{"product_id":"clsbcsc","title":"Sulfur-Carbon (S\/C, 75%) Composite Powder for Li-S Battery Cathode, 10 g\/bottle, CLSBCSC","description":"\u003cp\u003eS\/C composite powder is a promising cathode material for Li-S battery research.  The porous carbon matrix is essential for two critical reasons: (1) Electronic Conduction: The carbon provides the necessary pathway for electrons to reach the insulating sulfur particles and enable the electrochemical reactions. (2) Polysulfide Suppression: During cycling, sulfur dissolves into the electrolyte as large lithium polysulfide molecules (Li2Sx, where x=4-8). The porous structure of the carbon matrix physically traps these polysulfides, preventing them from dissolving and migrating to the anode—a process known as the shuttle effect, which causes rapid capacity fade.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 230.75px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 49.725px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 49.725px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 49.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCLSBCSC\u003c\/span\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e (C-LSB-C-SC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 35.6px;\"\u003e\u003cem\u003eChemical Composition\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eSulfur content is 75 wt%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 45.5375px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 45.5375px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003eParticle Size Distribution\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 45.5375px;\"\u003e\n\u003cp\u003e\u003cspan\u003eD10 = 5.1 um;  \u003c\/span\u003e\u003cspan\u003eD50 = 15.0 um;   D90 = 32.9 um\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 19.6px;\"\u003e\u003cem\u003eTap Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e0.39 g\/cm3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 10px;\"\u003e\u003cem\u003eFirst Discharging Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 10px;\"\u003e\n\u003cp\u003e~857 mAh\/g (0.1 C, 1.8-2.8 V)\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/C-LSB-C-SC-Charge_160x160.jpg?v=1763879069\" style=\"margin-bottom: 16px; float: none;\"\u003e  \u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003eConditions: (1) S\/C: Carbon Black: PVDF = 91% : 3%: 6%.
