Engineering a Fluorinated AlPO4 Interface: Toward High Initial Coulombic Efficiency and Stable Oxygen Redox in Li‐Rich Layered Oxide Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
We report a chemically incorporated fluorinated AlPO4 (AlPO4‐F) architecture that functions as a multifunctional “interfacial fortress” for Li‐rich layered oxides (LLOs). By modulating the surface potential to –32.16 mV, this architecture enriches Li+ concentration and repels detrimental electrolyte anions.

An exploration of Li-ion cell relaxation using EIS [PDF]

open access: yes, 2014
This paper describes a systematic study of the effect of cell relaxation after a charge or discharge event. The EIS technique was used to investigate how the properties of the cells changed with time after charge or discharge up to a maximum of 15 hours.

Investigations of rate limitation in nanostructured composite electrodes and experiments towards a 3D Li-ion microbattery

open access: yes, 2011
The factors effecting discharge rate limitation within LiFePO4 composite electrode structures have been investigated. It was found that for composite electrodes containing ‘small particles’ of active material solid state processes are not necessarily ...

Lithium-ion Conductors of NASICON-structured Ca2+ Substituted LiZr2(PO4)3 Solid Electrolytes Obtained by Heat Treatment of Amorphous Materials in the Li2O-CaO-ZrO2-P2O5 System

open access: yesElectrochemistry
Amorphous powder in the Li2O-CaO-ZrO2-P2O5 system were prepared by using mechanochemical synthesis process at room temperature. Amorphous materials with the nominal composition of Li1+2xCaxZr2−x(PO4)3 (LCZP) (x = 0.05, 0.08, 0.1) were calcinated at 900 ...

Mechanistic Origins of Chemo‐Mechanical Instability and Failure in Solid‐State Lithium‐Sulfur Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Conversion‐induced sulfur expansion generates strong mechanical constraints and localized stresses within solid‐state Li‐S cathodes. Heterogeneous solid‐electrolyte confinement creates tensile strain‐energy hotspots that govern particle cracking. Larger sulfur particles accelerate fracture, while higher porosity relaxes constraint and delays damage ...

Modeling current density and SoC distribution of all-solid-state lithium-ion batteries

open access: yesElectrochemistry Communications
Researchers have conducted in-depth investigations into lithium-ion battery models. However, a notable limitation of existing models lies in the assumption of infinitely conductive current collectors, which compromises simulation accuracy.

Role of Structural Disorder on Phonon Transport and Thermal Conductivity in Li6PS5Br

open access: yesAdvanced Functional Materials, EarlyView.
Solid electrolytes are fast ion and slow heat conductors. Although both transport properties are governed by lattice dynamics and atomic structure, their interplay remains poorly understood. Here, we study this interrelation in anion‐ordered and disordered Li6PS5Br.

An investigation of the feasibility of a spacecraft multifunctional structure using commercial electrochemical cells

open access: yes, 2009
Multifunctional structures offer the potential for large savings in the mass and cost of spacecraft missions. By combining the functions of one or more subsystems with the primary structure, mass is reduced and internal volume freed up for additional ...
