Abstract
A half cell using a halide salt of N,N'-bis(substituted phenyl)-4,4'-dipyridyl as the cathode depolarizer has higher discharge voltage than those conventional cells using other organic compounds. Moreover, the primary cells or the secondary batteries therefrom have higher energy density and flatter discharge curves and thus they are very useful as compact and light cells or batteries. 2,4-Dinitrophenyl and 4-cyanophenyl are preferable as the substituted phenyl group.
