Title:
Nonaqueous electrolyte secondary battery
Document Type and Number:
Japanese Patent JP5928800
Kind Code:
B2
Abstract:
Provided is a nonaqueous electrolyte secondary battery in which the following are housed in a battery case: a nonaqueous electrolyte, a boron atom-containing oxalato complex compound, and an electrode assembly in which a positive electrode having a positive electrode active material and a negative electrode having a negative electrode active material are disposed facing each other. Here, a coat containing boron atoms originating from the oxalato complex compound is formed on the surface of the negative electrode active material, and the amount BM (μg/cm2) of the boron atom as measured based on inductively coupled plasma-atomic emission spectroscopic analysis and the intensity BA for a tricoordinate boron atom as measured based on x-ray absorption fine structure analysis satisfy 0.5≤BA/BM≤1.0.
