| 429143000 | Ribs or projections attached to sheet material | 17 |
| 20100323230 | SEPARATOR FOR PROGRESSING UNITED FORCE TO ELECTRODE AND ELECTROCHEMICAL CONTAINING THE SAME - A separator includes a porous substrate having a plurality of pores; a porous coating layer formed on at least one surface of the porous substrate and made of a mixture of a plurality of inorganic particles and a binder polymer; and a dot pattern layer formed on a surface of the porous coating layer and having a plurality of dots made of polymer and arranged at predetermined intervals. The separator may control short-circuit between positive and negative electrodes though an electrochemical device is overheated. Also, a united force to an electrode is enhanced due to the polymer dot pattern layer, thereby preventing the electrode and the separator from being separated. Accordingly, inorganic particles of the porous coating layer formed on the porous substrate are not separated, thereby improving stability of an electrochemical device. | 12-23-2010 |
