{"product_id":"cceavgcfhp","title":"Vapor Grown Carbon Fiber (VGCF-H) Powder as Conductive Electrode Additive, 10 g\/bottle, CCEAVGCFHP","description":"\u003cp\u003eVapor Grown Carbon Fiber (VGCF-H) is a highly graphitized, one-dimensional (1D) conductive additive used in a variety of electrochemical applications. It is synthesized through chemical vapor deposition (CVD) and is prized for its ability to form network-like \"bridges\" that connect active material particles over long distances. The key features of VGCF-H are: (1) \u003cstrong\u003eLong-Distance Conductive Paths\u003c\/strong\u003e: While carbon black (Super P) provides \"point-to-point\" contact at short ranges, the fibrous structure of VGCF (up to 20 µm in length) creates long-range electrical highways. This is especially critical in thick electrodes where electrons must travel further to reach the current collector. (2) \u003cstrong\u003eMechanical Reinforcement\u003c\/strong\u003e: It acts as a structural anchor. During the expansion and contraction of active materials (e.g., in Silicon-rich anodes), VGCF fibers maintain electrical contact where brittle spherical additives might fail. (3) \u003cstrong\u003eElectrolyte Absorption \u0026amp; Wicking\u003c\/strong\u003e: The hollow microstructure of VGCF allows it to absorb and hold liquid electrolyte. This facilitates faster ion transport and improves performance during high-rate (C-rate) discharge and low-temperature operation. \u003c\/p\u003e\n\u003cp\u003e(1) In battery applications, VGCF-H is normally used in both cathodes (NMC, LFP) and anodes to improve current distribution. It is often paired with Super P in a hybrid conductive network for optimal performance.\u003c\/p\u003e\n\u003cp\u003e(2) In electrolyzer and fuel cell application, VGCF-H is incorporated into the Microporous Layer (MPL) or catalyst layers to manage water and gas transport. It creates larger pore volumes, which helps reduce water flooding at the cathode.\u003c\/p\u003e\n\u003cp\u003e(3) In supercapacitor system, VGCF-H is added to aerogel or porous carbon electrodes to reduce internal resistance and increase power density through synergistic effects with pseudocapacitive materials like polypyrrole.\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\u003eCCEAVGCFHP (C-CEA-VGCFHP)\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\u003eAverage Diameter of VGCF-H\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 31.1875px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e~150 nm\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\u003eAverage Length of VGCF-H\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e~8 um\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\u003eResistivity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e0.1 mΩ cm\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\u003eSurface Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 10px;\"\u003e\n\u003cp\u003e13 m2\/g (BET)\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;\"\u003e10 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 VGCF-H 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\/S0378775310018926\"\u003eS.
