Synthesis and crystal structures of two polymorphs of Li4–2xMg1+xTeO6
Published 2020Two polymorphs of lithium magnesium tellurate Li4–2xMg1+xTeO6 have been prepared by solid-state reactions and their crystal structures characterised by powder X-ray and neutron diffraction. For x 0, a monoclinic C2/m ...Open AccessArticle -
Insights into the high-voltage layered oxide cathode materials in sodium ion batteries: structural evolution and anion redox
Published 2021The phase evolution and anion redox behaviours under electrochemical cycling of sodium transition metal layered oxides have both been intensively studied. In this review, we focus on the relationship between them at high ...Open AccessArticle -
Elucidation of the high-voltage phase in the layered sodium ion battery cathode material P3-Na0.5Ni0.25Mn0.75O2
Published 2020The P3-type layered oxide Na0.5Ni0.25Mn0.75O2 is a promising manganese-rich positive electrode (cathode) material for sodium ion batteries, with a high working voltage of 4.2-2.5 V vs. Na+/Na and a high capacity of over ...Open AccessArticle -
Manganese metaphosphate Mn(PO3)2 as a high-performance negative electrode material for lithium-ion batteries
Published 2020We report a novel negative conversion electrode material, manganese (II) metaphosphate Mn(PO3)2. This compound can be synthesized by a facile solid-state method, and after carbon-coating delivers an attractively high ...Open AccessArticle -
FeMn3Ge2Sn7O16: a perfectly isotropic 2-D kagomé lattice that breaks magnetic symmetry with partial spin order
Published 2022FeMn3Ge2Sn7O16 is a fully ordered stoichiometric phase containing an undistorted hexagonal kagomé lattice of Mn2+ cations. It represents not only an important expansion of the chemistry of the complex composite FeFe3Si2Sn7O16 ...Open AccessArticle
