Abstract
Carbon particles are disclosed, as well as methods and systems for forming the particles. In one embodiment, the system may include a receiving vessel configured to receive a liquid carbon precursor and at least one orifice at a bottom of the receiving vessel and configured to release droplets of the precursor. A cooling vessel may be positioned below the receiving vessel to receive the droplets and configured to hold a coolant for solidifying the droplets into carbon precursor particles. The method may include introducing a liquid carbon precursor into a tank having a plurality of orifices defined therein such that droplets of the precursor are released from the orifices and solidifying the droplets in a cooling vessel positioned to receive the droplets from the orifices. The method may then include carbonizing the solidified droplets to form carbon particles. The particles may be solid or hollow.
