414,824. Batteries. GRIEBEL, K., 123, Clemensstrasse, Munich, Germany. March 31, 1933, No. 9766. [Class 53.] An accumulator is provided with negative electrodes consisting of an alkali or alkaline earth metal, the positive electrode consisting of a metal hydroxide. The electrolyte is a solution of sodium hydroxide, and in order to lessen the chemical action at the negative electrodes they are placed in contact with the walls of the containing vessel and covered with a porous diaphragm, and an organic substance such as glycerin is added to the electrolyte. Fig. 1 shows a cell in which g, g' are the diaphragms in the form of thin clay plates which cover the negative electrodes f, f<1> which may be amalgamated with mercury. The positive electrode e may consist of manganous hydroxide and is separated from the negative electrodes by diaphragms b, b<1>. A solution of sodium hydroxide is placed in all the compartments of the cell, glycerin being added to the solution in the end compartments containing the negative electrodes f, f<1>. |
