{"product_id":"cceacfswcnt","title":"Covalently Functionalized Single-Wall Carbon Nanotubes (SWCNTs, OCSiAl) as Conductive Electrode Additive, 1 g\/bottle, CCEACFSWCNT","description":"\u003cp\u003eIn electrochemical engineering, covalently functionalized single-wall carbon nanotubes (SWCNTs) are used as high-performance electrode additives to solve the primary weakness of pristine nanotubes: poor dispersion. While pristine SWCNTs tend to bundle together due to strong van der Waals forces, covalent functionalization attaches chemical groups directly to the sp2 carbon lattice, turning these bundles into a well-dispersed, 3D conductive network.\u003c\/p\u003e\n\u003cp\u003eThe addition of covalently functionalized SWCNTs to an electrode (typically at loadings as low as 0.1% to 1.0% wt) provides three major upgrades: (1) \u003cstrong\u003eSuperior Dispersion\u003c\/strong\u003e: Functional groups like -COOH (Carboxyl) or -NH2 (Amine) create electrostatic repulsion or hydrogen bonding with the solvent\/binder. This prevents the nanotubes from re-aggregating, ensuring they form a \"percolating\" network that reaches every active material particle. (2) \u003cstrong\u003eEnhanced Interfacial Adhesion\u003c\/strong\u003e: Covalent groups can act as chemical \"anchors\" between the nanotube and the polymer binder (like PVDF or CMC) or the active material (like Silicon or LFP). This creates a mechanically robust electrode that doesn't crack during the volume expansion of charging. (3) \u003cstrong\u003eSurface Wetting\u003c\/strong\u003e: Functionalization increases the hydrophilicity of the carbon. This allows the liquid electrolyte to penetrate deep into the nanopores of the electrode, reducing ion-transport resistance and boosting high-rate performance.\u003c\/p\u003e\n\u003ctable style=\"width: 115.193%; height: 279px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 40.7833%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 32.391%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCCEACFSWCNTH\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 26.5018%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCCEACFSWCNTC\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: 40.7833%; height: 35.6px;\"\u003e\u003cem\u003eFunctionalization Group\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 32.391%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eHydroxyl (-OH)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 26.5018%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCarboxyl (-COOH)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20.8px;\"\u003e\n\u003ctd style=\"width: 40.7833%; height: 20.8px;\"\u003e\u003cem\u003eOuter Diameter\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 32.391%; height: 20.8px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e1-2 nm\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 26.5018%; height: 20.8px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e1-2 nm\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 40.7833%; height: 19.6px;\"\u003e\u003cem\u003eLength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 32.391%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e1-50 um\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 26.5018%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e1-50 um\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 40.7833%; height: 19.6px;\"\u003e\u003cem\u003eSurface Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 32.391%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e350-500 m2\/g\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 26.5018%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e350-480 m2\/g\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 40.7833%; height: 10px;\"\u003eFunctionalization group content\u003c\/td\u003e\n\u003ctd style=\"width: 32.391%; height: 10px;\"\u003e\n\u003cp\u003e3.5-4.0 wt%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 26.5018%; height: 10px;\"\u003e\n\u003cp\u003e2.5-3.0 wt%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 40.7833%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 32.391%; height: 19.6px;\"\u003e1 g\/bottle\u003c\/td\u003e\n\u003ctd style=\"width: 26.5018%; height: 19.6px;\"\u003e1 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 covalently functionalized SWCNT 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\/S0013468620303273\"\u003eA.
