Abstract

Provided is an electrode assembly for a secondary battery, including: one or more first electrode plates: one or more second electrode plates stacked alternately with the first electrode plates; first electrode taps extended from the first electrode plates, respectively; second electrode taps extended from the second electrode plates, respectively; a separator disposed between the first electrode plates and the second electrode plates; and a spacer part formed on lateral surfaces formed in a stacking direction of edges of the first electrode plates and the second electrode plates, so that, by including the spacer part, internal short circuits can be prevented and insertability into a pouch type battery case can be improved, thereby improving stability, reliability, and productivity thereof.

Claims (10)

1. An electrode assembly for a secondary battery, comprising:

one or more first electrode plates:

one or more second electrode plates stacked alternately with the first electrode plates;

first electrode taps extended from the first electrode plates, respectively;

second electrode taps extended from the second electrode plates, respectively;

a separator disposed between the first electrode plates and the second electrode plates; and

a spacer part integrally formed by coating a sealing memeber on lateral surfaces formed in a stacking direction of edges of the first electrode plates and the second electrode plates.

2. The electrode assembly of claim 1 , wherein the spacer part is formed on one lateral surface where the first electrode taps and the second electrode taps are formed, and the other lateral surface facing one lateral surface where the first electrode taps and the second electrode taps are formed.

3. The electrode assembly of claim 2 , wherein the spacer part is formed on the whole of each of the lateral surfaces formed in a stacking direction of the edges of the first electrode plates and the second electrode plates.

4. The electrode assembly of claim 2 , wherein the spacer part is formed on a center portion or both sides of each of the lateral surfaces formed in a stacking direction of the edges of the first electrode plates and the second electrode plates.
