| 20090152509 | INKJET PRINTABLE ELECTRODE COMPOSITION, ELECTRODE INCLUDING THE SAME, AND SECONDARY BATTERY INCLUDING THE ELECTRODE - An inkjet printable electrode composition, an electrode including the electrode composition, and a secondary battery including the electrode. The inkjet printable electrode composition includes oxide, a conducting agent, a wetting agent, a binder and an aqueous solvent, in which the viscosity of the binder is in a range of 2 to 20 cps in a 1 wt % aqueous solution of the binder. The inkjet printing electrode composition includes a binder having an appropriate viscosity to allow ink to be easily ejected when the ink is inkjet-printed, and thus, a uniform, thin, and planarized pattern may be formed onto a collector by inkjet printing, without clogging of a nozzle, and thus electrode and secondary battery may be formed at low costs. | 06-18-2009 |

| 20100258761 | ANODE ACTIVE MATERIAL, METHOD OF PREPARING THE SAME, AND ANODE AND LITHIUM BATTERY CONTAINING THE MATERIAL - An anode active material comprises metal core particles, metal nano wires formed on the metal core particles, pores between the metal core particles and the metal nano wires, and a carbon-based coating layer formed on a surface of the metal core particles and metal nano wires. In the anode active material according to the present invention, the metal core particles and metal nano wires are combined to form a single body, and a carbon-based coating layer is formed on the surface of the metal nano wires and metal core particles. Thus, volume changes in the pulverized metal core particles can be effectively buffered during charging and discharging, and the metal core particles are electrically connected through the metal nano wires. As a result, volume changes in the anode active material and degradation of the electrode can be prevented, thereby providing excellent initial charge/discharge efficiency and enhanced charge/discharge capacity. | 10-14-2010 |
