PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery which efficiently stores lithium ions in negative electrode active material, and can thereby surely supplement loss in capacity in the negative electrode. SOLUTION: This secondary battery is equipped with a positive electrode 1 containing lithium ions, a negative electrode 2 capable of storing and emitting lithium ions, and with non-aqueous electrolyte. In this case, carbon material 18 used as active material for the negative electrode 2, a conductive metal 15 capable of forming no alloy with lithium, is deposited on the surface of the carbon material to the thickness less than 1μm, and furthermore, metal lithium 16 is deposited on the surface of the conductive metal 15. |
