Title: Heat dissipation of primary and secondary batteries. [30-Ah Ni--Cd, 360-Ah Ag--Zn]

Abstract

Calorimetric data are given for the heat generated in a 30-Ah nickel-cadmium battery and a 360-Ah silver--zinc battery. Equations are also given to calculate the amount of heat generated. Heat dissipation in the silver(II) oxide region is about 20% less than in the silver(I) oxide region; also for silver--zinc cells, heat dissipation above 21 C, because of self-discharge, is an exponential function of temperature. About 70% of heat generated is due to polarization losses, the remainder is due to chemical inefficiencies. In nickel--cadmium batteries, a linear relationship is found between heat generation and current where I/sup 2/R heating is not significant.
