Ion Solvation Engineering: How to Manipulate the Multiplicity of the Coordination Environment of Multivalent Ions
Advanced free-energy sampling analysis shows that the multiplicity of thermodynamically stable solvation configurations is a general feature of free divalent cations, their ion-pairs and neutral aggregates in low dielectric solvents. We reveal the macro- and microscopic factors of the solvation multiplicity and show how their interplay can be used to manipulate ion solvation environments and thus the ion solvation-desolvation dynamics.

Direct observation of cyclic polymer dynamics in shear flow reveals non-equilibrium behavior for flow-based applications
Single ring polymers were directly visualized in the flow-gradient plane of shear flow to understand their dynamic behavior such as tumbling and stretching in flow, as well as the distribution of polymer conformations far-from-equilibrium. Read More

Oxygen Facilitates Mg2+ Diffusion Through Fe3O4
Controlled processing of carefully designed Fe3O4/MgO heterostructures allowed identification of the Mg2+ diffusion pathways, reaction intermediates, and the key role of the anion in these energy-relevant systems. Read More

A Highly Concentrated Electrolyte for High Capacity and Coulombic Efficiency in Li-NCM811 Cells
Replacing a dilute 1 M LiPF6-based electrolyte with a hydrofluoroether (HFE)-modified highly concentrated electrolyte (HCE) stabilizes the Li metal interface and results in higher discharge capacity, Coulombic efficiency, and thermal stability. Read More

Modeling the Interface Between Lithium Metal and its Native Oxide
The transport of Li+ within the amorphous Li/Li2O interface is predicted to be roughly three orders of magnitude faster than in crystalline Li2O (as determined in the literature). Read More

High-Voltage Phosphate Cathodes for Rechargeable Ca-Ion Batteries
Two functional polyanionic phosphate materials, NASICON-type NaV2(PO4)3 and olivine-type FePO4, are demonstrated as high voltage Ca-ion battery cathodes for the first time. Read More

Impact of Frictional Interactions on Electrochemical Properties in Polymer Electrolytes
We introduce a new parameter, b+-, indicating the influence of cation-anion interactions on conductivity. When b+- = 1, which is true in the fluorinated system, only cation-anion interactions determine ionic conductivity. Read More

X-ray-Induced Lithium Fluoride Formation from Water-in-Salt Electrolytes on Solid Surfaces
LiTFSI/H2O electrolyte interfacial decomposition pathways in the “water-in-salt” (WiSE) and “salt in-water” regimes are investigated using synchrotron X-rays. The resultant photoelectron-induced reduction towards LiF formation was revealed to be occur among closely contact ion-pairs adjacent to the interface. This supports present models behind the WiSE concept. Read More
