{"product_id":"csomccmk8","title":"Ordered Mesoporous Carbon (CMK-8) with 3D Cubic Structure for Supercapacitor, 1 g\/bottle, CSOMCCMK8","description":"\u003cp\u003eCMK-8 is a three-dimensional (3D) cubic ordered mesoporous carbon that offers significant advantages over the more common 2D hexagonal CMK-3. While CMK-3 consists of parallel rods, CMK-8 features a bicontinuous, interconnected network of pores, which is a game-changer for high-power supercapacitor performance.\u003c\/p\u003e\n\u003cp\u003eCMK-8 is synthesized via the nanocasting method using KIT-6 silica as a hard template. (1) \u003cstrong\u003e3D Interconnectivity\u003c\/strong\u003e: Unlike CMK-3’s independent channels, CMK-8 has a cubic Ia3d symmetry. This means its pores are interconnected in all three dimensions, creating a \"gyroid\" structure that prevents the \"bottleneck\" effect. (2) \u003cstrong\u003ePore Characteristics\u003c\/strong\u003e: It typically has a pore diameter ranging from 3.2 to 6.6 nm and a specific surface area exceeding 500–1,000 m}^2\/g (depending on the carbonization temperature). (3) \u003cstrong\u003eMass Transfer\u003c\/strong\u003e: The 3D cubic structure provides superior mass transfer characteristics because electrolyte ions have multiple paths to travel, reducing the risk of a single channel getting blocked.\u003c\/p\u003e\n\u003cp\u003eThe reasons for CMK-8 widely used in supercapacitor: (1) \u003cstrong\u003eLower ESR\u003c\/strong\u003e: The 3D interconnected framework ensures a continuous electronic pathway, resulting in very low Equivalent Series Resistance (ESR). (2) \u003cstrong\u003eVolumetric Efficiency\u003c\/strong\u003e: Because the structure is highly ordered and dense, it often yields a higher volumetric capacitance (F\/cm^3) than \"fluffy\" amorphous carbons. (3) \u003cstrong\u003eBulky Ion Compatibility\u003c\/strong\u003e: The large mesopores (\u0026gt;3 nm) make it ideal for Ionic Liquids and large organic electrolytes, which would otherwise get stuck in standard microporous activated carbon (like YP-50F).\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 297.275px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 41.175px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 41.175px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 41.175px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSOMCCMK8 (C-S-OMCCMK8)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.9px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 22.9px;\"\u003e\u003cem\u003eSpecific Surface Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 22.9px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e~1500 m2\/g\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 35.6px;\"\u003e\u003cem\u003ePore Connectivity \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 35.6px;\"\u003e\n\u003cp\u003eBicontinuous (3D), 1-2 um long\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 35.6px;\"\u003e\u003cem\u003ePore Volume\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 35.6px;\"\u003e\n\u003cp\u003e0.8-1.3 cm3\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 35.6px;\"\u003e\u003cem\u003eMesopore Diameter\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 35.6px;\"\u003e\n\u003cp\u003e~3.5-6.5 nm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 71.2px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 71.2px;\"\u003e\u003cem\u003eSpecific Capacitance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 71.2px;\"\u003e\n\u003cp\u003e~180 F\/g (aqueous electrolyte, eg: 2M KOH)\u003c\/p\u003e\n\u003cp\u003e~50 F\/g (organic electrolyte, eg: TEABF4)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 19.6px;\"\u003e1 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the CMK-8 powder in a dry place (glovebox is the best option). \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cspan\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0378775311015163\"\u003eJ.
