PURPOSE:To make a battery compact by installing openings on the opposite sides of a lead material plate embeded in a plastic plate and connecting a positive plate to its one side and a negative plate to its other side. CONSTITUTION:A lead material plate 7 consists of pure lead, lead-calcium alloy, or lead-antimony alloy. The lead material plate 7 is embedded into a plastic plate 8, and openings 9 and 9' are installed on its one side and an opening 10 is on its other side. A positive plate is connected to one opening and a negative plate is to the other opening. Thereby, since thickness of lead material plate is made thin, the battery is made compact. |
