ORGANIC ELECTROLYTE CELL AND MANUFACTURE THEREOF

摘要

PURPOSE:To improve electric contact of positive electrode with a positive electrode case while facilitating cell manufacture by making ruthenium oxide to be contained inside a positive electrode mixture while so as to much exist especially on a surface layer of the positive electrode mixture. CONSTITUTION:A positive electrode mixture 5 having graphite fluoride as a positive electrode active material directly comes in contact with a positive electrode case 6 to form an organic electrolyte cell. The positive electrode mixture 5 contains ruthenium oxide, while its distribution is made to much exist especially on the surface of the positive electrode mixture 5. Ruthenium oxide is conductive for becoming a conductive material of the positive electrode and having large bulk density so that a positive electrode filling quantity is so much increased while being stable to thermal decomposition. Ruthenium oxide is made by thermal decomposition of ruthenate at a temperature of 250 to 450 deg.C so that manufacture of the positive electrode mixture and filling thereof is easy, and thus the cell is easily manufactured.
