USE - Conductive adhesive used for preparing electrode (claimed). ADVANTAGE - Conductive adhesive reduces the floating phenomenon and the gap between the electrode interfaces and electrode resistance of the electrode is reduced to increase the storage capacity. DETAILED DESCRIPTION - Conductive adhesive comprises 0.5 to 20 wt.% graphene, 0.1 to 5 wt.% silver coated copper, potassium alginate or ammonium alginate or propylene glycol alginate, 1 to 15% binder, which is oxalic acid, malonic acid, malic acid, tartaric acid, malonic acid, citric acid, adipic acid, maleic acid, pyromellitic acid, phthalic acid, and 1 to 15wt.% crosslinking agent, which is organic acid, which are trimellitic acid, nonanoic acid, and polybasic acid of succinic acid, and 50 to 96wt.% distilled water at an ultra-high temperature of 140 degrees C or higher. The silver-coated copper is prepared by mixing copper powder in a mixed solvent prepared by mixing water and ethanol in a weight ratio of 1: 1. The oxide film of the copper surface is removed by solvent heat treatment at 75 to 85 degrees C for 20 to 30 hours. The copper powder from which the oxide film is removed is dispersed in a ammonium sulfate solution having a weight of 100 to 150 times and stirred for 5 to 15 minutes. Then, the pH is adjusted to 10 to 12 using ammonium hydroxide. C4H4O6KNa solution is added as a reducing agent in a nitrogen atmosphere and AgNO3 solution of 0.1 to 2M concentration is dropped on the surface of the copper for 5 to 10 minutes in order to coat silver on the copper surface. An INDEPENDENT CLAIM is included for a method for preparing electrodes using adhesive, which involves: (A) using methane gas as a carbon precursor; (B) synthesizing graphene is synthesized at a high temperature of 1,000 degrees C and a high pressure of 10-3 torr; (C) preparing coating of copper is prepared; (D) using 0.5 to 20 wt.% graphene, 0.1-5 wt.% coated copper, 1 to 15 wt.% binder and 1 to 15 wt.% crosslinking agent and distilled water; (E) preparing conductive adhesive agent by applying the conductive adhesive agent on the surface of a carbon sheet and heating and drying the conductive adhesive agent layer to form a conductive adhesive agent layer having a dry thickness of 0.2 to 50 mu m; (F) applying an activated carbon slurry, which is an electrode material; (G) pressing to improve the homogeneity of the electrode, where activated carbon slurry contains 87 wt.% activated carbon having a size of 10 mu m, 5 wt.% carbon black as a conductive material, 3 wt.% carboxymethyl cellulose (CMC), 4 wt.% polytetrafluoroethylene solution (PTFE solution) having a solid content of 60%, and 1 wt.% polyvinylpyrrolidone (PVP) as a binder; and (H) stirring mixture and mixing in a planetary disperser registered mixer while distilled water is added until the solid content is the mixture becomes 32%.
