US 2009/0152509 A1 · INKJET PRINTABLE ELECTRODE COMPOSITION, ELECTRODE INCLUDING THE SAME, AND SECONDARY BATTERY INCLUDING THE ELECTRODE

Abstract

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.
