PURPOSE: To improve productivity and volume efficiency of a sealed type lead storage battery by thermally joining a frame made of synthetic resin and a metallic side panel for installing a group of electrode plates each other to be sealed so as to increase the solution injecting speed and remove the dead space in the battery.
CONSTITUTION: A frame 1 and a metallic side panel 2, on which either a positive or a negative plate is fixed, being provided with a thermally joining resin layer are thermally joined each other. After thermally joined, a separator 4 is inserted into the frame 1 as an electrode plate surface is located upper and a specified quantity of electrolyte is injected from the separator surface. Then, the other negative or positive plate composing a group of electrode plates with electrode plates and separators is mounted and the other metallic side panel 2 and the frame 1 are thermally joined each other to be sealed. Thus, diffusion of the electrolyte to the group of electrode plates and displacement of air and the electrolyte in the group are rapidly executed. Therefore, the solution injecting speed is increased, productivity is improved and volume efficiency of the battery is improved about 10%.
