{"product_id":"cscspcm","title":"Porous Carbon Microsphere (500 um, 950 m2\/g) for Supercapacitor and Catalyst Support, 10-50 g\/bottle, CSCSPCM","description":"\u003cp\u003eA porous carbon microsphere (PCM) with an average particle diameter of 500 um and a specific surface area of 950 m2\/g occupies a unique design space in electrochemical energy storage and catalysis. While high-surface-area carbons are often supplied as ultra-fine nanoparticles or powders that present handling and agglomeration challenges, a micron-scale spherical architecture (500 um) introduces distinct hydrodynamic, packing, and mass-transport advantages.\u003c\/p\u003e\n\u003cp\u003eFor supercapacitor applications it shows the following advantages: (1) \u003cstrong\u003eHigh Electric Double-Layer Capacitance\u003c\/strong\u003e: The 950 m2\/g surface area allows for extensive electrostatic charge storage via reversible ion adsorption\/desorption at the electrode\/electrolyte interface. In typical organic (e.g., 1 M Et4NBF4 in PC\/DMC) or ionic liquid electrolytes, carbons in this surface area bracket achieve specific capacitances of 120–180 F\/g. (2) \u003cstrong\u003eHigh Tap Density and Volumetric Performance\u003c\/strong\u003e: Fine carbon powders suffer from low tap densities, resulting in poor volumetric capacitance. The micron-scale spherical morphology improves powder flowability and packing efficiency, yielding higher volumetric energy density in coin or pouch cells. (3) \u003cstrong\u003eRate Capability\u003c\/strong\u003e: The open interparticle channels between the 500 um spheres facilitate rapid ionic transport during high-current-density charge\/discharge cycles (~ 10 A\/g), minimizing equivalent series resistance (ESR).\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAs for catalyst supports, its main features are: (1) \u003cstrong\u003eDispersion of Active Sites\u003c\/strong\u003e: The 950 m2\/g area provides abundant anchoring sites for metal nanoparticles (e.g., Pt, Pd, RuO2), single-atom catalysts (SACs), or metal-organic framework (MOF) derivatives, preventing particle agglomeration and sintering during high-temperature treatments or catalytic reactions. (2) \u003cstrong\u003eFlow-Through and Packed-Bed Reactor Suitability\u003c\/strong\u003e: In heterogeneous electrocatalysis (such as electrochemical CO2 reduction, oxygen reduction reaction [ORR], water splitting, or organic electrosynthesis), fine nanoparticle catalysts create extreme pressure drops in flow cells or microfluidic reactors. The 500 um microsphere size allows them to function as free-flowing granules suitable for packed-bed reactors, fluidized beds, or compartmentalized flow-cell electrodes without clogging or inducing high hydraulic resistance. (3) \u003cstrong\u003eMechanical Robustness\u003c\/strong\u003e: The spherical form factor distributes mechanical stress evenly, resisting degradation or pulverization under mechanical compression in zero-gap flow cell configurations.\u003c\/p\u003e\n\u003ctable style=\"width: 108.74%; height: 163.575px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 43.575px;\"\u003e\n\u003ctd style=\"width: 22.3514%; height: 43.575px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 77.4873%; height: 43.575px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSCSPCM (C-SCS-PCM)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 22.3514%; height: 39.2px;\"\u003e\u003cem\u003eAverage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 77.4873%; height: 39.2px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e~500 um\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 24.3125px;\"\u003e\n\u003ctd style=\"width: 22.3514%; height: 24.3125px;\"\u003e\u003cem\u003eSpecific Surface Area (BET)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 77.4873%; height: 24.3125px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e950 m2\/g\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 22.3514%; height: 35.6px;\"\u003e\u003cem\u003eBulk Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 77.4873%; height: 35.6px;\"\u003e\n\u003cp\u003e430-450 g\/L\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20.8875px;\"\u003e\n\u003ctd style=\"width: 22.3514%; height: 20.8875px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 77.4873%; height: 20.8875px;\"\u003e10 g, 20 g, and 50 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the porous carbon microsphere powder in a dry place. \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\/S0013468615008245\"\u003eR.
