Synthesis-controlled polymorphism, magnetic and electrochemical properties of Li3Co2SbO6
Published 2019Li3Co2SbO6 is found to adopt two highly distinct structural forms: a pseudohexagonal (monoclinic C2/m) layered O3-LiCoO2 type phase with “honeycomb” 2:1 ordering of Co and Sb; and an orthorhombic Fddd phase, isostructural ...Open AccessArticle -
Synthesis, electrochemistry and transition metal-doping of monoclinic Li4Ti5O12 and Na4Ti5O12
Published 2020A new candidate Li-ion battery anode material, monoclinic M-Li4Ti5O12, has been prepared for the first time by ion-exchange from monoclinic M-Na4Ti5O12, and found to offer a stable electrochemical performance at rates of ...Open AccessArticle -
Nickel metaphosphate Ni(PO3)2 as a conversion positive electrode for lithium-ion batteries
Published 2021Lithium storage schemes based on conversion chemistry have been used in a large variety of negative electrodes achieving capacities 2-3 times higher than graphite. However, to date, relatively few positive electrode examples ...Open AccessArticle -
Expanded chemistry and proton conductivity in vanadium-substituted variants of γ-Ba4Nb2O9
Published 2021We have substantially expanded the chemical phase space of the hitherto unique γ- Ba4Nb2O9 type structure by designing and synthesising stoichiometric ordered analogues γ- Ba4V1/3Ta5/3O9 and γ-Ba4V1/3Nb5/3O9, and exploring ...Open AccessArticle -
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
