{"product_id":"cscchmmhpc","title":"Micro\/Mesoporous Hierarchical-Porous-Carbon (PC-06L) as Conductive Host for S\/C Cathode, 5-20 g\/bottle, CSCCHMMHPC","description":"\u003cp\u003eA micro\/mesoporous hierarchical-porous-carbon (HPC) framework is widely regarded as one of the most effective conductive hosts for Lithium-Sulfur (Li-S) battery cathodes (S\/C composites).Lithium-sulfur batteries offer exceptionally high theoretical energy density (~1673 Wh\/kg), but practical implementation is historically hindered by major bottlenecks: the electrical insulation of sulfur, large volumetric expansion (~80%) during lithiation, and the notorious \"shuttle effect\" caused by the dissolution of intermediate lithium polysulfides (Li2Sx) in organic electrolytes. A hierarchical micro\/mesoporous carbon structure uniquely resolves these challenges by combining the distinct structural advantages of both pore regimes.\u003c\/p\u003e\n\u003cp\u003eIts main electrochemical advantages are: (1) \u003cstrong\u003eEnhanced Electrical Conductivity\u003c\/strong\u003e: The continuous graphitic carbon matrix provides a robust, highly conductive network that ensures rapid electron transfer to otherwise insulating sulfur and discharge products (Li2S2\/Li2S). (2) \u003cstrong\u003eSuperior Cycling Stability\u003c\/strong\u003e: Traditional mesoporous carbon hosts often suffer from gradual capacity decay because dissolved polysulfides escape into the electrolyte. The inclusion of a microporous network (or a micro-structured shell configuration) acts as a selective physical\/chemical barrier that stabilizes capacity over hundreds of cycles. (3) \u003cstrong\u003eHigh Rate Capability\u003c\/strong\u003e: The interconnected hierarchical channels (often extending down to macropores for multi-scale networks) ensure that both ionic and electronic transport kinetics remain unimpeded, delivering high capacity even at elevated current densities.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 163.2px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSCCHMMHPC (C-SCCH-MMHPC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 31.1875px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 31.1875px;\"\u003e\u003cem\u003eD50\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 31.1875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e8-10 um\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 19.6px;\"\u003e\u003cem\u003eTotal Pore Volume\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e1.65 cm3\/g\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePore Diameter\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e2-16 nm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 10px;\"\u003e\u003cem\u003ePore Distribution\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 10px;\"\u003e\n\u003cp\u003eMicropore+Mesopore\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eSurface Area (BET)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cp\u003e2000-2100 m2\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eMicropore Volume\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cp\u003e0.81 cm3\/g\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cp\u003e\u0026gt;99.99%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eSulfur Loading Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cp\u003e60-80 wt% (melting+diffusion)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 31.2125px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 31.2125px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 31.2125px;\"\u003e5 g, 10 g, and 20 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 PC-06L porous carbon 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\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S001346862200531X\"\u003e\u003cspan\u003eD.
