A Cu-porous carbon composite prepared from sawdust was applied to the electrode of the electric double-layer capacitor (EDLC). The Cu-carbon composites were characterized and the properties of the electrode of EDLC were investigated. The carbonaceous material prepared from the sawdust and impregnated with Cu(NO3)2 showed higher capacitance than the commercial activated carbon. The capacitance was dependent on the Cu-content in the composite. The highest capacitance was obtained when Cu-content was 0.086 Cu-g/g.
