{"product_id":"csbssge","title":"Self-Standing Graphene Electrode (L100mm * W100mm * T25um) for Supercapacitor and Battery, CSBSSGE","description":"\u003cp\u003eA self-standing graphene film (also known as \"graphene paper\") is a macro-scale, binder-free architecture that acts as both the active storage material and the current collector. By eliminating heavy metal foils (Cu\/Al) and non-conductive polymer binders, these films drastically improve the gravimetric energy density of electrochemical devices.\u003c\/p\u003e\n\u003cp\u003eUnlike traditional slurry-cast electrodes, self-standing films offer structural and electrical advantages: (1) \u003cstrong\u003eHigh Conductivity\u003c\/strong\u003e: The continuous overlapping of graphene sheets provides a low-resistance path for electrons (\u0026gt;2.0*10^5 S\/cm) in high-quality films). (2) \u003cstrong\u003eFlexibility\u003c\/strong\u003e: They can be bent, folded, or rolled without cracking, making them essential for wearable electronics and foldable batteries. (3) \u003cstrong\u003eRapid Ion Diffusion\u003c\/strong\u003e: When engineered with hierarchical pores, they provide \"ion highways,\" significantly reducing the diffusion distance compared to thick, dense graphite. (4) \u003cstrong\u003eSynergistic Composites\u003c\/strong\u003e: They act as a 3D conductive \"scaffold\" for host materials like Silicon (Si) or Metal Oxides (MnO2), accommodating their volume expansion and preventing mechanical failure.\u003c\/p\u003e\n\u003cp\u003eFor supercapacitor application, self-standing graphene films are the \"gold standard\" for high-power capacitors. (1) \u003cstrong\u003ePerformance\u003c\/strong\u003e: They can reach volumetric capacitances of 130 F\/cm3 and maintain stability over 20,000 cycles. (2) \u003cstrong\u003eMechanism\u003c\/strong\u003e: They utilize Electric Double-Layer Capacitance (EDLC). To increase energy, these films are often doped with Nitrogen (N) or Boron (B) to introduce pseudocapacitive redox sites.\u003c\/p\u003e\n\u003cp\u003eIn battery application field, (1) \u003cstrong\u003eAnode\u003c\/strong\u003e: Pure graphene films can provide capacities of 450–700 mAh\/g. (2) \u003cstrong\u003eFolded Architectures\u003c\/strong\u003e: Recent research shows that folding these films (like origami) increases areal loading without sacrificing the fast electron transport paths, allowing for capacities that exceed commercial graphite (\u0026gt;4.0 mAh\/cm^2).\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100.036%; height: 205.275px;\"\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\u003eCSBSSGE (C-SB-SSGE)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 30.3848%;\"\u003e\u003cem\u003eFabrication Processes\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%;\"\u003e\n\u003cp\u003e\u003cspan\u003eGraphene oxide was adopted as raw material, which was went through steps of film coating, pre-reduction, graphitization, and press.  \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;\"\u003e25 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;\"\u003e2*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;\"\u003e~35 MPa\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 23.6px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 23.6px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 23.6px;\"\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 graphene 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.rsc.org\/en\/content\/articlehtml\/2017\/se\/c6se00047a\"\u003eG.
