When using a separator that contains an organic additive with
water loss reducing properties, e.g., Daramic V, the current flow
is reduced significantly, i.e., by about 30–40% as demonstrated
by the lower curve in Fig. 4. The weight loss that these batteries
exhibit due to decomposition of water by electrolysis is proportional
to the total overcharge, i.e., the integral of current over
time, in accordance with Faraday’s law.
