{"product_id":"cceacfmwcnt","title":"Covalently Functionalized Multi-Wall Carbon Nanotubes (MWCNTs, \u003e99%) as Conductive Electrode Additive, 10 g\/bottle, CCEACFMWCNT","description":"\u003cp\u003eCovalently functionalized Multi-Wall Carbon Nanotubes (MWCNTs) are a robust and cost-effective alternative to single-walled versions for improving the conductivity and mechanical stability of electrodes. While SWCNTs offer higher theoretical conductivity, MWCNTs are more resilient to the harsh chemical processing required for covalent functionalization. In electrochemical applications, these additives are used to create a persistent 3D conductive scaffold that remains intact throughout thousands of charge\/discharge cycles.\u003c\/p\u003e\n\u003cp\u003eAs an additive, covalently functionalized MWCNTs address three main bottlenecks: (1) \u003cstrong\u003ePercolation at Low Loading: \u003c\/strong\u003eBecause the functional groups prevent clumping, MWCNTs can achieve a \"percolation threshold\" (the point where a continuous conductive path is formed) at much lower concentrations—often 0.5-1.5 wt%. This leaves more room in the electrode for active material, increasing the overall energy density. (2) \u003cstrong\u003eInterfacial Resistance\u003c\/strong\u003e: The covalent groups provide a chemical \"bridge\" between the carbon nanotubes and the active material particles. This reduces the Contact Resistance, allowing electrons to flow more easily from the active site to the current collector, which is crucial for fast-charging applications. (3) \u003cstrong\u003eElectrolyte Accessibility\u003c\/strong\u003e: Untreated MWCNTs are hydrophobic. Functionalized MWCNTs (especially those with -OH or -COOH groups) improve the \"wettability\" of the electrode. This ensures that the electrolyte can penetrate the dense electrode structure, reducing the Ionic Resistance.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 121.969%; height: 200px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 27.6796%;
