An active carbon molded body that comprises a plurality of active carbon granules that are formed from aggregates of active carbon particles. The active carbon granules include a fibrous granulation binder. The active carbon molded body is formed as a result of the plurality of active carbon granules being aggregated by means of the fibrous granulation binder in the active carbon granules. The present invention is also an active carbon molded body production method in which active carbon granules that have been formed by aggregating active carbon particles by means of a fibrous binder are molded by simultaneous application of heat and pressure without separate addition of a molding binder. The present invention thereby provides: an active carbon molded body that has high purification capacity and good production efficiency; and a production method for the active carbon molded body.

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.

The present invention discloses a method for preventing shedding of activated carbon (108) when utilized in battery electrode, the method comprises dissolving at least one binder (102) with a solvent (104) to form a solution (106). A slurry (110) is prepared by adding activated carbon (108) to the formed solution (106). The solvent (104) is evaporated by drying the slurry (110). The dried slurry is heated to a predefined temperature for a predefined duration to bind the activated carbon (108) particles together and reduce shedding during usage of activated carbon in battery electrode. The dried slurry is further heated to the predefined temperature higher than what is used for binding activated carbon particles together for a further predefined duration to remove unwanted functional groups leading to parasitic reaction. Thereafter, the processed bonded activated carbon (112) is collected to be used in the battery electrode.
