THEORETICAL DESIGN OF PRIMARY AND SECONDARY CELLS. PART III. BATTERY DISCHARGE EQUATION.

摘要

An equation has been derived describing a complete battery discharge for the case when the current density distribution is uniform. The battery potential during discharge is given as a function of time,current density,polarization,internal resistance,and other factors. This equation will be used as a base for deriving the more general case where the current density over the face of the electrodes is uneven. This equation has a number of practical applications. It can be used to describe battery charges and discharges,capacities,power evolution,and predict capacities on the basis of limited data. The equation can be applied to the charging of batteries by changing the signs of some of the terms in the equation. (Author)
