ABSTRACT:
A non-aqueous electrolyte secondary battery according to the present invention is characterized by including a non-aqueous electrolyte which contains at least one of vinylene carbonate derivatives at a concentration of 1 wt % or less and at least one of cyclic sulfates at a concentration of 2 wt % or less. According to the present invention, a non-aqueous electrolyte secondary battery having excellent discharge characteristics at a low temperature can be obtained.
