Abstract

A lithium-ion secondary cell according to the present invention is provided with a positive electrode and a negative electrode. The positive electrode contains a lithium-manganese composite oxide partially substituted by magnesium as a positive electrode active material. The negative electrode contains a graphite coated with amorphous carbon as a negative electrode active material, a carbon black-based conductive aid and a fluororesin-based binding agent.
