PURPOSE: To provide a lithium secondary battery with high average potential of discharging and excellent safety. CONSTITUTION: This lithium secondary battery has a positive electrode 2, a negative electrode 3, a separator 4 interposed between the both and a nonaqueous electrolyte 5. The positive electrode active material consists of a material represented by Lix Tiy O4 (wherein 0<x<=2, 0<y<=3) or Lia Tib Mc O4 (wherein 0<a<=2, 0<b<=3, 0<c<=3), and M is at least one element selected from Mn, Fe, Cr, Ni, Co, Mg and B. On the other hand, the negative electrode active material consists of a material represented by Liz Fe2 O3 (wherein 0<z<=6). |
