  • Patent number: 12142754
    Abstract: A method of fabricating nanocomposite anode material embodying a lithium titanate (LTO)-multi-walled carbon nanotube (MWNT) composite intended for use in a lithium-ion battery includes providing multi-walled carbon nanotube (MWNTs), including nanotube surfaces, onto which functional oxygenated carboxylic acid moieties are arranged, generating 3D flower-like, lithium titanate (LTO) microspheres, including thin nanosheets and anchoring the acid-functionalized MWNTs onto surfaces of the 3D LTO microspheres by ?-? interaction strategy to realize the nanocomposite anode material.

  • Publication number: 20240145679
    Abstract: A method of preparing a composition for use as a cathode that combines two different cathode materials is disclosed. When utilized in a battery, one cathode material is rechargeable, and the second cathode material has a high capacity with a lower voltage than the first cathode material. The active materials may be combined in several fashions including mixing, layering, deposition, coating, and/or patterning. Such batteries can be tested repeatedly over a specific voltage range and provide high capacity under full discharge at deployment.

  • Patent number: 11532806
    Abstract: Preparation, characterization, and an electrochemical study of Mg0.1V2O5 prepared by a novel sol-gel method with no high-temperature post-processing are disclosed. Cyclic voltammetry showed the material to be quasi-reversible, with improved kinetics in an acetonitrile-, relative to a carbonate-, based electrolyte. Galvanostatic test data under a C/10 discharge showed a delivered capacity >250 mAh/g over several cycles. Based on these results, a magnesium anode battery, as disclosed, would yield an average operating voltage ˜3.2 Volts with an energy density ˜800 mWh/g for the cathode material, making the newly synthesized material a viable cathode material for secondary magnesium batteries.

  • Patent number: 11349117
    Abstract: A method of synthesizing an electrode material for lithium ion batteries from Fe3O4 nanoparticles and multiwalled carbon nanotubes (MWNTs) to yield (Fe3O4-NWNTs) composite heterostructures. The method includes linking the Fe3O4 nanoparticles and multiwalled carbon nanotubes using a ?-? interaction synthesis process to yield the composite heterostructure electrode material. Since Fe3O4 has an intermediate voltage, it can be considered an anode (when paired with a higher voltage material) or a cathode (when paired with a lower voltage material).

  • Publication number: 20210280852
    Abstract: An anode configured for fast charging a lithium-ion battery includes an anode substrate and a coating provided on a surface of the anode substrate for increasing an overpotential of Li metal to inhibit Li metal plating during extreme fast charging a lithium-ion battery fabricated with the anode. The anode is fabricated by a process of applying a coating to the anode substrate surface that comprises a nanolayer of Cu, or a nanolayer of Ni or a composite nanolayer of Cu and Ni.
