非水電解質二次電池およびこの製造方法
Document Type and Number:
Japanese Patent JP4147448
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a long-life non-aqueous electrolyte secondary battery free of the risk that the discharge capacity in the initial period drops and showing a less deterioration in the capacity during the charge-discharge cycle. SOLUTION: The electrolyte of this non-aqueous electrolyte secondary battery contains 1,4,7-trioxonin expressed by Formula (1) and/or its derivative....(1) This allows formation of a protection film in good workmanship on the surface of a negative electrode active material, which suppresses decomposition of the non-aqueous electrolyte on the surface of the negative electrode active material, and as a result, the intended secondary battery of long lifetime showing a less deterioration in the capacity during the chargedischarge cycle can be achieved.
