摘要： Porous electrodes are provided for lead-acid storage batteries without supporting plates or grids. The electrodes are porous, self-supporting, structurally integral and electrically continuous. Lead-acid batteries incorporating such electrodes exhibit improved performance characteristics as compared to conventional lead-acid batteries. The electrodes are made by forming a molten mixture of a metal (e.g. lead) and a pore forming component (e.g. cadmium), cooling and forming the molten mixture into a solid electrode with the pore forming component distributed therethrough, removing the pore forming component from the solid electrode to leave a network of voids defining the pores, and oxidizing the metallic walls within the pores to form a coating of electrochemically active material (e.g., lead dioxide) on the walls within the pores.
摘要翻译： 为无酸性蓄电池提供多孔电极，无需支撑板或网格。 电极是多孔的，自支撑的，结构上整体的和电连续的。 与常规铅酸电池相比，包含这种电极的铅酸电池具有改进的性能特征。 电极通过形成金属（例如铅）和成孔组分（例如镉）的熔融混合物而制成，将熔融混合物冷却并形成固体电极，其中孔形成组分分布在其中，从孔中除去成孔组分 固体电极留下限定孔的空隙网络，以及氧化孔内的金属壁，以在孔内的壁上形成电化学活性材料（例如二氧化铅）的涂层。

摘要： A method of generating electrochemical activity in positive plates of Plante cells is disclosed. An agent corrosive to the unformed pure lead positive plate is incorporated in the electrolyte and the cell charged, the corrosive agent being selected to be destroyed by the anodic conditions at the negative plate at the end of the charging cycle. Nitrate ions are preferred.
