MICROGRAPHY OF TUBULAR-TYPE BATTERY PLATES.
Abstract
Tubular type battery plates of various stages of production were obtained from three battery manufacturers and examined microscopically. It was ascertained that certain physical changes took place in the microstructure of the material after soaking in acid and after forming. These changes were not the same as those that occurred when plates were prepared from mixed and cured paste and subsequently formed. To all visible appearances the product from the tubular plate appeared to have cohesion and porosity equal to or better than from most pasted plates. However, the adherence of the paste to the metal spline was poor. Of particular interest was the discovery that the formed active material of one of these manufacturers contained a definite reticulate structure such as had previously been found to coexist with plates that successfully floated without loss of capacity.
