{"product_id":"cbcccapcfr","title":"Aluminum\/PET Composite Foil Roll (Al\/PET, T 6.5-8.0um * W 180-300mm) as Battery Cathode Current Collector, CBCCCAPCFR","description":"\u003cp\u003eThe Al\/PET\/Al composite foil is a next-generation \"sandwich-structured\" material designed to replace solid aluminum foils in the positive electrodes (cathodes) of lithium-ion batteries. It consists of a central PET (polyethylene terephthalate) plastic core flanked by ultra-thin layers of aluminum on both sides. This technology addresses the two biggest challenges in modern battery design: weight reduction and fire safety. Its main advantages are (1) improved safety, (2) increased energy density, (3) Elimination of \"aluminum burrs\", (4) decreased cost. \u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 243.037px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 40.2375px;\"\u003e\n\u003ctd style=\"width: 33.0882%; height: 40.2375px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7017%; height: 40.2375px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBCCCAPCFR (C-BCCC-APCFR)\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: 33.0882%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7017%; 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: 167.2px;\"\u003e\n\u003ctd style=\"width: 33.0882%; height: 167.2px;\"\u003e\u003cem\u003eComposite Al Foil Sizes\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7017%; height: 167.2px;\"\u003e\n\u003cp\u003e(1) T (1+4.5+1)um * W 200mm * L 5m\u003c\/p\u003e\n\u003cp\u003e(2) T (1+4.5+1)um * W 300mm * L 5m\u003c\/p\u003e\n\u003cp\u003e(3) T (1+6+1)um * W 180mm * L 5m\u003c\/p\u003e\n\u003cp\u003e(4) T (1+6+1)um * W 180mm * L 20m\u003c\/p\u003e\n\u003cp\u003e(5) T (1+6+1)um * W 280mm * L 50 m\u003c\/p\u003e\n\u003cp\u003eFor example, the sandwich structures for T(1+4.5+1) um and T(1+6+1) um are shown below:\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/composite_Al_foil_structure_02_160x160.png?v=1766630334\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/composite_Al_foil_structure_160x160.png?v=1766629825\"\u003e\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","brand":"CXJS","offers":[{"title":"T (1+4.5+1)um * W 200mm * L 5m","offer_id":47058396315878,"sku":"CBCCCAPCFRT65W200L5","price":139.0,"currency_code":"USD","in_stock":true},{"title":"T (1+4.5+1)um * W 300mm * L 5m","offer_id":47058396348646,"sku":"CBCCCAPCFRT65W300L5","price":179.0,"currency_code":"USD","in_stock":true},{"title":"T (1+6+1)um * W 180mm * L 5m","offer_id":47766838706406,"sku":"CBCCCAPCFRT8W180L5","price":99.0,"currency_code":"USD","in_stock":true},{"title":"T (1+6+1)um * W 180mm * L 20m","offer_id":47884839747814,"sku":"CBCCCAPCFRT8W180L20","price":179.0,"currency_code":"USD","in_stock":true},{"title":"T (1+6+1)um * W 280mm * L 50 m","offer_id":47766838739174,"sku":"CBCCCAPCFRT8W280L50","price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBCCCAPAFR.png?v=1766630743","url":"https:\/\/echemsupplies.com\/products\/cbcccapcfr","provider":"EChem Supplies","version":"1.0","type":"link"}
