NOVELTY - A specific ore is pulverized. Hot spring water containing pulverized ore is mixed with specific solvent, and solvent of specific function is obtained. The obtained solvent is coated on surface of aluminum foil or copper foil (3), and solvent-coated surface (2) is formed. An adhesive layer (4) and a releasing paper (5) are sequentially formed on other surface of aluminum foil or copper foil to manufacture sheet (1).    USE - For manufacturing deterioration preventing and regeneration promoting sheet used for secondary batteries and mobile telephones (both claimed).    ADVANTAGE - The sheet preventing deterioration of electrolytic liquid and electrode in a secondary battery, is simply, effectively and inexpensively manufactured. The sheet suppresses production of sediments adhering to inside portion of the electrolyte liquid or electrode. The sheet subdivides sediments adhering to inside portion of the electrolyte liquid, and enables ions to move easily. The sheet improves charging and discharging capacity of the battery, and hence promotes regeneration of the deteriorated secondary battery. The sheet is highly safe with respect to radioactivity.    DETAILED DESCRIPTION - A hot spring ore containing radium and thorium is pulverized. Hot spring water containing pulverized hot spring ore is mixed with polyurethane-type solvent, and a solvent which promotes regeneration and prevents deterioration of secondary battery is obtained. The obtained solvent is spray-coated or roll-coated on a surface of aluminum foil or a copper foil (3) and a solvent-coated surface (2) is formed. An adhesive layer (4) is formed on the other surface of the aluminum foil or copper foil. A releasing paper (5) is further laminated to the other surface of adhesive layer to manufacture deterioration preventing and regeneration promoting sheet (1) of secondary battery.    An INDEPENDENT CLAIM is included for usage of deterioration preventing and regeneration promoting sheet of secondary battery.
