Claim:
1. A method for producing a porous carbon product, comprising the following method steps: (a) providing a template material in a form of template particles containing macropores, (b) providing a carbon precursor substance, (c) infiltrating the macropores of the template with the precursor substance in melted or dissolved form at a temperature Ta, (d) carbonizing the precursor substance at a temperature Tc, and (e) removing the template to form the porous carbon product, further comprising after step (c) and prior to step (d) subjecting the precursor substance within the macropores of the template to a treatment at a foam formation temperature Tb, wherein at temperature Tb the precursor substance foams during polycondensation and fills the macropores as a fine-pored foam, and wherein after step (d) the fine-pored foam forms a porous carbon structure in which at least 70% of the pores have pore sizes in a range of 10 nm to 150 nm.
