Abstract
A lithium ion battery includes: a negative electrode in which a state of charge at a potential to be 0.1 V with respect to a lithium potential is 60% or more; and a positive electrode containing a lithium-containing composite metal oxide, and a capacity ratio of the positive electrode and the negative electrode (negative electrode capacity/positive electrode capacity) is 1 or more and less than 1.2. In the lithium ion battery described above, the lithium-containing composite metal oxide contains layered lithium nickel manganese cobalt composite oxide (NMC) and spinel lithium manganese oxide (sp-Mn).
