Document Type and Number:
Japanese Patent JP4803486
Kind Code:
B2
Abstract:
It is aimed at providing a nonaqueous electrolyte cell excellent in cell performance in a high-temperature environment. A nonaqueous electrolyte cell comprising a positive electrode and a negative electrode, and produced by using a nonaqueous electrolyte including at least one kind of a cyclic carbonate having a carbon-carbon pi bond and at least one kind of a cyclic organic compound having an S-O bond, characterized in that the positive electrode is constituted of a positive-electrode active material including a main component which is a fired oxide having a layered rock salt type crystal structure represented by Lim[NibM(1-b)O2] (M is one or more kinds of elements included in 1 to 16 groups excluding Ni, Li, and O; and 0<=m<=1.1), and in which the value of b is 0m[MnaNibCocO2] (0<=m<=1.1, a+b+c=1, |a-b|<=0.05, a<>0, b<>0) in which the value of c is 0<=c<1.
