PURPOSE:To obtain the captioned storage battery with high coulomb efficiency of charge-and-discharge and long life time, by constituting the positive electrode body with a filmy substance consisting of spherical polymer of a specified pyrrole-system compound and with a collecting conductor which sticks to said filmy substance. CONSTITUTION:Nonaqueous electrolyte solution 2 is formed by dissolving pyrrole-system compound monomer and supporting electrolyte substance in polar organic solvent. Next, the positive electrode 31 and the negative electrode 32 are dipped into said solution so as not to touch each other, and DC voltage is applied between said two electrodes. And, pyrrole-system compound monomer is subjected to electrolytic polymerization reaction in order to form a filmy substance 41 which is made from spherical polymer of pyrrole-system compound on the surface of the positive electrode 31. In this case, an electrification time is so decided that the bulk density of the filmy substance 41 grows to 0.4-1.3g/cm<3>. Next, the filmy substance 41 of polypyrrole-system compound is taken out of an electrolytic container 1 and is stuck onto a collecting conductor 42 in order to produce the positive electrode body 4 of the storage battery. |
