  • Publication number: 20130157139
    Abstract: The disclosure relates to an anode active material, a non-aqueous lithium secondary battery, and a manufacturing method thereof. The anode active material of this disclosure comprises a carbon-based material, and a coating film formed on the surface of the carbon-based material by performing heat treatment using an ammonia-based compound. The coating film may be formed on the surface of the carbon-based material through a thermal decomposition method using 10% or less by weight of the ammonia-based compound with respect to the carbon-based material. Since the surface of the carbon-based material is thermally treated using the ammonia-based compound, side reaction of the carbon-based material with an electrolyte at the surface thereof can be suppressed and structural stability can be enhanced, thereby improving battery lifespan and high-rate capability of a non-aqueous lithium secondary battery.

    Abstract: Modified natural graphite particles intended for forming a negative electrode material for a nonaqueous electrolyte secondary battery are characterized by having a circularity of at least 0.93 and at most 1.0 and a surface roughness of at most 1.5% with respect to the length of the particles. These modified natural graphite particles are obtained by a manufacturing method including a step of applying an impact force to natural graphite particles for pulverization and spheroidization to obtain intermediate particles having a circularity of at least 0.93 and at most 1.0, and a step of carrying out surface smoothing of the resulting intermediate particles by mechanical grinding treatment to obtain the modified natural graphite particles.

  • Patent number: 8409768
    Abstract: Growing spin-capable multi-walled carbon nanotube (MWCNT) forests in a repeatable fashion will become possible through understanding the critical factors affecting the forest growth. Here we show that the spinning capability depends on the alignment of adjacent MWCNTs in the forest which in turn results from the synergistic combination of a high areal density of MWCNTs and short distance between the MWCNTs. This can be realized by starting with both the proper Fe nanoparticle size and density which strongly depend on the sheet resistance of the catalyst film. Simple measurement of the sheet resistance can allow one to reliably predict the growth of spin-capable forests. The properties of pulled MWCNTs sheets reflect that there is a relationship between their electrical resistance and optical transmittance. Overlaying either 3, 5, or 10 sheets pulled out from a single forest produces much more repeatable characteristics.

    Abstract: The present disclosure relates to anode materials having high surface areas and improved cycle performance made by surface treatments of spheroidized graphite powders. The surface treatments provide a high surface area protective coating over the spheroidized graphite powder. The anodes made according to the disclosed embodiments have improved cycle life and long term high temperature storage performance. In the disclosed embodiments, a spheroidized graphite powder is coated with a high surface area protective coating. The high surface area protective coating improves the performance and durability of an anode made from disclosed 200 material. The high surface area protective coating can include polymers, metal compounds and/or hard carbon. Further, in some embodiments, a protective coating, that may or may not have a high surface area but does have increased durability, can be formed by heat treating the spheroidized graphite in oxidizing or inert atmospheres.
