Magnetic structure and properties of the Na2CoP2O7 pyrophosphate cathode for sodium-ion batteries: a super-superexchange driven non-collinear antiferromagnet
Published 2013The crystal and magnetic structure and properties of the Na2CoP2O7 sodium-ion battery cathode material have been characterized by magnetic susceptibility, specific heat, and variable temperature neutron powder diffraction ...Open AccessArticle -
Synthesis and Characterization of the Crystal and Magnetic Structure and Properties of the Hydroxyfluorides Fe(OH)F and Co(OH)F
Published 2014The title compounds were synthesized by a hydrothermal route from a 1:1 molar ratio of lithium fluoride and transition metal acetate in an excess of water. The crystal structures were determined using a combination of ...Open AccessArticle -
Kröhnkite-type Na2Fe(SO4)2.2H2O as a novel 3.3 V insertion compound for Na-ion batteries
Published 2014Solid-state sulfate chemistry continues to yield promising high-voltage polyanionic cathode materials for rechargeable batter-ies (cf. fluorosulfates and bisulfates). As part of our ongoing exploration of new sulfate ...Open AccessArticle -
A combined experimental and computational study of oxide ion conduction dynamics in Sr2Fe2O5 brownmillerite
Published 2013We report a detailed study of the dynamics of oxide ionic conduction in brownmillerite-type Sr2Fe2O5, including lat-tice anisotropy, based on neutron scattering studies of a large (partially twinned) single crystal in ...Open AccessArticle -
Investigation of K-modified P2-Na0.7Mn0.8Mg0.2O2 as a cathode material for sodium-ion batteries
Published 2019Sodium-ion batteries (NIBs) are emerging as a potentially cheaper alternative to lithium-ion batteries (LIBs) due to the larger abundance of sodium and in some cases the similar intercalation chemistry to LIBs. Here we ...Open AccessArticle
