Query: Temperature effects on the ionic conductivity in concentrated alkaline
  electrolyte solutions   Alkaline electrolyte solutions are important components in rechargeable
batteries and alkaline fuel cells. As the ionic conductivity is thought to be a
limiting factor in the performance of these devices, which are often operated
at elevated temperatures, its temperature dependence is of significant
interest. Here we use NaOH as a prototypical example of alkaline electrolytes,
and for this system we have carried out reactive molecular dynamics simulations
with an experimentally verified high-dimensional neural network potential
derived from density-functional theory calculations. It is found that in
concentrated NaOH solutions elevated temperatures enhance both the
contributions from proton transfer to the ionic conductivity and deviations
from the Nernst-Einstein relation. These findings are expected to be of
practical relevance for electrochemical devices based on alkaline electrolyte
solutions.
