Abstract
The present invention relates to a lithium secondary battery manufactured by forming a negative electrode free battery and then forming a lithium metal on the negative electrode current collector by charging.In the lithium secondary battery, since lithium metal is formed on the negative electrode current collector in the state of being blocked with the atmosphere, the generation of the conventional surface oxide layer (native layer) formed on the negative electrode does not occur inherently, thereby preventing the reduction of the efficiency and lifetime characteristics of the battery.
