{"product_id":"cafbccecmc","title":"Expanded Copper Mesh Chips (D=10-16 mm, T = 0.05-0.1 mm) as Anode-Free Battery Current Collector, 100 pcs\/bag, CAFBCCECMC","description":"\u003cp\u003eExpanded copper mesh chips (precision-cut pieces or discs of expanded copper mesh) represent an advanced 3D porous substrate architecture utilized in anode-free (zero-excess) battery configurations—including advanced aqueous zinc-ion, lithium, and sodium systems. Unlike flat, planar copper foil chips, expanded mesh features a diamond-shaped or rhombic open-mesh geometry created by simultaneously slitting and stretching solid copper sheet stock.\u003c\/p\u003e\n\u003cp\u003eThe key structural and electrochemical advantages of expanded copper mesh chips in anode-free cells are: (1) \u003cstrong\u003e3D Porous Architecture \u0026amp; Reduced Local Current Density\u003c\/strong\u003e: The open-mesh structure drastically increases the electrochemically active surface area compared to a smooth foil. By spreading the ionic flux over an expansive 3D network, the local current density (mA\/cm^2) is substantially lowered, preventing the high-current hotspots that typically drive dendritic metal electrodeposition during initial charging. (2) \u003cstrong\u003eEffective Accommodation of Volume Expansion\u003c\/strong\u003e: Anode-free cells rely on direct metal plating onto the substrate during charge and complete stripping during discharge. The spring-like, flexible architecture of expanded mesh accommodates the localized mechanical stress and volume breathing of the plated metal layer, reducing internal delamination and mechanical degradation. (3) \u003cstrong\u003eEnhanced Electrolyte Permeability and Wettability\u003c\/strong\u003e: The open apertures of the mesh allow unhindered electrolyte transport through the substrate thickness, ensuring that both sides of the mesh participate uniformly in charge transfer and metal nucleation.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100.036%; height: 100.8px;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.621%;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%;\"\u003e\n\u003cp\u003e\u003cspan\u003eCAFBCCECMC (C-AFBCC-ECMC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 33.621%; height: 10px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 10px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.99%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 90.8px;\"\u003e\n\u003ctd style=\"width: 33.621%; height: 90.8px;\"\u003e\u003cem\u003eSample Dimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 90.8px;\"\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\u003e\u003cspan\u003eThickness: 0.05 and 0.1 mm (other thickness in \u003cspan style=\"color: rgb(255, 42, 0);\"\u003e0.05-0.5 um \u003c\/span\u003eare also available upon request)\u003c\/span\u003e\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\u003cspan\u003e\u003ca href=\"https:\/\/pubs.acs.org\/aaemcq\/article-abstract\/8\/10\/6746\/3626576\/Physically-Coated-Gold-Film-on-Copper-Mesh?redirectedFrom=fulltext\"\u003eE.
