CMK-3 is the most famous and widely studied Ordered Mesoporous Carbon (OMC). It is essentially the "gold standard" for researchers looking to study how ordered channel structures influence energy storage and ion transport. CMK-3 is a "negative replica" of the silica template SBA-15. Its architecture consists of a 2D hexagonal array of uniform carbon rods held together by thin carbon bridges.
CMK-3 excels in Rate Capability (power density) rather than absolute energy density. Its ordered channels allow ions to move in and out of the electrode with very little resistance. It also serves as a conductive scaffold for high-energy materials, such as (1) PANI/CMK-3: Blending with Polyaniline can increase capacitance to over 480 F/g by adding pseudocapacitance. (2) Metal Oxide Decorating: Depositing MnO2 or CeO2 nanofibers onto the CMK-3 rods. The CMK-3 channels prevent the metal oxides from aggregating and provide a fast path for electrons. (3) SiO2 Dispersion: Recent studies have shown that dispersing small amounts of SiO2 microspheres in the CMK-3 matrix can improve cycle stability and increase capacitance from 133 to 298 F/g in some systems.
