摘要

The lead oxide electrode is a grid or plate (A) comprising specific ceramic or intermetallic compounds, such as titanium silicium carbide. This provides a considerable weight economy and is for use with lead-sulphuric acid-lead dioxide batteries. To improve electrical contact between on the one hand the grid or plate and on the other hand the lead dioxide, preferably between them is fitted a lead layer by electrolytic plating of the grid or plate in alkaline electrolyte. The grid involved (B) has squares for the porous lead oxide mass used with positive electrodes. The positive electrode formed by the forementioned core has much higher resistance force against performance deterioration, particularly in cases where a lead battery remains uncharged or only partly charged for a longer time.
