PURPOSE:To make possible to form an electrode having low bulk density and high strength by mixing organic sublimate with binding material, conductivity assistant and titanium disulfide powder, pressure-forming, and heating up at the two stages of the sublimate temperature and around the melting point of binding material. CONSTITUTION:Titanium disulfide powder, PTFE (polytetrafluoroethylene) as a binding material, acetylene black as a conductivity assistant, and dimethylbenzoquinone as an organic sublimate material are mixed up with the corresponding fractions 45:5:5:45. The mixture is filled up in a metallic mold and pressed to form an electrode. This electrode enclosed in a glass tube is put in an electric furnace and retained firstly for 30min at the sublimate temperature reducing pressure, and then heated up to the melting point 320 deg.C of binding material retaining 2min, and then cooled down. With this method, a low bulk density and strengthened electrode is formed. |
