Correlation of MetalIon Coordination with MechanicalProperties and Ionic Conductivity in Homogeneous PEG-Based NetworkSolid Electrolytes

Abstract Understanding the relationship between metal ion coordination within polymer networks and macroscopic properties is a key factor in designing polymer electrolytes. In this study, homogeneous tetra/linear-PEG solid electrolytes were prepared by combining tetrafunctional a...

Free-EnergyProfile of Li-Ion Insertion Reaction inHighly Concentrated Electrolytes: Impact of Destabilized Li-Ion onElectrode Reaction Thermodynamics

Abstract Understanding the Li-ion insertion reaction at graphite electrodes as a chemical reaction requires a thermodynamic perspective, namely elucidating the underlying free-energy profile. In this study, we quantitatively constructed the free-energy profile of the Li-ion inser...
