1501039 Li or Ca electrodes VARTA BATTERIE AG 22 Sept 1976 [17 Oct 1975] 39319/76 Heading H1B Electric cells are described containing metallic Li or Ca as the negative electrode material, characterized in that before being inserted in the cells, the electrode metal is stored in a gaseous atmosphere of SO 2 , SF 6 or CO 2 to produce a thin, dense, non-hygroscopic film on the surface of the metal. An inert gas (e.g. Ar or He) may be admixed with these gases prior to treatment. Treatment is preferably undertaken at 80‹ to 160‹ C. Exemplified are the preparations of button-type Li cells and lithium cells having spirally wound electrodes, both using LiClO 4 as electrolyte. |
