  • Patent number: 10906810
    Abstract: High quality, catalyst-free boron nitride nanotubes (BNNTs) that are long, flexible, have few wall molecules and few defects in the crystalline structure, can be efficiently produced by a process driven primarily by Direct Induction. Secondary Direct Induction coils, Direct Current heaters, lasers, and electric arcs can provide additional heating to tailor the processes and enhance the quality of the BNNTs while reducing impurities. Heating the initial boron feed stock to temperatures causing it to act as an electrical conductor can be achieved by including refractory metals in the initial boron feed stock, and providing additional heat via lasers or electric arcs. Direct Induction processes may be energy efficient and sustainable for indefinite period of time. Careful heat and gas flow profile management may be used to enhance production of high quality BNNT at significant production rates.

  • Patent number: 10177380
    Abstract: The present invention relates to an anode active material including natural graphite and mosaic coke-based artificial graphite, and a lithium secondary battery including the same. According to an embodiment of the present invention, an anode active material including natural graphite and mosaic coke-based artificial graphite is used, when applied to a lithium secondary battery, intercalation and deintercalation of lithium ions is more facilitated and conductivity of an electrode is improved even if no or little conductive material is used. Furthermore, the increase in conductivity can lead to not only a further improvement in rate performance of a lithium secondary battery but also a reduction in interfacial resistance.

  • Patent number: 10096428
    Abstract: At least one of an aqueous solution A containing lithium, an aqueous solution B containing iron, manganese, cobalt, or nickel, and an aqueous solution C containing a phosphoric acid includes graphene oxide. The aqueous solution A is dripped into the aqueous solution C, so that a mixed solution E including a precipitate D is prepared. The mixed solution E is dripped into the aqueous solution B, so that a mixed solution G including a precipitate F is prepared. The mixed solution G is subjected to heat treatment in a pressurized atmosphere, so that a mixed solution H is prepared, and the mixed solution H is then filtered. Thus, particles of a compound containing lithium and oxygen which have a small size are obtained.
