ABSTRACT:
Charge-discharge cycle performance is improved in a lithium secondary battery including a negative electrode containing a negative electrode active material having silicon as its main component, provided on a surface of a current collector, a positive electrode containing a positive electrode active material, and a non-aqueous electrolyte. The positive electrode active material is a lithium transition metal oxide containing Li and Co and having a layered structure, and further containing a group IVA element of the periodic table, such as Zr, Ti, or Tf, and a group IIA element of the periodic table, such as Mg.
