The present invention is related to an electrode and a method for preparing the same, and is particularly related to an electrode that has an intricate structure of active material layer, conductive material layer, or mixture layer of active material and conductive material that displays superior electrochemical properties despite being thin, and a method for preparing an electrode using the coating method of SIC.

Electrode and method for preparing the same using substrate induced coagulation (SIC)

Disclosed is a method for producing surface-modified materials, such as core-shell materials with the core and the shell(s) being different distinct phases, or materials with a concentration gradient of one or more dopant or substituent element(s) from the surface to the bulk. The method comprises (i) treating the bulk of material with a solution containing a first solvent and at least one flocculant comprising a soluble polymer so that the flocculant adheres to the bulk; (ii) subsequently contacting the flocculant-treated bulk of step (i) with a dispersion containing a second solvent and the particulate solid particles to deposit the particulate solid particles on the flocculant-treated bulk; and (iii) subsequently treating the resultant of step (ii) with heat. This method can in particular be applied to produce surface-modified cathode materials for Li batteries with improved performance.
