US 2017/0317375 A1 · ELECTRODE ASSEMBLY

Abstract

An electrode assembly includes: a plurality of first electrodes, each including a first electrode portion having a first active material layer thereon and a first uncoated region electrically connected to the first electrode portion; a separation membrane including a plurality of receiving portions arranged at intervals and respectively accommodating the first electrode portions, the separation membrane being folded so that surfaces of adjacent ones of the receiving portions face each other; and a plurality of second electrodes respectively positioned between adjacent ones of the receiving portions that face each other to overlap a corresponding one of the first electrode portions. The plurality of second electrodes each include a second electrode portion having a second active material layer thereon and a second uncoated region electrically connected to the second electrode portion.
