{"product_id":"cbacccf","title":"Copper Foam Sheet \u0026 Roll as Battery Anode Current Collector, CBACCCF","description":"\u003cp\u003eA copper foam anode current collector is an advanced three-dimensional (3D) porous material that moves beyond traditional 2D copper foils. It is essentially a \"metallic sponge\" with an interconnected network of copper ligaments and open pores. It has the following features of (a) \u003cstrong\u003eHigh Porosity\u003c\/strong\u003e: Typically ranges from 70% to 98%, meaning the material is mostly empty space. (b) \u003cstrong\u003e3D Interconnected Network\u003c\/strong\u003e: Unlike a mesh or perforated foil, the foam has a stochastic (randomized) honeycomb-like structure that provides electrical pathways in all directions. (c) \u003cstrong\u003eLarge Surface Area\u003c\/strong\u003e: Provides a massive amount of contact area for electrochemical reactions, significantly reducing local current density. \u003c\/p\u003e\n\u003cp\u003eCopper foam is specifically designed to solve the \"bottlenecks\" of high-capacity and high-safety batteries:\u003c\/p\u003e\n\u003cp\u003e(1) \u003cstrong\u003eDendrite Suppression\u003c\/strong\u003e: In lithium-metal batteries, lithium tends to grow in needle-like \"dendrites\" that cause fires. The 3D structure of the foam provides \"pockets\" for lithium to deposit uniformly, physically preventing dendrite growth.\u003c\/p\u003e\n\u003cp\u003e(2) \u003cstrong\u003eVolume Expansion Accommodation\u003c\/strong\u003e: High-capacity materials like Silicon expand massively during charging. The open pores of the foam provide internal room for this expansion, preventing the battery from swelling or the electrode material from cracking.\u003c\/p\u003e\n\u003cp\u003e(3) \u003cstrong\u003eUltra-Fast Charging (7C–10C)\u003c\/strong\u003e: Because the active material is embedded within the conductive foam rather than sitting on top of a flat sheet, electrons and ions have much shorter distances to travel. This can support full charges in under 10 minutes.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 217.438px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 40.2375px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 40.2375px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 40.2375px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBACCCF (C-BACC-CF)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 10px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 10px;\"\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: 167.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 167.2px;\"\u003e\u003cem\u003eDimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 167.2px;\"\u003e\n\u003cp\u003e(1) Sheet: T 0.1mm * W 100mm * L 100mm\u003c\/p\u003e\n\u003cp\u003e(2) Sheet: T 0.2mm * W 100mm * L 100mm\u003c\/p\u003e\n\u003cp\u003e(3) Sheet: T 0.3mm * W 100mm * L 100mm\u003c\/p\u003e\n\u003cp\u003e(4) Sheet: T 0.5mm * W 100mm * L 100mm\u003c\/p\u003e\n\u003cp\u003e(5) Sheet: T 0.8mm * W 100mm * L 100mm\u003c\/p\u003e\n\u003cp\u003e(6) Sheet: T 1.0mm * W 100mm * L 100mm\u003c\/p\u003e\n\u003cp\u003e(7) Roll: T 0.5mm * W 300mm * L 480mm\u003c\/p\u003e\n\u003cp\u003e(8) Roll: T 1.6mm * W 300mm * L 480mm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003eOther foam format\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cp\u003eIf customer need other foam format, we can provide it upon request.\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cimg height=\"85\" width=\"101\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/copper_foam_cylindrical_160x160.png?v=1766562302\" alt=\"\" style=\"float: none;\"\u003e  \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/copper_foam_cylindrical_02_160x160.png?v=1766562516\" style=\"margin-bottom: 16px; float: none;\" width=\"105\" height=\"108\"\u003e\u003cimg height=\"113\" width=\"122\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/copper_foam_cylindrical_03_160x160.png?v=1766562516\" style=\"margin-bottom: 16px; float: none;\"\u003e\n\u003c\/div\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\u003eReferences:\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/pubs.rsc.org\/en\/content\/articlelanding\/2018\/ta\/c8ta02810a\/unauth\"\u003eG.
