  • Evidence of enhanced ion transport in Li-rich silicate intercalation materials 

    Billaud, Juliette; Eames, Christopher; Tapia-Ruiz, Nuria; Roberts, Matthew R.; Naylor, Andrew J.; Armstrong, A. Robert; Islam, M. Saiful; Bruce, Peter G. (2017-06-07) - Journal article
    The silicate compounds Li2MSiO4 (where M = Mn, Fe, Co) have received significant attention recently as Li intercalation electrodes. Overwhelmingly they exhibit relatively poor kinetics of ion intercalation. By synthesizing ...
  • High voltage Mg-doped Na0.67Ni0.3-xMgxMn0.7O2 (x = 0.05, 0.1) Na-ion cathodes with enhanced stability and rate capability 

    Singh, Gurpreet; Tapia-Ruiz, Nuria; Lopez Del Amo, Juan Miguel; Maitra, Urmimala; Somerville, James W.; Armstrong, A. Robert; Martinez de Ilarduya, Jaione; Rojo, Teófilo; Bruce, Peter G. (2016-07-26) - Journal article
    Magnesium substituted P2-structure Na0.67Ni0.3Mn0.7O2 materials have been prepared by a facile solid-state method and investigated as cathodes in sodium-ion batteries. The Mg-doped materials described here were characterized ...
  • Li(V0.5Ti0.5)S2 as a 1V lithium intercalation electrode 

    Clark, Steve J.; Wang, Da; Armstrong, A. Robert; Bruce, Peter G. (2016-03-21) - Journal article
    Graphite, the dominant anode in rechargeable lithium batteries, operates at similar to ~0.1V versus Li+/Li and can result in lithium plating on the graphite surface, raising safety concerns. Titanates, for example, Li4Ti5O12, ...
  • Na2Fe(C2O4)F2 : a new iron-based polyoxyanion cathode for Li/Na ion batteries 

    Yao, Wenjiao; Sougrati, Moulay-Tahar; Hoang, Khang; Hui, Jianing; Lightfoot, Philip; Armstrong, A. Robert (2017-03-14) - Journal article
    A new mixed anion compound, Na2Fe(C2O4)F2 has been prepared by hydrothermal synthesis. The crystal structure exhibits infinite chains of corner-linked FeII-centred octahedra, with coordination composed of both oxalate and ...
  • Nanostructured TiO2(B): the effect of size and shape on anode properties for Li-ion batteries 

    Liu, Zheng; Andreev, Yuri G.; Armstrong, A. Robert; Brutti, Sergio; Ren, Yu; Bruce, Peter G. (2013-06) - Journal item
    Reducing the dimensions of electrode materials from the micron to the nanoscale can have a profound influence on their properties and hence on the performance of electrochemical devices, e.g. Li-ion batteries, that employ ...
  • A novel copper oxalate, Na2Cu(C2O4)2 

    Yao, Wenjiao; Armstrong, A. Robert; Lightfoot, Philip (2016-12-05) - Journal article
    A novel copper oxalate Na2Cu(C2O4)2 was synthesized through a hydrothermal method and characterized by single-crystal X-ray diffraction. It crystallizes in monoclinic system, P21/n space group with a = 72578(3) Å, b = ...
