Development of Photoflash Dry Cells

Abstract

This paper describes the development of a LeClanche dry cell of special construction, capable of delivering 33 1/3% greater short‐circuit amperage than is obtained with conventional units. This cell employs a thin paste partition layer and a depolarizing mix of artificial manganese dioxide combined with a high proportion of conductive material, largely acetylene black. The method of fabricating the cell is described and comparative test data are given.
