Abstract
Methods for making carbon materials are provided. In at least one specific embodiment, the method can include combining one or more polymer precursors with one or more liquids to produce a mixture. The mixture can be an emulsion, dispersion, or a suspension. The liquid can include hexane, pentane, cyclopentane, benzene, toluene, o-xylene, m-xylene, p-xylene, diethyl ether, ethylmethylketone, dichloromethane, tetrahydrofuran, mineral oils, paraffin oils, vegetable derived oils, or any mixture thereof. The method can also include aging the mixture at a temperature and time sufficient for the polymer precursor to react and form polymer gel particles having a volume average particle size (Dv,50) of the polymer particles in gel form greater than or equal to 1 mm. The method can also include heating the polymer gel particles to produce a carbon material.
