Abstract
In this non-aqueous electrolyte secondary battery, a positive electrode includes a lithium transition metal composite oxide that contains Ni at 85 mol % or more with respect to the total number of moles of metal elements excluding Li, and a negative electrode includes graphite particles having an internal porosity of 1-5%. The N/P ratio is 1.00-1.05, where P is the charging capacity of the positive electrode, and N is the charging capacity of the negative electrode.
