The Effects of Sulfuric Acid and Vanadium Cations on the Morphology of Hydrated Nafion: MD Simulations
Abstract
The vanadium redox flow battery (VRFB) is one of the promising electrical energy storage technologies in providing stable electricity supply from the primary solar and wind enery sources.1 For practical operation, it is critical to understand the electrolyte ion behavior within the VRFB membrane separator to gain insight into the ion permeation process. Here, we report our recent molecular dynamics (MD) investigations on the structure and interaction between hydrated Nafion membrane and the ionic species of the electrolyte solution: V2+, V3+, and HSO4 –.
