LITHIUM ION SECONDARY BATTERY

Document Type and Number:

Japanese Patent JP2017152362

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery which is superior in rapid charging at a low temperature.SOLUTION: A lithium ion secondary battery comprises: a positive electrode having a positive electrode active material layer; a negative electrode; and an electrolytic solution. The positive electrode active material layer includes, as a positive electrode active material, Li(M)(PO)(where M=VO or V, 0.9≤a≤3.3, 0.9≤b≤2.2, and 0.9≤c≤3.3), and it further includes a fluorine compound at 1-300 ppm to a weight of the positive electrode active material layer in terms of fluorine.SELECTED DRAWING: Figure 1
