Method for manufacturing lead storage battery
专利汇可以提供Method for manufacturing lead storage battery专利检索，专利查询，专利分析的服务。并且PURPOSE:To prevent dilute sulfuric acid from splashing out of the battery case during the formation process within the battery case and thereby to easily control environmental pollution, by carrying out the formation for the electrode assembly arranged in a sealed battery case provided with a check valve which is adapted to be open when the pressure within the case exceeds a predetermined pressure value. CONSTITUTION:Paste-type anode plates and cathode plates which are not yet formed are arranged into an electrode assembly in such a way that 2 anode plates and 3 cathode plates are piled alternately via a glass mat separator, which remarkably soaks up liquid, inserted in between. And thus obtained electrode assembly is put in a plastic battery case to form an unit cell. Then, 12ml of sulfuric acid whose specific gravity being 1.20 is poured into each unit cell, and then each unit cell is provided with a rubber check valve which is adapted to be open when the internal pressure becomes higher than the atmosphere by 1/4 atmospheric pressure. Thereafter, the forming within the battery case is carried out with 100mA of electric current applied thereto for 90hr. Since the battery case is sealed from the atmosphere during the forming process, the metallic lead serving as the active material for the cathode, which is brought into a chemically active state during the formation, is prevented from being oxided by the air that would be drawn from the atmosphere into the battery and thus, an effective formation can be carried out.，下面是Method for manufacturing lead storage battery专利的具体信息内容。
