20100136431	ANODE ACTIVE MATERIAL, ANODE INCLUDING THE ANODE ACTIVE MATERIAL, METHOD OF MANUFACTURING THE ANODE, AND LITHIUM BATTERY INCLUDING THE ANODE - An anode active material for lithium batteries, an anode including the anode active material, a method of manufacturing the anode, and a lithium battery including the anode. The anode active material includes secondary particles formed of agglomerated primary nanoparticles. The primary nanoparticles include a non-carbonaceous material bound with hollow carbon nanofibers. The anode includes the anode active material and a polymeric binder having an electron donor group.	06-03-2010
20100159331	NEGATIVE ACTIVE MATERIAL, NEGATIVE ELECTRODE INCLUDING THE SAME, METHOD OF MANUFACTURING THE NEGATIVE ELECTRODE, AND LITHIUM BATTERY INCLUDING THE NEGATIVE ELECTRODE - A negative active material, a negative electrode including the negative active material, a method of manufacturing the negative electrode, and a lithium battery including the negative electrode. The negative active material includes a composite including a non-carbonaceous material, carbon nanotubes (CNTs), and carbon nanoparticles. The carbon nanoparticles are formed by carbonizing a polymer of carbonizable monomers.	06-24-2010
20100261050	COMPOSITE ANODE ACTIVE MATERIAL, METHOD OF PREPARING THE COMPOSITE ANODE ACTIVE MATERIAL, AND LITHIUM BATTERY INCLUDING THE COMPOSITE ANODE ACTIVE MATERIAL - A composite anode active material, a method of preparing the composite anode active material, and a lithium battery including the lithium battery. According to the method of preparing the composite anode active material, carbon nanotubes are formed on a Si particle without a separate operation of applying a catalyst. Furthermore, high adherence is provided between the Si particle and carbon nanotubes, and therefore the composite anode active material is used as an anode material of the lithium battery.	10-14-2010

20100193731	COMPOSITE ANODE ACTIVE MATERIAL, ANODE INCLUDING THE COMPOSITE ANODE ACTIVE MATERIAL, LITHIUM BATTERY INCLUDING THE ANODE, AND METHOD OF PREPARING THE COMPOSITE ANODE ACTIVE MATERIAL - A composite anode active material including metal core particles and carbon nanotubes that are covalently bound to the metal core particles, an anode including the composite anode active material, a lithium battery employing the anode, and a method of preparing the composite anode active material.	08-05-2010
20100255402	Carbon nanotubes, supported catalyst including the same, and fuel cell using the supported catalyst - A carbon nanotube, a method of preparing the same, a supported catalyst including the same, and a fuel cell using the supported catalyst are provided. The method of preparing the carbon nanotube includes: depositing a metal catalyst in single wall nanotubes and growing multi wall nanotubes over the single wall nanotubes using the metal catalyst. The carbon nanotubes of the present invention have satisfactory specific surface area and low surface resistance. Thus, the carbon nanotubes perform remarkably better than a conventional catalyst carrier. Accordingly, the carbon nanotubes, when used as a catalyst carrier of an electrode for a fuel cell, can improve the electrical conductivity of the fuel cell. In addition, a fuel cell employing the electrode has excellent efficiency and overall performance.	10-07-2010
