Abstract
A lithium secondary battery includes: a positive electrode; a negative electrode; a separator disposed between the positive electrode and the negative electrode; and a nonaqueous electrolyte solution filled between the positive electrode and the negative electrode. The negative electrode includes: an electrically conductive layer having a surface; and lithium metal pieces arranged spaced from each other on the surface of the electrically conductive layer. There is no lithium metal on an imaginary line extending from a first end to a second end opposite to the first end of the surface of the electrically conductive layer and traversing a space between the lithium metal pieces.
