PURPOSE: To enhance the productivity of an electrode for lead-acid storage battery by eliminating necessity for filling an electricity collector with an active substance in a short period of time.
CONSTITUTION: A slurry is prepared by kneading only with water an active substance of lead powder including minimum, and the grating part of a lattice 3 is filled with this slurry to form a slurry layer 2. Diluted sulphuric acid is scattered over the surface of this slurry layer 2 to form a lead sulphate layer 1. Provision of this layer 1, which has a large strength, decreases defect such as hole generation in an electrode plate due to dripping of the slurry even though the viscosity of the slurry layer 2 at the time of application is low. Because of large water content of the slurry, the initial capacity after chemical formation charging is enlarged.
