Fast Sodium Ion Conductivity in Pristine Na8SnP4: Synthesis, Structure and Properties of the Two Polymorphs LT‐Na8SnP4 and HT‐Na8SnP4

open access: yesAngewandte Chemie, EarlyView.
Sodium‐ion conductors show great promise for use in rechargeable solid‐state batteries due to the high natural abundance of sodium. As a pristine material, Na8SnP4 demonstrates relatively high ionic conductivity and offers significant room for further enhancement, owing to its structure built on well‐known tetrahedral building blocks. Additionally, its

Nominal Lanthanum Niobate, a Versatile Additive for Reducing Grain Boundary Resistance in Conductive Ceramics

open access: yesAdvanced Energy Materials, EarlyView.
The grain boundaries of well‐known conducting ceramics, like Na+‐ion conducting Na3.4Zr2Si2.4P0.6O12, Li+‐ion conducting Li1.5Al0.5Ti1.5P3O12 and Li0.34La0.56TiO3, O2‐‐ion conducting Y0.148Zr0.852O2‐δ and electronic conducting SrTiO3, are reinforced by adding 0.5‐3 mol% LaNbO4 without changing the density of the ceramic, resulting in much lower grain ...

Concurrent Operando Neutron Imaging and Diffraction Analysis Revealing Spatial Lithiation Phase Evolution in an Ultra‐Thick Graphite Electrode

open access: yesAdvanced Energy Materials, EarlyView.
The lithiation phases in an ultra‐thick graphite electrode are mapped operando as a function of electrode depth through a new method concurrently combining neutron imaging and diffraction. The results reveal the coexistence of lithiation phases during cycling as well as the solid electrolyte interface (SEI) formation and capacity loss through non ...

Uncovering Chemical Principles Governing Nanophase Formation in Ternary Solvents

open access: yesAngewandte Chemie, EarlyView.
Here, we report an experimental investigation of how the types of intermolecular interactions present between systematically varying pairs of cosolvents and oils bias the formation of thermodynamically stable nanophases when mixed with water. We focus on the role of different functional groups or chemical characteristics (alcohols, carboxylic acids ...

Bimodal Ionic Conduction through Polymer Films due to Nano Confinement

open access: yesAngewandte Chemie, EarlyView.
This minireview revisits the phenomenon of nano‐confined ion conduction through polymer films. Ions diffuse through polymer films in two distinct modes depending on the nano‐structure and free space for the passage of hydrated or partially hydrated ions.

Li21Ge8P3S34: New Lithium Superionic Conductor with Unprecedented Structural Type

open access: yesAngewandte Chemie, EarlyView.
The discovery of high ion‐conductive inorganic crystal structures remains a challenge in facilitating the development of all‐solid‐state batteries. Ionic conductors reported to date have predominantly been limited to well‐known crystal structures. In this work, we report a new, unprecedented crystalline structure, Li21Ge8P3S34, which demonstrates high ...
