Abstract

Disclosed herein is an anode for a secondary battery manufactured thereby. The anode for a secondary battery includes a first adhesive member and a second adhesive member to which a plurality of electrolytes are fused, a first case configured to be fused to the first adhesive member, and a second case configured to be fused to the second adhesive member and the first case and into which an anode active material and a liquid electrolyte are injected. The anode has an effect of maximizing a reaction area because an electrolyte is exposed at both surfaces of the anode for a secondary battery.

First claim

What is claimed is:

1. An anode for a second battery, comprising:
a first adhesive member and a second adhesive member to which a plurality of electrolytes are fused;
a first case configured to be fused to the first adhesive member; and
a second case configured to be fused to the second adhesive member and the first case and into which an anode active material and a liquid electrolyte are injected.

2. The anode of claim 1 , further comprising an anode current collector provided inside the second case and having a portion exposed to the outside of the second case to form an external connection terminal.

3. The anode of claim 1 , wherein the first adhesive member and the second adhesive member have sheet shapes.

4. The anode of claim 1 , wherein each of the first adhesive member and the second adhesive member includes a plurality of openings having edges fused to the plurality of electrolytes.

5. The anode of claim 1 , wherein each of the first case and the second case includes a plurality of openings configured to expose portions of the plurality of electrolytes to the outside of the anode for a secondary battery.

6. The anode of claim 5 , wherein the plurality of openings are disposed to face each other at the first case and the second case.

7. The anode of claim 5 , wherein each of the first case and the second case includes stepped levels on which the plurality of electrolytes are seated and which are formed along edges of the plurality of openings.
