{"product_id":"cdebcceafr","title":"Etched Aluminum Foil Roll (T 15-20um * W 200mm) as Dry Electrode Battery Current Collector, CDEBCCEAFR","description":"\u003cp\u003eThe etched aluminum foil is an advanced current collector designed specifically to overcome the adhesion challenges of Dry Battery Electrode (DBE) manufacturing. In a dry process, the cathode material is applied as a self-supporting film without the help of liquid solvents or \"wet\" glues. Etched foil provides the mechanical \"teeth\" necessary to hold this dry film in place under high-pressure lamination.\u003c\/p\u003e\n\u003cp\u003eUnlike standard battery foil, which is \"smooth\" or \"plain,\" etched foil undergoes a chemical or electrochemical treatment that creates millions of microscopic pits or \"pores\" on the surface. (1) \u003cstrong\u003ePit Size\u003c\/strong\u003e: These pits are typically 1μm to 2μm in diameter. (2) \u003cstrong\u003eThe Anchor Effect\u003c\/strong\u003e: When the dry electrode film (composed of active materials and a PTFE binder) is hot-calendered onto the foil, the binder particles are squeezed into these pits. This creates a mechanical interlock, similar to how a climbing wall provides holds for a climber. (3)\u003cstrong\u003e Increased Surface Area\u003c\/strong\u003e: Etching can increase the effective surface area of the foil by 10 to 50 times without increasing its weight, providing more \"contact points\" for electrons to transfer.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 228.438px;\" 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\u003eCDEBCCEAFR (C-DEBCC-EAFR)\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\u003eDimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 45.8px;\"\u003e\n\u003cp\u003e(1) T 20um * W 200mm * L 10m\u003c\/p\u003e\n\u003cp\u003e(2) T 20um * W 200mm * L 45m (~0.5 kg)\u003c\/p\u003e\n\u003cp\u003e(3) T 20um * W 200mm * L 100m\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\u003eConductivity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e0.275 Ω g\/m2\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\u003eTensile Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e140 N\/mm2\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\u003eElongation Percentage\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e2.5%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eSurface Roughness\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cp\u003eRa =0.23-0.25 um\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eDyne Value\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cp\u003e\u0026gt;38\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":"KLD","offers":[{"title":"T 20um * W 200mm * L 10m","offer_id":47766852272358,"sku":"CDEBCCEAFRT20W200L10","price":149.0,"currency_code":"USD","in_stock":true},{"title":"T 20um * W 200mm * L 45m (~0.5 kg)","offer_id":47766852305126,"sku":"CDEBCCEAFRT20W200L45","price":249.0,"currency_code":"USD","in_stock":true},{"title":"T 20um * W 200mm * L 100m","offer_id":47766852239590,"sku":"CDEBCCEAFRT20W200L100","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CDEBCCEAFR_02.png?v=1766650359","url":"https:\/\/echemsupplies.com\/products\/cdebcceafr","provider":"EChem Supplies","version":"1.0","type":"link"}
