Abstract
A method for manufacturing a lithium secondary battery that can exhibit improved capacity and energy density compared to existing lithium ion batteries and lithium metal secondary batteries, and has excellent safety and lifetime characteristics. The method includes assembling a battery comprising an anode, a cathode, a separator, and an electrolyte, and charging the battery. In the step of assembling the battery, a ratio of an anode load amount to a cathode load amount (N/P ratio) is 0.01 to 0.99, and in the step of charging the battery, charging is performed based on the cathode load amount.
