{"product_id":"csibasc","title":"Soft Carbon Powder for Na-Ion Battery Anode, 100-500 g\/bottle, CSIBASC","description":"\u003cp\u003eSoft carbon is a specific type of amorphous carbon used as an anode material, particularly in sodium-ion batteries (SIBs). Unlike hard carbon, which is \"non-graphitizable,\" soft carbon is \"graphitizable.\" This means that while it has a disordered structure, it will convert into ordered, crystalline graphite if heated to very high temperatures (e.g., above 2500°C). It is typically produced from precursors like petroleum coke or coal tar.\u003c\/p\u003e\n\u003cp\u003eSoft carbon normally has a unique \"turbostratic\" (disordered, layered) structure, like a messy and incomplete stack of paper. The layers are not perfectly aligned, creating more space than in graphite. When the battery is charged, sodium ions force their way between these disordered layers. This process expands the spacing between the carbon layers (e.g., from ~3.6 Å to ~4.2 Å). The \"electrochemically expandable\" structure enables the expansion is highly reversible. When the battery is discharged, the sodium ions exit, and the layers contract, allowing for a stable and long cycle life.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 552.8px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSIBASC (C-SIB-A-SC)\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: 33.6331%; height: 35.6px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003eParticle Size Distribution\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e D10 = 4.0 um,  \u003c\/span\u003e\u003cspan\u003eD50 = 8.5 um,  D90 = 16.0 um\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 19.6px;\"\u003e\u003cem\u003eTap Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e\u003cspan\u003e0.8 g\/cm3\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 19.6px;\"\u003e\u003cem\u003eSpecific Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e3.0 m2\/g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 250.8px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 250.8px;\"\u003e\u003cem\u003eFirst Discharging Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 250.8px;\"\u003e\n\u003cp\u003e~300 mAh\/g\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/C-SIB-A-SC-Charge-Dsicharge_160x160.jpg?v=1762796635\"\u003e\u003c\/div\u003e\n\u003cbr\u003e\n\u003cp\u003eElectrolyte: 1.0M NaPF6 in EC:DEC: EMC=1:1:1 vol% with 1%FEC\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 19.6px;\"\u003e\u003cem\u003eFirst Columbic Efficiency\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 19.6px;\"\u003e~84%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 172px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 172px;\"\u003e\u003cem\u003eCycling Stability \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 172px;\"\u003e\n\u003cp\u003e95% capacity retention after 500 cycles\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/C-SIB-A-SC-Cycling_Stability_160x160.jpg?v=1762796635\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6331%;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%;\"\u003e\n\u003cp\u003e100 g, 200 g, and 500 g\/bottle\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: (1) Please store the soft carbon powder in a dry area (glovebox is preferred); \u003c\/span\u003e\u003cspan\u003e(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\/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 rel=\"noopener\" href=\"https:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acs.chemmater.6b05474\" target=\"_blank\"\u003eZ.
