Abstract

Porous structure of electrode materials was studied and the role played by macroporous in electrodes of model double-layer supercapacitors was experimentally analyzed. It was shown that the excess macropore volume in electrodes has an adverse effect and, on the whole, reduces in a complicated way the specific electrochemical characteristics of these devices. This makes necessary to develop the optimal electrode structure as regards not only nanoporous, but also macroporous structure.
