Abstract

PURPOSE:To obtain a lithium secondary battery of small size, light weight, and high energy density and high battery energy per volume by press-attaching a lithium sheet to a thin metallic sheet constituting an electrolyte case to make the latter a negative electrode. CONSTITUTION:An electrolyte case 10 is constituting with a positive electrode 14 and a negative electrode 16 with lithium as an activated negative material arranged with a specified spacing in an electrolyte case 10, and a plastic layer 22 laminated on the inner surface of a thin metallic sheet 18. The negative electrode 16 is made by press-attaching a lithium sheet 24 on the thin metallic sheet 18 excluding the plastic layer 22. Namely, lithium of the negative electrode is arranged by press-attaching the lithium sheet 24 on the metallic electrolyte case side which constitute the electrolyte case 10, with the other side of the metallic case where the lithium sheet 24 is not applied is covered with plastic layer 22. Since the lithium sheet is press-applied to the thin metallic sheet constituting the electrolyte case 10, the amount of the material corresponding to the conductor conventionally separately provided can be saved. This makes it possible to obtain a lithium secondary battery of light weight, small size, large energy density, and large battery energy per volume.
