Superionic Amorphous Li2ZrCl6 and Li2HfCl6

Advanced Materials, EarlyView.
Amorphous Li2HfCl6 and L2ZrCl6 are shown to be promising solid‐state electrolytes with predicted ionic conductivities >20 mS·cm−1. Molecular dynamics simulations with machine‐learning force fields reveal that anion vibrations and flexible MCl6 octahedra soften the Li coordination cage and enhance mobility. Correlation between Li‐ion diffusivity and the

Solid state electrolytes for all-solid-state 3D lithium-ion batteries

, 2012
The focus of this Ph.D. thesis is to understand the lithium ion motion and to enhance the Li-ionic conductivities in commonly known solid state lithium ion conductors by changing the structural properties and preparation methods. In addition, the feasibility for practical utilization of several studied solid electrolyte materials in 3D all-solid-state ...

Chemomechanical Origin of Morphological Disparity in Lithium Metal Electrodeposition

Advanced Materials, EarlyView.
Selective dissociation of either solvent or salt on copper current collector induced different solid electrolyte interphase (SEI) layers. The solvent derived organic SEI favors formation of Li whisker, while salt derived SEI favors formation of Li particle, revealing the root cause of Li morphology disparity within the same cell.

Redefining Separator Design and Water Activity for High‐Energy Zinc Batteries Using Covalent Organic Framework

Advanced Materials, EarlyView.
Device‐level zinc batteries are energy‐limited by the mass/volume of inactive components, while lean‐electrolyte operation triggers interfacial water depletion and unstable kinetics. Here we elucidate lean‐failure mechanisms and develop a COF@PAN functional separator that regulates hydrogen‐bonding networks to manage water activity and accelerate ...

Self‐Regulating Sodium‐Ion Battery Materials: From Phase Reconstruction to Functional Activation

Advanced Materials, EarlyView.
Self‐regulating sodium‐ion batteries hinge on programmable phase behavior in layered oxides, interphases that renew without growth, and electrolytes that steer solvation and chemistry. This review distills mechanisms into design rules that span composition, site and entropy tuning, and self‐buffering anodes, linking operando evidence to choices and ...
