PURPOSE:To prevent the dropping out of an electrode active material by providing a filamented fluorine resin layer on the surface of a battery electrode having a three-dimensional base as an electrode base. CONSTITUTION:An electrode formed by charging an active material 6 in a foamed nickel having a porosity of 96% followed by drying and pressure molding is continuously moved in one direction while heating to 60-80 deg.C. A first brush is fixed orthogonally to the moving direction, and a fluorine resin suspension is applied to the electrode surface while being penetrated from a tank above the brush. Simultaneously with the application, the filamenting of the fluorine resin is realized by the friction with the contact surface of the brush, and the filamenting is complicated by a second brush operated orthogonally to the moving direction of the electrode. The dropping out of the active material 6 in the electrode can be prevented by a complicatedly intertwined filamented fluorine resin 8 layer. |
