Measurement of dE/dT of Mercurous Sulphate Electrode, and Secondary Battery Testing

Abstract

Results obtained in my experiments are sumarized as;
(1) Single potential diffecenee of Normal mercurous sulphate electrode at 18°C is 0.6758 volt on hydrogen scale.
(2) Thechange of e.m.f. of the normal mercurous sulphate electrode with temperature is 0.00026 volt per degree and negative.
(3) E.m.f. of N-mercurous sulphate electrode at t°C is represented by the equation.
Ehg (t)=0.6758-0.00026 (t-18)
(4) Application of this standard electrode to the secondary battery testing is shown in Figs 4 (arrangement of testing), 5 and 6 (characteristic curves of charge and discharge).
