{"product_id":"cbcccmafr","title":"Microporous Aluminum Foil Roll (T 12-20um * W 150-350mm) as Battery Cathode Current Collector, CBCCCMAFR","description":"\u003cp\u003eThe microporous aluminum current collector is a specialized cathode substrate used in high-performance lithium-ion batteries. Unlike standard \"solid\" aluminum foil, this version has a network of micro-scale holes (typically ranging from 30 um to 120 um in diameter) engineered into the metal. Microporous foil changes the internal physics of the cell:\u003c\/p\u003e\n\u003cp\u003e(1) \u003cstrong\u003eBidirectional Ion Transport\u003c\/strong\u003e: In a normal battery, lithium ions can only move through the separator. With porous collectors, ions can theoretically move through the collector itself. This effectively halves the transport distance for lithium ions, which can quadruple the battery's fast-charging (C-rate) capability.\u003c\/p\u003e\n\u003cp\u003e(2) \u003cstrong\u003eEnhanced Surface Adhesion\u003c\/strong\u003e: The \"holes\" and the rougher surface area created during processing act like mechanical anchors. This prevents the active cathode material from peeling off (delaminating) during the expansion and contraction of charging cycles.\u003c\/p\u003e\n\u003cp\u003e(3) \u003cstrong\u003eSuperior Electrolyte Infiltration\u003c\/strong\u003e: The pores allow the liquid electrolyte to soak into the electrode stack much faster and more uniformly during the \"wetting\" stage of manufacturing. This reduces production time and ensures there are no \"dry spots\" that lead to premature battery failure.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 121.638px;\"\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\u003eCBCCCMAFR (C-BCCC-MAFR)\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: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; 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: 45.8px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 45.8px;\"\u003e\u003cem\u003eMicroporous Aluminum Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 45.8px;\"\u003e\n\u003cp\u003e(1) T 12um * W 160mm * L 5m (pore size: 6-8 um)\u003c\/p\u003e\n\u003cp\u003e(2) T 15um * W 150mm * L 180m (pore size: 250 um)\u003c\/p\u003e\n\u003cp\u003e(3) T 15um * W 260mm * L 5m (pore size: 250 um)\u003c\/p\u003e\n\u003cp\u003e(4) T 15um * W 350mm * L 5m (pore size: 10 um)\u003c\/p\u003e\n\u003cp\u003e(5) T 16um * W 350mm * L 5m (pore size: 10 um)\u003c\/p\u003e\n\u003cp\u003e(6) T 18um * W 350mm * L 5m (pore size: 10 um)\u003c\/p\u003e\n\u003cp\u003e(7) T 20um * W 200mm * L 5m (pore size: 10 um)\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eOther customized sizes can be supplied 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","brand":"SZKJ","offers":[{"title":"T 12um * W 160mm * L 5m (pore size: 6-8 um)","offer_id":47058714460390,"sku":"CBCCCMAFRT12W160L5","price":119.0,"currency_code":"USD","in_stock":true},{"title":"T 15um * W 150mm * L 180m (pore size: 250 um)","offer_id":47058714493158,"sku":"CBCCCMAFRT15W150L180","price":269.0,"currency_code":"USD","in_stock":true},{"title":"T 15um * W 260mm * L 5m (pore size: 250 um)","offer_id":47766822715622,"sku":"CBCCCMAFRT15W260L5","price":89.0,"currency_code":"USD","in_stock":true},{"title":"T 15um * W 350mm * L 5m (pore size: 10 um)","offer_id":47766822748390,"sku":"CBCCCMAFRT15W350L5","price":219.0,"currency_code":"USD","in_stock":true},{"title":"T 16um * W 350mm * L 5m (pore size: 10 um)","offer_id":47766822781158,"sku":"CBCCCMAFRT16W350L5","price":179.0,"currency_code":"USD","in_stock":true},{"title":"T 18um * W 350mm * L 5m (pore size: 10 um)","offer_id":47766822813926,"sku":"CBCCCMAFRT18W350L5","price":179.0,"currency_code":"USD","in_stock":true},{"title":"T 20um * W 200mm * L 5m (pore size: 10 um)","offer_id":47766822846694,"sku":"CBCCCMAFRT20W200L5","price":189.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBCCCMAFR_main.jpg?v=1781408651","url":"https:\/\/echemsupplies.com\/products\/cbcccmafr","provider":"EChem Supplies","version":"1.0","type":"link"}
