Unit Cell and Battery Cell Including the Same

A method of fabricating a unit cell, comprising:

• applying a first adhesive to either or both of (i) a first face of an electrode or (ii) an abutment region of a first separator;
• applying the first adhesive to either or both of (i) a second face of the electrode or (ii) an abutment region of a second separator, the second face of the electrode being on an opposite side of the electrode from the first face;
• applying a second adhesive to either or both of (i) a peripheral region of the first separator or (ii) a peripheral region of the second separator;
• and
• forming at least a portion of a stack by stacking the electrode between the first separator and the second separator such that the first face of the electrode abuts the abutment region of the first separator and the second face of the electrode abuts the abutment region of the second separator, the stack being formed such the peripheral region of each of the first and second separators extends outwardly beyond an edge of the electrode, the peripheral regions of each of the first and second separators opposing one another without the electrode interposed therebetween;
• wherein the first adhesive is configured to have a degree of dispersion in an electrolyte that is greater than a degree of dispersion of the second adhesive in the electrolyte.
