    Abstract: Provided is a lithium secondary cell of 5V class having a positive electrode operating voltage of 4.5V or higher with respect to metallic lithium; the lithium secondary cell has high energy density, inhibits degradation of the electrolytic solution that comes in contact with the positive electrode and the negative electrode, and has particularly long cell life when used under high-temperature environments. The positive electrode contains, as the positive electrode active substance, a predetermined lithium-manganese oxide complex; the negative electrode contains, as the negative electrode active substance, graphite, of which surface is coated by low-crystallinity carbon; and the electrolytic solution contains one or more high-oxidation-potential solvents selected from propylene carbonate, butyl ene carbonate, 4-fluoro-1,3-dioxolan-2-one, and 4,5-difluoro-1,3-dioxolan-2-one within a range of 5 to 60 vol % of the solvent and one or two low-viscosity solvents selected from dimethyl carbonate and fluorinated cyclic ether.
