Abstract

The distribution of electrolyte salt within lithium-ion batteries plays an important role in their performance, particularly under demanding operating conditions and as cells age. However, experimentally quantifying spatial variations in salt concentration remains challenging. This presentation will focus on the development of experimental methods to investigate electrolyte salt distribution in lithium-ion batteries. I will discuss how these techniques can be used to investigate electrolyte salt inhomogeneity and its implications for battery performance, with a particular focus on electrolyte motion-induced salt inhomogeneity in commercial cells.

Short bio

Mahla Bakhshi is a PhD Research Fellow at the University of Agder, Norway, where she works on understanding what limits the performance of lithium-ion batteries. She holds a master's degree in Applied and Engineering Physics from Munich, Germany, and has been working in the battery field since 2020. Before starting her PhD, she worked at Hilti on battery development for power tools and at Battronics in battery consultancy and analysis. During her PhD, she has focused on developing new techniques and experimental setups for battery characterization. She also spent a year in Canada working with the Tesla-Dalhousie research collaboration, investigating electrolyte motion-induced salt inhomogeneity in lithium-ion batteries.'
