Journal ArticleDOI
Diffusion and migration in polymer electrolytes
Youngwoo Choo,David M. Halat,Irune Villaluenga,Ksenia Timachova,Ksenia Timachova,Nitash P. Balsara,Nitash P. Balsara +6 more
TL;DR: Choo et al. as discussed by the authors used the Stefan-Maxwell diffusion coefficients to predict the velocities of the ions at very early times after an electric field is applied across the electrolyte.
Journal ArticleDOI
Evolution of the Electrode–Electrolyte Interface of LiNi0.8Co0.15Al0.05O2 Electrodes Due to Electrochemical and Thermal Stress
Zachary W. Lebens-Higgins,Shawn Sallis,Nicholas V. Faenza,Fadwa Badway,Nathalie Pereira,David M. Halat,Matthew J. Wahila,Christoph Schlueter,Tien-Lin Lee,Wanli Yang,Clare P. Grey,Glenn G. Amatucci,Louis F. J. Piper +12 more
TL;DR: In this paper, the authors studied the evolution of CEI species as a function of electrochemical and thermal stress for LiNi0.8Co0.15Al0.05O2 (NCA) particle electrodes using a LiPF6 ethylene carbonate:dimethyl carbonate (1:1 volume ratio) electrolyte.
Journal ArticleDOI
Characterizing Oxygen Local Environments in Paramagnetic Battery Materials via 17O NMR and DFT Calculations
Ieuan D. Seymour,Derek S. Middlemiss,David M. Halat,Nicole M. Trease,Andrew J. Pell,Andrew J. Pell,Clare P. Grey +6 more
TL;DR: The methodology for studying (17)O shifts in paramagnetic solids described in this work will be useful for studying the local environments of O in a range of technologically interesting transition metal oxides.
Journal ArticleDOI
Surface-selective direct 17O DNP NMR of CeO2 nanoparticles.
Michael A. Hope,David M. Halat,Pieter C. M. M. Magusin,Subhradip Paul,Luming Peng,Clare P. Grey +5 more
TL;DR: Polarisation build-up curves show that the polarisation of the (sub-)surface sites builds up faster than the bulk, accounting for the remarkable surface selectivity of surface-selective direct 17O DNP.
Journal ArticleDOI
In Situ Raman Studies of Carbon Removal from High Temperature Ni–YSZ Cermet Anodes by Gas Phase Reforming Agents
TL;DR: In situ vibrational Raman scattering has been employed to examine rates of carbon formation and removal from Ni/YSZ cermet anodes in functioning, electrolyte-supported solid oxide fuel cells (SOFCs) as mentioned in this paper.
