Porous active carbon prepared from aromatic condensation polymer and use thereof in electrodes for electrochemical cells

摘要

An insoluble and infusible substrate with a polyacentype skeletal structure having a hydrogen/carbon atomic ratio of from 0.05 to 0.60 and containing open pores having an average diameter of not more than 10 micrometers, said substrate being a heat-treated product of an aromatic condensation polymer consisting of carbon, hydrogen and oxygen. The substrate, when doped with a dopant, gives an electrically conductive material. When having a specific surface area of at elast 600 m<2>/g, the substrate is especially useful as an electrode of an organic cell.
