{"product_id":"clibdehlg","title":"Graphite Dry Electrode (Disc, Sheet) with High Loading (18.9-27.4 mg\/cm2) for Li-Ion Battery, CLIBDEHLG","description":"\u003cp\u003eCreating a high-loading graphite dry electrode for lithium-ion batteries (LIB) is a critical step in reducing manufacturing costs and increasing energy density. By eliminating the solvent-drying step, you can produce electrodes that are much thicker than traditional wet-coated ones without the risk of cracking or \"binder migration\" (where the binder floats to the surface, leaving the bottom of the electrode brittle).\u003c\/p\u003e\n\u003cp\u003eGraphite particles are typically flaky or spherical (mesocarbon microbeads). Unlike polyanion cathodes, graphite is relatively soft but has a slippery surface. (1) \u003cstrong\u003eBinder Choice\u003c\/strong\u003e: PTFE (Polytetrafluoroethylene) is the standard for dry electrodes. For high loading, a concentration of 3–6% PTFE is typical. (2) \u003cstrong\u003eShear Force\u003c\/strong\u003e: High-shear mixing (using a jet mill or a high-speed cyclomix) is required to \"tease out\" the fibrils from the PTFE granules. These fibrils act as a microscopic web that traps the graphite particles.\u003c\/p\u003e\n\u003cp\u003eIn traditional wet coating, thick electrodes often peel off the copper foil during drying. Dry processing solves this, but introduces new variables: (1) \u003cstrong\u003eElectrode Thickness\u003c\/strong\u003e: Dry processing easily achieves thicknesses of 200 μm to 500 μm. However, at these levels, ion transport becomes the bottleneck. (2) \u003cstrong\u003eVertical Pore Engineering\u003c\/strong\u003e: High-loading graphite can become too dense during calendering, leading to high tortuosity (a \"winding path\" for ions). You must balance the calendering pressure to maintain a porosity of 25–35% to allow the electrolyte to penetrate the full depth of the electrode. (3) \u003cstrong\u003eConductive Additives\u003c\/strong\u003e: While graphite is conductive, adding 0.5–1% Carbon Nanotubes (CNTs) is highly recommended for high loadings. CNTs bridge the gap between graphite flakes more effectively than Carbon Black, ensuring a stable electronic path throughout the thick sheet.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eGraphite Dry Electrode can be used as sodium-ion battery cathode. The round disc shape with single-side coating is suitable for coin cell testing, while the rectangle sheet shape with single- or double-side coating is designed for single-layer or multiple-layer pouch cell testing.\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 101.462%; height: 396px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 28.2001%; height: 19.6px;\"\u003e\u003cem\u003ePart Number \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5894%; height: 19.6px;\"\u003eCLIBDEHLG (C-LIB-DEHL-G)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 31.6px;\"\u003e\n\u003ctd style=\"width: 28.2001%; height: 31.6px;\"\u003e\u003cem\u003eCurrent collector\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5894%; height: 31.6px;\"\u003e9 um copper foil with carbon coating (1 um on each side)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 28.2001%; height: 19.6px;\"\u003e\u003cem\u003eDry Coating Material\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5894%; height: 19.6px;\"\u003eGraphite powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 28.2001%; height: 19.6px;\"\u003e\u003cem\u003eActive Portion\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5894%; height: 19.6px;\"\u003e96.0%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 197.6px;\"\u003e\n\u003ctd style=\"width: 28.2001%; height: 197.6px;\"\u003e\u003cem\u003eElectrode Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5894%; height: 197.6px;\"\u003e\n\u003cp\u003e(1) Round disc shape: D = 10 -15 mm\u003c\/p\u003e\n\u003cp\u003e(2) Rectangle sheet shape:\u003c\/p\u003e\n\u003cp\u003e     (a) 18.9 mg\/cm2, single-side, 1.31 g\/cm3, L120 mm*W90 mm\u003c\/p\u003e\n\u003cp\u003e     (b) 27.4 mg\/cm2, single-side, 1.31 g\/cm3, L120 mm*W90 mm\u003c\/p\u003e\n\u003cp\u003eThe double side coating dry electrodes can be supplied upon request. \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 71.2px;\"\u003e\n\u003ctd style=\"width: 28.2001%; height: 71.2px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5894%; height: 71.2px;\"\u003e\n\u003cp\u003eRound disk D=10-15 mm (50 pcs\/pack)\u003c\/p\u003e\n\u003cp\u003eRectangle sheet with SS coating (5 pcs\/pack)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 28.2001%; height: 10px;\"\u003e\u003cem\u003eFirst Discharging Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5894%; height: 10px;\"\u003e\n\u003cp\u003e~350 mAh\/g (0.1 C)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.8px;\"\u003e\n\u003ctd style=\"width: 28.2001%; height: 26.8px;\"\u003e\u003cem\u003eFirst Columbic Efficiency\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5894%; height: 26.8px;\"\u003e95.2 %\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: (1) Please store the graphite electrodes in a dry area (glovebox is preferred); \u003c\/span\u003e\u003cspan\u003e(2) The battery electrodes are highly recommended to be dried at 80-100°C in a vacuum oven for 6-12 h before use. \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\u003ca href=\"https:\/\/www.cell.com\/joule\/fulltext\/S2542-4351(24)00055-2?uuid=uuid%3A7c71cd45-b89d-49df-b0ab-d9dd26e7e8ac\"\u003e\u003cspan\u003eZ.
