This folder contains reports and loose notes pertaining to research conducted for ESBCo. Included are procedural reports, as well as experimental reports made by members of the ESBCo Research Department and by laboratory employees. The documents cover the period August 1914-January 1923, but most are from 1919-1921. At the beginning of the folder are two undated items that are probably from 1901. The selected items include material relating to the reclamation of copper and nickel from different points in the battery production process, reports on the performance of experimental and rejuvenated cells, and suggested improvements to the Chemical Operations Shop. Also included are detailed reports of the Flake Separating Department and the Inspection Department, as well as reports on research done in preparation for increases in factory production and reductions in expense. The authors include ESBCo employees Julius J. Austin, Robert A. Bachman, C. W. Bissell, F. W. Cunningham, Elmer E. Dougherty, Roy C. Mitchell, Walter H. Patterson, Arthur Pedersen, D. S. Sargent, and Frederick W. Zons.
