Industrial Preparedness Study on Synthetic Battery Grade Manganese Dioxide

摘要

Considerable progress was made on the construction of the one ton a day chemical manganese dioxide pilot plant, during this quarter. Painting, insulating and the acquisition and installation of apparatus, the only remaining activities, will require about one month for completion, after the approval of additional funds.nComparative performance tests were made on batteries, fabricated from acid digested and untreated chemical manganese dioxide, after storage for twelve months. From these and previous tests, it is seen that acid digestion results in a considerable improvement in initial high drain and delayed high and low drain capacities.
