{"product_id":"cafbcccfoamc","title":"Copper Foam Chips (D=10-16 mm, T=0.1 mm) as Anode-Free Battery Current Collector, 100 pcs\/bag, CAFBCCCFoamC","description":"\u003cp\u003eCopper foam chips (precision-cut discs, squares, or custom geometric pieces of 3D open-cell copper foam) represent a high-surface-area, sponge-like porous substrate architecture utilized in anode-free (zero-excess) battery configurations, including advanced aqueous zinc-ion and alkali-metal systems. Unlike flat, 2D copper foils or woven\/expanded meshes, copper foam features a continuous, highly interconnected 3D cellular framework that mimics a metallic sponge.\u003c\/p\u003e\n\u003cp\u003eThe key structural and electrochemical advantages of Cu foam chips in anode-free cells are: (1) \u003cstrong\u003eMassive 3D Surface Area \u0026amp; Low Local Current Density\u003c\/strong\u003e: The highly porous, open-cell architecture (typically achieving porosities of 90%+ and high specific surface areas) drastically dilutes the effective local current density (mA\/cm2). By distributing the incoming ionic flux across a vast internal network of interconnected ligaments, it eliminates the localized electric field hotspots that drive dendritic metal growth during initial charging. (2) \u003cstrong\u003eConfined Spatial Deposition (Internal Plating)\u003c\/strong\u003e: Rather than plating exclusively onto a flat top surface, metal ions migrate deep into the interior pores of the foam during initial charge. This spatial confinement accommodates substantial amounts of plated metal within the internal void volume without excessive outward swelling. (3) \u003cstrong\u003eExcellent In-Plane and Through-Plane Electrical Conductivity\u003c\/strong\u003e: Because the copper ligaments form an unbroken, continuous metallic network, the foam maintains ultra-low bulk electrical resistance across the entire electrode thickness, ensuring efficient electron transport to every internal deposition site.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100.036%; height: 102px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 29.5502%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70.1228%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCAFBCCCFoamC (C-AFBCC-CFoamC)\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: 29.5502%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70.1228%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.98%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 30.8px;\"\u003e\n\u003ctd style=\"width: 29.5502%; height: 30.8px;\"\u003e\u003cem\u003eSample Dimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 70.1228%; height: 30.8px;\"\u003e\n\u003cp\u003e\u003cspan\u003eDiameter: 10, 12, 14, and 16 mm\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eT-0.1 mm\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\u003ca href=\"https:\/\/www.pnas.org\/doi\/abs\/10.1073\/pnas.2315871121\"\u003e\u003cspan\u003eL.
