[NM036-N] Notebook, E-4298 (1904, 1927)
This notebook was used by Edison during November 1904. There is one additional entry from 1927. It contains notes and drawings relating to experiments with alkaline storage batteries that may have been transcribed from other notebooks. The entries describe numbered groups of experimental cells to be constructed and indicate the results of tests performed on them. The groups of cells differ in their construction and chemical composition. Included are groups made with molasses, glucose, potassium cyanate, and various preparations of nickel hydroxide. Other groups are distinguished by differing treatments of cups and grids and differing charge or discharge conditions. The entry from 1927 is a brief note about a 1904 entry pertaining to iodides in electrolytes. The notebook contains 300 numbered pages; many pages are blank.
