PURPOSE:To obtain a cell stable and not having the deterioration of conductivity even in the air by polymerizing polypyrrole on conductive substrates as a positive electrode, using an alkali metal as a negative electrode, and bringing them into contact with an electrolyte. CONSTITUTION:Pyrrole is added to an electrolytic solution made by solving an electrolyte in an organic solvent. A pair of conductive substrates made of platinum, etc. are immersed in this solution and are electrolyzed at the current density of 1-20mA/cm<2> to polymerize polypyrrole on the substrates. The polypyrrole thus obtained is used as a positive electrode and an alkali metal such as Li is used as a negative electrode to assemble a cell, and they are brought into contact with the electrolyte. According to this method, a cell excellent in conductivity and having a long life can be efficiently produced. |
