"Electrochemical Device Having Different Kinds Of Separators"
Abstract: An electrochemical device includes a plurality of unit cells, each having a first separator and a cathode and an anode positioned at both sides of the first separator, and a continuous single second separator interposed between adjacent unit cells in correspondence with each other in a laminated pattern and arranged to surround each unit cell. The first separator includes a heat-resisting porous substrate having a melt point of 200℃ or above and a first porous coating layer formed on at least one surface of the heat-resisting porous substrate and made of a mixture of a plurality of inorganic particles and a binder polymer. The second separator includes a polyolefin porous substrate and a second porous coating layer formed on at least one surface of the polyolefin porous substrate and made of a mixture of a plurality of inorganic particles and a binder polymer.
