摘要：

The purpose of this work was to economically prepare large electrodes (32 cm(2)) in order to assemble mono-cell supercapacitors (100 cm(3)) of 250 F and to reach powers in the range of 120-130 W (2 V/cell) with the structure selected. We have reached more than 20 F/cm(3) of electrode, with a time constant of a few seconds (close to 2 s) and reached powers compatible with starting applications. (C) 1999 Elsevier Science S.A.
