PURPOSE:To obtain a sealed lead-acid battery, which can be manufactured easily and which has a large discharge capacity. CONSTITUTION:In a sealed lead-acid battery, a clearance between a positive electrode plate and a negative electrode plate and the circumference of a plate group are filled with granular silica, and this granular silica and plate group are practically impregnated with sulfuric acid electrolyte at a quantity required and sufficient for charge and discharge of the battery. The granular silica is mixed with the spherical silica at 50-500mum manufactured by the sol./gel method. |
