Abstract
Estimated values of self-discharge rates of various miniature cells obtained by calorimetry were compared with actual values. The estimated self-discharge value of a Nickel-Cadmium battery was nearly equal to the actual value. The estimated self-discharge values of primary cells (i. e. silver oxide, mercuric oxide, alkaline manganese dioxide and lithium cells) were a little smaller than the actual values, but the temperature dependence of the former was equal to that of the latter. The application of calorimetry to cells is considered to be useful to estimate self-discharge rates of various cell systems and newly developed cell systems as well as to design a cell construction by self-discharge or to control a cell production by self-discharge.
