title: Titanium migration driven by Li vacancies in Li(1-x)Ti2O4 spinel.
abstract: Gentle oxidation of lithium titanate spinel (LiTi2O4) with water at room temperature gives Li-deficient Li0.33Ti2O4. Combined X-ray and neutron Rietveld analysis shows that 28% of the Ti cations are displaced to alternative octahedral sites, in keeping with a proposed model based on Ti-migration limited by Li-vacancy concentration.
