{"product_id":"clibahtdg","title":"High Tap Density Graphite Powder for Li-Ion Battery Anode, 100-500 g\/bottle, CLIBAHTDG","description":"\u003cp\u003eHigh-tap-density graphite is essential for maximizing the volumetric energy density of lithium-ion batteries. In industrial production, achieving high tap density (typically \u0026gt;1.0 g\/cm^3) involves specific material selection and particle engineering. The tap density of graphite powder is primarily a function of particle morphology and size distribution.\u003c\/p\u003e\n\u003cp\u003e(1) \u003cstrong\u003eSpheronization\u003c\/strong\u003e: Natural flake graphite is mechanically \"rounded\" into potato-like spheres. This reduces the specific surface area and allows particles to pack more tightly. Rounded natural graphite can reach tap densities near 1.0 g\/cm^3 compared to \u0026lt;0.5 g\/cm^3 for raw flakes.\u003c\/p\u003e\n\u003cp\u003e(2) \u003cstrong\u003eSecondary Particle Granulation\u003c\/strong\u003e: Small synthetic graphite grains are often clustered into larger, denser secondary particles. This \"cluster\" approach mimics the benefits of spherical shapes while maintaining the structural stability of synthetic graphite.\u003c\/p\u003e\n\u003cp\u003e(3) \u003cstrong\u003eParticle Size Distribution (PSD) Tuning\u003c\/strong\u003e: A bimodal or multimodal distribution (mixing larger and smaller particles) increases density. The smaller \"fine\" particles fill the interstitial voids between the larger \"coarse\" particles, reducing the overall volume occupied by the powder.\u003c\/p\u003e\n\u003cp\u003e(4) \u003cstrong\u003ePitch Coating\u003c\/strong\u003e: Coating spherical graphite with a thin layer of amorphous carbon (from coal tar or petroleum pitch) smoothens the particle surface, further increasing tap density and improving electrolyte compatibility.\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%; height: 443.2px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 29.2752%; height: 19.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70.509%; height: 19.6px;\"\u003eCLIBAHTDG (C-LIB-A-HTDG)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 142px;\"\u003e\n\u003ctd style=\"width: 29.2752%; height: 142px;\"\u003e\u003cem\u003eParticle Size Distribution\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70.509%; height: 142px;\"\u003e\n\u003cp\u003eD10 = 6.55 um, D50 = 14.63 um, D90 = 28.85 um\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CLIBAHTDG_PSD_160x160.png?v=1769930765\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 29.2752%; height: 19.6px;\"\u003eTap Density\u003c\/td\u003e\n\u003ctd style=\"width: 70.509%; height: 19.6px;\"\u003e1.10 g\/cm3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 29.2752%; height: 19.6px;\"\u003e\u003cem\u003eSpecific Area Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70.509%; height: 19.6px;\"\u003e1.65 m2\/g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 29.2752%; height: 19.6px;\"\u003e\u003cem\u003eWater Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70.509%; height: 19.6px;\"\u003e\u0026lt;0.07 wt%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 183.6px;\"\u003e\n\u003ctd style=\"width: 29.2752%; height: 183.6px;\"\u003e\u003cem\u003eFirst Discharge Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70.509%; height: 183.6px;\"\u003e\n\u003cp\u003e358.4 mAh\/g \u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CLIBAHTDG_Charging_Test_160x160.png?v=1769930763\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003eAnode recipe: Graphite: SP : SBR: CMC = 91: 5: 2.4: 1.6 \u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003eElectrolyte: 1M LiPF6 in EC\/EMC (1:1)\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003eDischarge: 0.1C to 0.001 V\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003eCharging: 0.1C to 2 V (cut off current 0.01C)\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 29.2752%; height: 19.6px;\"\u003e\u003cem\u003eFirst Columbic Efficiency\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70.509%; height: 19.6px;\"\u003e93.2% \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 29.2752%; height: 19.6px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70.509%; height: 19.6px;\"\u003e\n\u003cspan\u003e100 g, 200 g, and 500 g\/bottle (a \u003c\/span\u003e\u003cstrong\u003elarger quantity can be supplied upon request\u003c\/strong\u003e\u003cspan\u003e)\u003c\/span\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\u003cstrong\u003eNotes\u003c\/strong\u003e: (1) Please store the high tap density graphite powder in a dry area (glovebox is preferred); (2) The battery powder is highly recommended to be dried at 80-100°C in a vacuum oven for 6-12 h before use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S1872580521600513\"\u003eJ.
