Electrode assembly and method for manufacturing same

1. A method for manufacturing an electrode assembly, the method comprising:

providing a first substrate and a second substrate;

plasma treating the first substrate;

forming an electrode on the first substrate;

thermally compressing the first substrate and the second substrate, with the electrode therebetween; and

patterning a portion of the second substrate to thereby form a through-hole that exposes a portion of a top face of the electrode,

wherein each of the first substrate and the second substrate includes a fluorine-based polymer.

2. The method of claim 1 , wherein the patterning of a portion of the second substrate comprises:

forming a protective layer on the top face of the second substrate;

patterning the protective layer to removing a first region;

etching the second substrate corresponding to a patterned and removed portion of the protective layer; and

removing the protective layer.

3. The method of claim 2 , further comprising forming a contact part in the through-hole, wherein the contact part is composed of a porous conductive material.

4. The method of claim 3 , wherein the contact part is formed by using an electro-deposition method.

5. An electrode assembly comprising:

a first substrate;

an electrode provided on the first substrate;

a second substrate which is thermally compressed to the first substrate, with the electrode therebetween, wherein each of the first substrate and the second substrate includes a fluorine-based polymer; and

a contact part provided on the electrode, wherein the contact part is porous.

6. The electrode assembly of claim 5 , wherein the fluorine-based polymer comprises at least one among polychlorotrifluoroethylene (PCTFE), perfluoro-2,2-dimethyl-1,3-dioxide (PDD), chlorotrifluoroethylene (CTFE), perfluoro-3-butenyl-vinylether (PBVE), perfluoropropylvinylether (PPVE), polytetrafluoroethylene (PTFE), polyvinylidenefluoride (PVDF), polyvinylfluoride (PVF), vinylidene fluoride (VDF), a PBVE-based homopolymer (Cytop™), and a copolymer including at least two thereof.

7. The electrode assembly of claim 6 , wherein the copolymer is a copolymer of ethylene and CTFE (ECTFE), a copolymer of ethylene and TFE (ETFE), a copolymer of fluorinated ethylene and propylene (FEP), hexafluoropropylene (HFP), a copolymer of TFE and PPVE (PFA), a copolymer of TFE and PDD (Teflon™ AF), tetrafluoroethylene (TFE), or poly(TFE-co-HFP-co-VDF) (THV).

8. The electrode assembly of claim 5 , wherein

the second substrate comprises a through-hole that exposes a portion of a top face of the electrode; and

the contact part is provided in the through-hole.

9. The electrode assembly of claim 5 , wherein the chemical bonding comprises a covalent bonding formed by the first radical and the second radical.
