  • Publication number: 20180111108
    Abstract: A method for producing conductive carbon coated particles of an at least partially lithiated electroactive core material comprises the step of premixing an oxidant electroactive material with a metallated reductant followed by chemically reacting the oxidant electroactive material with the metallated reductant, said reductant being a coating precursor, said metal being at least one alkaline and/or at least one alkaline earth metal, and said chemically reacting being performed under conditions allowing reduction and metallation of the electroactive material via insertion/intercalation of the alkaline metal cation(s) and/or the alkaline earth metal cation(s) and coating formation via a polymerisation reaction like polyanionic or radicalic polymerisation of the reductant.

  • Patent number: 9761867
    Abstract: Nanocomposits of conductive, nanoparticulate polymer and electronically active material, in particular PEDOT and LiFePO4, were found to be significantly better compared to bare and carbon coated LiFePO4 in carbon black and graphite filled non conducting binder. The conductive polymer containing composite outperformed the other two samples. The performance of PEDOT composite was especially better in the high current regime with capacity retention of 82% after 200 cycles. Hence an electrode based on composite made of conductive, nanoparticulate polymer and electronically active material, in particular LiFePO4 and PEDOT nanostubs, with its higher energy density and increased resistance to harsh charging regimes proved to dramatically extend the high power applicability of materials such as LiFePO4.

  • Patent number: 9548494
    Abstract: A method for producing colloidal graphene dispersions comprises the steps of: (i) stirring graphite oxide in an aqueous dispersion medium to form a dispersion; (ii) determining if the dispersion is optically clear in a light microscope at 1000 fold magnification after 1 to 5 hours of stirring, and, if not clear, removing any undissolved impurities in the dispersion, in order to form a colloidal graphene oxide dispersion, or a multi-graphene oxide dispersion, that is optically clear in a light microscope at 1000 fold magnification; and (iii) thermally reducing the graphene oxide, or multi-graphene oxide, in dispersion in the aqueous dispersion medium at a temperature between 120° C. and 170° C. under pressure in order to ensure that the dispersion medium is not evaporated to form a stable colloidal graphene dispersion or a stable multi-graphene dispersion.
