Abstract
An electric cell comprising a positive electrode, a negative electrode, and an electrolyte containing a lithium salt is provided wherein the negative electrode has a two-layer structure of a lithium-aluminum alloy layer and an aluminum layer. The cell is fabricated by placing a positive electrode, a negative electrode, and an electrolyte in a cell container comprising positive and negative electrode casings, and forming a seal between the positive and negative electrode casings. The negative electrode is electrochemically formed in situ in the cell container from a lithium-clad aluminum substrate.
