-aqueous solvent, 50 percent by volume or more.
