Lithium extraction from orthorhombic lithium manganese oxide and the phase-transformation to spinel

Author: Gummow, RJ ; Liles, DC ; Thackeray, MM Date: Dec 1993 Orthorhombic LiMnO2 products, synthesised by the reaction of gamma-MnO2 and LiOH in argon at 600-620 degrees C using carbon as a reducing agent, have been evaluated as electrode materials in lithium cells. Products that contained a minor ... Read more
Reinvestigation of the structures of lithium-cobalt-oxides with neutron-diffraction data

Author: Gummow, RJ ; Liles, DC ; Thackeray, MM ; David, WIF Date: Nov 1993 The structures of LT-LiCoO2 (synthesised by reaction of Li2CO3 and CoCO3 at 400-degrees-C) and its delithiated product LT-Li0.4CoO2 have been reinvestigated by neutron powder diffraction. Despite an unusually close similarity between diffraction ... Read more
Spinel versus layered structures for lithium cobalt oxide synthesized at 400-degrees-c

Author: Gummow, RJ ; Liles, DC ; Thackeray, MM Date: Mar 1993 Rietveld refinements of X-ray data of LiCoO2 prepared at 400-degrees-C and a chemically-delithiated product Li0.5CoO2 using space group symmetries R3mBAR and Fd3m are reported. Refinements in both R3mBAR (layered-type structure) and Fd3m ... Read more
Structural characterization of Li1.2v3o8 insertion electrodes by single-crystal x-ray-diffraction

Author: De Picciotto, LA ; Adendorff, KT ; Liles, DC ; Thackeray, MM Date: Aug 1993 The crystal structures of Li1.2V3O8 and a lithiated product Li4.0V3O8 have been determined by single-crystal X-ray diffraction methods. The structure refinement of Li1.2V308 confirms that of Li1+xV3O8(x almost-equal-to 0) reported by Wadsley ... Read more
Synthesis and structural characterization of defect spinels in the lithium-manganese-oxide system

Author: Thackeray, MM ; De Kock, A ; David, WIF Date: Oct 1993 Lithium-manganese-oxides prepared at moderate temperatures are under investigation as insertion electrodes for rechargeable lithium batteries. The structures of two defect-spinel compounds synthesized by the reaction of MnCO3 and Li2CO3 at ... Read more
