Journal ArticleDOI
Large Impact of Particle Size on Insertion Reactions. A Case for Anatase LixTiO2
TL;DR: The particle size dependence of insertion reactions has been investigated for lithiated anatase TiO2, revealing progressively increasing Li capacity and Li-ion solubility for decreasing particle sizes, strongly deviating from the expected Li-rich andLi-poor phase separation as occurs in the bulk material.
Journal ArticleDOI
Equilibrium lithium transport between nanocrystalline phases in intercalated TiO2 anatase
TL;DR: The direct observation by solid-state nuclear magnetic resonance of the continuous lithium-ion exchange between the intermixed crystallographic phases of lithium-intercalated TiO2 is reported, finding that, at room temperature, the continuous flux of lithium ions across the phase boundaries is as high as 1.2 × 1020 s-1 m-2.
Journal ArticleDOI
Size Effects in the Li4+xTi5O12 Spinel
TL;DR: In this article, the authors investigated the nanosized Li4+xTi5O12 spinel by electrochemical discharging and neutron diffraction, and the unique zero-strain property of the spinel implies a different origin of the curved voltage profiles observed for its nosized crystallites.
Journal ArticleDOI
In situ methods for Li-ion battery research : a review of recent developments
TL;DR: A comprehensive overview of in situ methods for studying Li-ion batteries is given in this paper, with the emphasis on new developments and reported experimental highlights, as well as some of the most interesting results.
Journal ArticleDOI
Two Phase Morphology Limits Lithium Diffusion in TiO2 (Anatase): A 7Li MAS NMR Study
TL;DR: The chemical shift of lithium in anatase is independent of temperature up to approximately 250 K but decreases at higher temperatures, reflecting a change in the 3d conduction electron densities, and the Li mobility becomes prominent from this same temperature showing that such electronic effects possibly facilitate the mobility.
