  • Tin based anode material for a rechargeable battery and preparation method
    Patent number: 10573887
    Abstract: A tin based anode material for a rechargeable battery comprises nanoparticles of composition SnMxOy wherein M is a further element selected from the group 5 consisting of Ni, Cu, In, Al, Ge, Pb, Bi, Sb, Fe, Co, Ga, with 0?x?0.5 and 0?y?2+2x. The nanoparticles form a substantially monodisperse ensemble with an average size not exceeding 30 nm and a size deviation not exceeding 15%, the nanoparticles optionally being coated with a capping species. A method for preparing the tin based anode material is carried out in situ in a non-aqueous solvent and starts by reacting a tin salt and an organometallic amide reactant and oleylamine.
    Type: Grant
    Filed: November 28, 2013
    Date of Patent: February 25, 2020
    Assignee: Belenos Clean Power Holding AG
    Inventors: Maksym Kovalenko, Maryna Bodnarchuk, Kostiantyn Kravchyk
  • Antimony based anode material for rechargeable batteries and preparation method
    Patent number: 9923202
    Abstract: An antimony based anode material for a rechargeable battery includes nanoparticles of composition SbMxOy, where M is an element selected from the group consisting of Sn, Ni, Cu, In, Al, Ge, Pb, Bi, Fe, Co, and Ga, with 0?x<2 and 0?y?2.5+2x. The nanoparticles form a substantially monodisperse ensemble with an average size not exceeding a value of 30 nm and by a size deviation not exceeding 15%. A method for preparing the antimony based anode material is carried out in situ in a non-aqueous solvent and starts by reacting an antimony salt and an organometallic amide reactant and oleylamine.
