Impact of Ionic Correlations on Selective Salt Transport in Ligand-Functionalized Polymer Membranes

Harnoor Singh Sachar et al.

Summary: We present a theoretical formalism that quantifies the interplay between cation-ligand interaction strength and dynamical ionic correlations on salt diffusivities in ligand-functionalized polymer membranes. Our results show that ionic correlations speed up the diffusivities of both ligand-selective and ligand-agnostic salts compared to the ideal, uncorrelated case. The speedup is due to positively correlated motion among mobile ions at low interaction strengths and correlated hopping of cations bound to ligands at high interaction strengths.

Li-Ion Transport and Solvation of a Li Salt of Weakly Coordinating Polyanions in Ethylene Carbonate/Dimethyl Carbonate Mixtures

Shinji Kondou et al.

Summary: The study found that poly(LiSTFSA) exhibited the highest ionic conductivity in the lowest polar mixture at the highest salt concentration, attributed to a unique conduction phenomenon. This provides insights into a new design strategy for nonaqueous liquid electrolytes for LIBs.

Electric-Field-Induced Spatially Dynamic Heterogeneity of Solvent Motion and Cation Transference in Electrolytes

David M. Halat et al.

Summary: The study found that electric fields primarily result in migration of charged species in electrolytic solutions, and different solvation motifs and concentrations can affect the cation transference number. At a certain concentration, the dynamic heterogeneity of solvent molecules is minimized and the transference number approaches zero.

Polyhedral Oligomeric Silsesquioxane-Based Macroanions to Level Up the Li+ Transport Number of Electrolytes for Lithium Batteries

Thi Khanh Ly Nguyen et al.

Summary: This paper focuses on increasing the lithium transport number by synthesizing POSS-based macroanions and studying their properties in electrolytes. It is found that the size of macroanions has a significant impact on transport number, electrolyte viscosity, and tortuosity. The chemical affinity between the organic POSS shell and the solvent also affects the dissociation rate of Li+ ions.

Chelating Additives Reversing the Lithium Migration Direction in Ionic Liquid Electrolytes

Florian Ackermann et al.

Summary: The study investigates the influence of coordinating additives on lithium ion migration in ionic liquid mixtures, showing that strongly coordinating additives can reverse lithium migration direction and increase drift of neutral molecules. This effect depends strongy on the chelating ability of the additive, with strongly coordinating additives forming chelates with the Li ion to enhance its drift velocity.

Interfacial Effects on Transport Coefficient Measurements in Li-ion Battery Electrolytes

Helen K. Bergstrom et al.

Summary: Developing Li+-containing electrolytes with improved transport properties requires reliable techniques to understand ion-transport. This study applied a potentiostatic polarization-based approach to measure transport coefficients in liquid electrolytes, revealing challenges in characterizing electrolyte systems where interfacial resistance is significantly larger than ohmic electrolyte resistance. Methods relying on potentiostatic Li metal stripping/plating did not reliably determine liquid electrolyte transport coefficients.

Ionic Liquid in Li Salt Electrolyte: Modifying the Li+ Transport Mechanism by Coordination to an Asymmetric Anion

Marc Brinkkoetter et al.

Summary: The study demonstrates that in binary ionic liquid/Li salt electrolytes, the use of asymmetric anions can reduce crystallization tendencies and enable liquid systems with high Li concentration. The research elucidates the local coordination environment of Li and its correlation with Li+ ion transport properties, providing insights into the structural Li+ ion transport which is crucial for developing efficient ionic liquid-based batteries.
