PURPOSE:To unify the liquid distribution in an electrode plate and improve the utilization factor by filling the paste mainly made of lead oxide, dilute sulfuric acid and water prior to aging and drying in a lattice body concurrently serving as a current collecting plate, spraying or wetting a dilute sulfuric acid aqueous solution with specified specific gravity while the paste has plasticity, and pressing it to smooth the surface. CONSTITUTION:In a sealed type lead-acid battery, an electrolyte is contained in positive and negative electrode plates and a separator, and free electrolyte rarely exists. The electrode plate of such battery is manufactured as follows: The paste mainly made of lead oxide, dilute sulfuric acid and water is filled in a lattice body made of lead or plastic, then a dilute sulfuric acid aqueous solution with the specific gravity of 1.00-1.20 is sprayed or wetted on the electrode plate while the paste has plasticity prior to aging and drying, it is pressed with a flat plate or a roller, and the surface roughness of the electrode plate is set to 50mum or below. The group pressure of the battery is made constant, and the adhesion between the electrode plate and the separator is improved. |
