Title: Manufacture of lithium cell
Inventor: MATSUMOTO KAZUNOBU
IPC: H01M10/058
Filed: 1986-04-30
Abstract: PURPOSE:To improve the availability of a positive electrode and to increase the cell capacity, by mixing an inorganic compound powder soluble to an organic solvent into a positive electrode active substance, and crushing them. CONSTITUTION:Into positive electrode active substance powder with a layer-form crystalline structure, an inorganic compound powder is added and mixed, and the mixture is crushed. Since the inorganic compound is generally harder than the positive electrode active substance and its crystalline particles have sharp angles, the particles enter between the positive electrode active substance powder particles, and the plate-form planes of the crystalline structure of the positive electrode active substance are pressed by the sharp angles of the inorganic compound particles. Therefore, the positive electrode active substance is crushed rectangular to the layers, that is, in the C axis direction crystallographically. As a result, the diameter of the particles is reduced, the contact area between the positive electrode and the electrolyte is expanded, the availability of the positive electrode is improved, and the cell capacity can be improved. In this case, as the inorganic compound, LiBF4, LiPF6, LiAsF6, LiSbF6, LiCIO4 or the like is used.
