{"product_id":"cscsmmhpc13","title":"Meso\/Macroporous Hierarchical-Porous-Carbon (HPC-13) for Supercapacitor and Catalyst Support, 5 g\/bottle, CSCSMMHPC13","description":"\u003cp\u003eHierarchical Porous Carbon (HPC) is an advanced electrode material designed to solve the \"energy-power trade-off\" in supercapacitors. It achieves this by integrating multiple pore sizes—macropores, mesopores, and micropores—into a single carbon architecture.\u003c\/p\u003e\n\u003cp\u003eIn a hierarchical system, each level of porosity serves a distinct electrochemical purpose: (1) \u003cstrong\u003eMacropores (\u0026gt;50 nm)\u003c\/strong\u003e: These serve as ion reservoirs. They minimize the diffusion distance from the bulk electrolyte into the interior of the carbon particle, ensuring the material is always saturated with charge carriers. (2) \u003cstrong\u003eMesopores (2-50 nm)\u003c\/strong\u003e: These act as high-speed transport channels. They connect the reservoirs to the storage sites, allowing ions to move with minimal resistance, which is critical for high power density. (3) \u003cstrong\u003eMicropores (\u0026lt;2 nm)\u003c\/strong\u003e: These provide the massive surface area for charge storage. This is where the electric double-layer (EDL) forms, providing the bulk of the energy density.\u003c\/p\u003e\n\u003cp\u003eCompared to microporous carbon, the HPC has the features of high ion diffusion, excellent rate capability, good electrolyte wetting, and superior power density.  \u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 133.2px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 42.475px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 42.475px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 42.475px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSCSMMHPC13 (C-SCS-MMHPC13)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 23.675px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 23.675px;\"\u003e\u003cem\u003eSpecific Surface Area5\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 23.675px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e500-600 m2\/g\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 36.7375px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 36.7375px;\"\u003e\u003cem\u003eTotal Pore Volume\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 36.7375px;\"\u003e\n\u003cp\u003e0.45-0.6 cm3\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 10px;\"\u003e\u003cem\u003ePore Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 10px;\"\u003e\n\u003cp\u003e20-100 nm, cover mesopore and macropore size range. \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20.3125px;\"\u003e\n\u003ctd style=\"width: 30.2158%; height: 20.3125px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.4245%; height: 20.3125px;\"\u003e5 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 meso\/macroporous carbon (HPC-13) 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\/S2352152X24040647\"\u003eD.
