shows the results of model presented here, and of the
model proposed by Cugnet et al.[2]along with their experimental
data. It must be mentioned that they[2]use the empirical eq.(9)for
Fin their model calculations. Till about 5 h, there are small deviations between results predicted by the present model and their
model. These are due to the neglect of double layer capacity, which
is taken into account by Cugnet et al. [2]. However, from then on,
the model calculations of Cugnet et al.[2]and model calculations
based on the present work are indistinguishable. It can be
concluded that taking into account the resistance of the electrodes
and a justifiable expression forFis as effective as the use of eq.(9),
which is not based on a mechanism. Towards the dead end of
discharge, there are deviations between the observations and
predictions made by either the present model or by their[2]model.
Data of Metzendorf[1]do show that calculated conductivity of lead
oxide electrode is lower than predicted by his model and a more
accurate description of the resistance might improve the
agreement
Calculations show that battery stops discharging if critical
conversion is reached in either of the electrodes, and it is sufficient
if inerts are present in only one electrode to the required level
