Partial Report on Studies of Grid Alloys for Submarine Storage Batteries

Abstract

This letter summarizes the results of life-tests on storage batteries of the "starting and lighting" type, using grids made of 14 different alloys. These included compositions of a type which previous work at the Naval Research Laboratory and the National Bureau of Standards had indicated were promising. The results indicate that grids made of lead containing2-1/2 antimony, and .05 to .10 silver resist anodic oxidation better than grids of stcll1dard composition (8 to 11 antimony)while producing negligible sulfation and self-discharge in the negative plates. The hardness and strength of these alloys is of the same order but somewhat greater than that of the standard composition and is due to the combined effect of the antimony and the silver. No composition of the series tested containing strontium gave satisfactory positive grids under the conditions of the testal though in most instances the outward appearance of the grid proper upon dissembling the cells was excellent, Tests with calcium and barium have, in the past, sho1m no encouraging results.
