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 -
Na2FeP2O7: A Safe Cathode for Rechargeable Sodium-ion Batteries
Published 2013Vying for newer sodium-ion chemistry for rechargeable batteries, Na2FeP2O7 pyrophosphate has been recently unveiled as a 3 V high-rate cathode. In addition to its low cost and promising electrochemical performance, here ...Open AccessArticle -
Alkali metal modified P2 NaxMnO2: Crystal structure and application in sodium-ion batteries
Published 2020Sodium-ion batteries (NIBs) are an emerging alternative to lithium-ion batteries because of abundant sodium re-sources and the potentially lower cost. Here we report the Na0.7MnO2 solid-state synthesized at 1000 oC which ...Open AccessArticle
