Provided is a battery capable of improving charge-discharge cycle
characteristics. The battery comprises a spirally wound electrode body in
which a cathode and an anode are spirally wound with a separator in
between. The capacity of the anode includes a capacity component by
insertion and extraction of Li and a capacity component by precipitation
and dissolution of Li metal, and is represented by the sum of them.
Moreover, the anode includes a carbon material capable of obtaining a
first peak within a range from 1580 cm.sup.-1 to 1620 cm.sup.-1 and a
second peak within a range of 1350 cm.sup.-1 to 1370 cm.sup.-1 in a Raman
spectrum analysis using argon laser light with a wavelength of 5145 nm,
and having an intensity ratio IB/IA between the first peak and the second
peak of 0.25 to 0.6, where the intensity of the first peak is IA and the
intensity of the second peak is IB. Thereby, precipitation-dissolution
efficiency of lithium metal and charge-discharge cycle characteristics
can be improved.
