Title:
A valuation method of a nonaqueous electrolyte rechargeable battery
Document Type and Number:
Japanese Patent JP5915083
Kind Code:
B2
Abstract:
A non-aqueous electrolyte secondary battery according to the present invention includes a positive electrode, a negative electrode, and a non-aqueous electrolyte solution. The negative electrode includes a coating derived from lithium bis(oxalate)borate. Assuming that an intensity of a peak attributable to a three-coordinate structure of the coating measured by an XAFS method is represented by ± and an intensity of a peak attributable to a four-coordinate structure of the coating measured by the XAFS method is represented by ², the coating formed on the surface of the negative electrode satisfies a condition of ±/(±+²) ‰¥ 0.4. Accordingly, it is possible to provide a non-aqueous electrolyte secondary battery capable of reliably obtaining the effect due to the formation of a coating.
