Method of manufacturing a lithium battery

A method of manufacturing a battery comprising the steps of:

• assembling a battery which includes a cathode using a lithium metal as an active material, an anode using manganese dioxide as a main component of an active material, and an electrolyte including an inorganic electrolyte dissolved in a nonaqueous solvent containing at least propylene carbonate;
• and
• predischarging said battery by using a pulse current which has a cycle of about 0.1 to about 2 seconds and which includes a discharge current and a charge current, wherein the amount of the discharged capacity during said predischarging step is from about 1.0 to about 2.0% of a total discharge capacity of the battery.

• and
• predischarging the battery by using a pulse current having a cycle of about 0.1 to about 2 seconds, which includes a discharge charge current having a current density of about 5 to 10 mA/cm.sup.2, and a charge current having a current density of about 2 mA/cm.sup.2 or less, wherein an amount of a discharged capacity which is predischarged by means of the discharge current is from about 1.0 to about 2.0% of a total discharge capacity, and an amount of a charged capacity which is charged by means of the charge current is not more than about 0.5% of the total discharge capacity, so that a net amount of the discharged capacity during said predischarging step is from about 0.5% to about 2.0% of the total discharge capacity of the battery.
