    摘要： 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.

    摘要： A polyurethane binder prepared by a polyurethane compound having double bonds and by crosslinking the polyurethane compounds. The polyurethane binder having double bonds can be dispersed in water with the dispersant including a reactive group such as a carboxyl group, and thus an organic solvent is not required to produce an electrode. The crosslinked polyurethane binder with a high crosslinking density provides an excellent elastic force and binding force, and thus the electrode and the lithium battery employing the polyurethane binder have improved recovery properties and charge/discharge properties.

    摘要： An anode active material and a lithium battery employing the same are provided. In one embodiment of the anode active material, a —(CH2CH2O)— repeating unit is bonded to the surface of metal particles that contain metals that can be alloyed with lithium. The repeating unit prevents reactions between the metal particles and the electrolyte solution. Also, due to its elasticity, the repeating unit absorbs part of the volume expansion of the metal particles. The repeating unit also prevents the metal particles from condensing, thereby enhancing dispersion properties. Accordingly, the inventive anode active material has high capacity and excellent capacity retention during repeated charging and discharging, thereby providing a lithium battery with a long cycle life.
