Patent number: 8481196Abstract: Disclosed herein is an electrochemical cell constructed in a structure in which a plurality of full cells or bicells, as unit cells, are folded by a separation film formed in the shape of a long sheet, and separators of the unit cells are secured to the separation film by thermal welding. The electrochemical cell according to the present invention has the effect of preventing the electrodes of the stacked electrodes from being separated from the separation film or from being twisted due to external impacts and vibrations, thereby restraining the electrochemical cell from generating heat or catching fire. Furthermore, the structural stability of the electrochemical cell is maintained even when the temperature of the electrochemical cell is increased, or the volume of the electrochemical cell is increased due to the generation of gas.Type: GrantFiled: February 12, 2007Date of Patent: July 9, 2013Assignee: LG Chem, Ltd.Inventors: Ji Heon Ryu, Jaepil Lee, Jeong Hee Choi, Min Su Kim, Youngjoon Shin
