Abstract
A lithium secondary battery including a negative electrode in which a negative electrode mixture included in the negative electrode is formed by charge and discharge of the battery. This negative electrode is formed by charge-induced formation of lithium metal on a negative electrode current collector having a three-dimensional structure form. The lithium secondary battery forms lithium metal while being blocked from the atmosphere. Therefore, formation of a surface oxide layer (native oxide layer) on a negative electrode is blocked and a lithium dendrite growth suppressing effect is achieved by forming lithium metal on a negative electrode current collector having a three-dimensional structure form. The lithium secondary battery has a superior battery efficiency and reduces declines in lifetime properties.
