Abstract

Porous vitreous carbon with good electrical and mechanical properties as well as large double-layer capacitance can be produced by hardening and pyrolysis of thermosetting carbonizable resins including about 1 to 10 weight-percent of a salt of a fatty acid having about 10 to 20 carbon atoms which is soluble in the resin and can be volatilized without residue.
