{"product_id":"casbsc","title":"NKK Cellulose Roll (TF4030, TF4425, TF4530) as Aqueous Supercapacitor and Battery Separator, CASBSC","description":"\u003cp\u003eCellulose separators are highly valued as a sustainable, high-performance alternative to traditional synthetic polymers like polypropylene, which is ascribed to its superior electrolyte absorption and low internal resistance. (1) Exceptional Wettability \u0026amp; \"Sponge\" Effect: Unlike standard plastic separators (which are naturally water-repellent), cellulose is packed with hydroxyl (-OH) groups that make the separator act like a high-tech sponge, instantly soaking up electrolyte. This ensures that the interface between the electrode and the separator is always saturated, allowing for the fastest possible ion transport. (2) Low ESR (Equivalent Series Resistance): Cellulose separators often have a porosity of 60% to 75% or higher. The open structure of cellulose minimizes this resistance, leading to a much lower ESR compared to dense polymer films. (3) Thermal \u0026amp; Dimensional Stability: the melting point of cellulose remains stable up to 250°C or higher.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 375.6px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCASBSC (C-ASBS-C)\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: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eMaterial\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003eCellulose\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 162px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 162px;\"\u003eRoll Type and Dimension\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 162px;\"\u003e\n\u003cp\u003e(1) TF4030: W60 mm * L60 m * T30 um (1 roll\/pack)\u003c\/p\u003e\n\u003cp\u003e(2) TF4425: W60 mm * L50 m * T25 um (1 roll\/pack)\u003c\/p\u003e\n\u003cp\u003e(3) TF4530: W60 mm * L60 m * T30 um (1 roll\/pack)\u003c\/p\u003e\n\u003cp\u003e(4) TF4530: W60 mm * L500 m * T30 um (1 roll\/pack)\u003c\/p\u003e\n\u003cp\u003e(Roll with other width and length can be provided upon request)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 142.4px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 142.4px;\"\u003e\u003cem\u003eParameters\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 142.4px;\"\u003e\n\u003cp\u003e                    Thickness        Density          Porosity\u003c\/p\u003e\n\u003cp\u003eTF4030:          30 um           0.40 g\/cm3       73%\u003c\/p\u003e\n\u003cp\u003eTF4425:          25 um           0.44 g\/cm3       71%\u003c\/p\u003e\n\u003cp\u003eTF4530:          30 um           0.45 g\/cm3       70%\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\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S1572665722009298\"\u003eB.
