Non-aqueous electrolyte secondary battery and method for producing the same
For providing a non-aqueous electrolyte secondary battery having excellent storage characteristics when stored in the charged state under a high temperature condition, the non-aqueous electrolyte or the negative electrode is made to contain divinylethylene carbonate, thereby to form a film derived from divinylethylene carbonate on the surface of the negative electrode material.
