{"product_id":"csbsseswcnt","title":"Self-Standing Single-Wall Carbon Nanotubes (SWCNT) Electrode (100mm * 100mm) for Supercapacitor and Battery, CSBSSESWCNT","description":"\u003cp\u003eA self-standing single-walled carbon nanotube (SWCNT) electrode is a sophisticated way to boost the performance of electrochemical energy storage devices. By eliminating the need for a metal current collector and polymer binders (like PVDF), you significantly increase the active material ratio and overall energy density. SWCNTs have a high aspect ratio and exceptional conductivity, they serve dual roles as both the active material and the current collector.\u003c\/p\u003e\n\u003cp\u003eIn Supercapacitor application field: (1) \u003cstrong\u003eEDLC Mechanism\u003c\/strong\u003e: SWCNTs provide a massive surface area for the formation of the Electric Double Layer (EDL). (2) \u003cstrong\u003eHigh Power Density\u003c\/strong\u003e: The lack of insulating binders allows for ultra-fast electron transport. (3) \u003cstrong\u003ePseudocapacitive Composites\u003c\/strong\u003e: SWCNT networks are often used as a \"scaffold\" for metal oxides (like MnO2) or conducting polymers (like PANI) to add high capacitance while maintaining high conductivity.\u003c\/p\u003e\n\u003cp\u003eFor\u003cstrong\u003e \u003c\/strong\u003eBatteries (Lithium\/Sodium Ion): (1) \u003cstrong\u003eAnode Support\u003c\/strong\u003e: Self-standing SWCNT mats can host high-capacity materials like Silicon (Si) or Tin (Sn). The flexible SWCNT network helps accommodate the large volume expansion these materials undergo during lithiation.
