Title:
非水電解質二次電池
Document Type and Number:
Japanese Patent JP7122653
Kind Code:
B2
Abstract:
A non-aqueous electrolyte secondary battery including a positive electrode, a separator, a negative electrode facing the positive electrode with the separator interposed therebetween, and an electrolytic solution containing a solvent and an electrolyte. The positive electrode includes a positive electrode material containing a lithium-nickel composite oxide represented by LiaNibM1−bO2, where M represents at least one selected from the group consisting of Na, Mg, Sc, Y, Mn, Fe, Co, Ni, Cu, Zn, Al, Cr, Pb, Sb and B, 0.95≤a≤1.2, and 0.8≤b≤1. The electrolytic solution contains an ester compound C of an alcohol compound A and a carboxylic acid compound B, and contains at least one of the alcohol compound A and the carboxylic acid compound B in an amount of 15 ppm or more, relative to a mass of the electrolytic solution.
