{"product_id":"csbssemwcnt","title":"Self-Standing Multi-Wall Carbon Nanotubes (MWCNT) Electrode (100mm * 100mm) for Supercapacitor and Battery, CSBSSEMWCNT","description":"\u003cp\u003eA self-standing multi-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. MWCNTs 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: MWCNTs 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: MWCNT 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 MWCNT mats can host high-capacity materials like Silicon (Si) or Tin (Sn). The flexible MWCNT network helps accommodate the large volume expansion these materials undergo during lithiation. (2) \u003cstrong\u003eLithium Metal Anodes\u003c\/strong\u003e: They can act as a 3D \"host\" to regulate lithium plating, preventing the growth of dangerous dendrites.\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%; height: 217.275px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 41.175px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 41.175px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 41.175px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSBSSEMWCNT (C-SB-SSE-MWCNT)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.9px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 22.9px;\"\u003e\u003cem\u003eEffective Electrode Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 22.9px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e100 mm * 100 mm\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 19.6px;\"\u003e\u003cem\u003eElectrode Thickness \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 19.6px;\"\u003e4-8 um\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 19.6px;\"\u003e\u003cem\u003eElectrical Conductivity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 19.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e3*10^-5 to 5*10^-5 S\/m\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 39.2px;\"\u003e\u003cem\u003eTensile Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 39.2px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e60-120 MPa\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 39.2px;\"\u003e\u003cem\u003eSpecific Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 39.2px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e450-650 mAh\/g\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 35.6px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 35.6px;\"\u003e\n\u003cp\u003e1 pcs\/pack\u003c\/p\u003e\n\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 self-standing MWCNT electrode sheet in a dry place and do vacuum drying (90-100 °C) for 12-24 h. \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:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acsaem.8b00583\"\u003eA.
