Comment on "Conductivity of Concentrated Electrolytes"

TL;DR

This paper critiques a recent analytical model for electrolyte conductivity, arguing it is invalid at high molar concentrations due to its assumptions.

Contribution

It provides a critical analysis of the applicability of an existing conductivity model at concentrated electrolyte conditions.

Findings

The model does not hold at high molar concentrations.

Analytical expressions need modification for concentrated electrolytes.

Highlights limitations of current theoretical approaches.

Abstract

We argue that the analytical expression for electrolyte conductivity derived by Avni et al. (arXiv:2110.07008) does not apply at molar concentrations.
