ELECTRODE ASSEMBLY HAVING NOVEL STRUCTURE, AND BATTERY CELL COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2013/137575

Kind Code:

A1

Abstract:

The present invention provides an electrode assembly having a structure in which a continuous separation film having one bi-cell and one or more monocells positioned thereon is wrapped, wherein the bi-cell is a unit cell having identical types of electrodes on both surfaces and is positioned at the starting area for wrapping of the separation film, the unit cell having a structure in which one or more anodes, one or more cathodes, and a separation membrane interposed therebetween are stacked, and the monocell is a unit cell having different types of electrodes on both surfaces and a length of n times (here, n is an integer equal to or greater than 2) the width (w) of the bi-cell, and is distanced from the bi-cell by a distance corresponding to the width(w) of the bi-cell and is arranged so that the poles opposite to both poles of the bi-cell are directed to the upper surface, and is bent, in a stacked state, by a unit length corresponding to the width(w) of the bi-cell.
