{"product_id":"cbsapvdf","title":"Alumina and PVDF Coated PE Roll as Battery Separator, CBSAPVDF","description":"\u003cp\u003e\u003cbr\u003eThe alumina and PVDF-coated PE separator is an advanced multi-layer membrane designed for high-energy density and high-safety lithium-ion batteries. (1) The PE base provides the essential thermal shutdown feature. If the battery overheats, the PE melts at ~135°C to block ion flow. (2) The alumina ceramic prevents thermal shrinkage. While raw PE would shrivel after melting, the alumina particles stay solid (up to 2000°C), keeping the electrodes physically separated. (3) PVDF has excellent affinity for liquid electrolytes. It acts like a \"glue\" that not only holds the ceramic to the PE but also helps the electrolyte soak into the separator, lowering internal resistance.\u003c\/p\u003e\n\u003cp\u003eThe composite separator combines above features and delivers the following advantages: (1) Superior thermal safety; (2) Enhanced puncture resistance; (3) Stronger adhesion; (4) High voltage stability.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 262.6px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 27.1583%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.482%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBSAPVDF (C-BS-APVDF)\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: 27.1583%; height: 35.6px;\"\u003e\u003cem\u003eMaterial\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.482%; height: 35.6px;\"\u003e\n\u003cp\u003eAlumina and PVDF coated on PE \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 49px;\"\u003e\n\u003ctd style=\"width: 27.1583%; height: 49px;\"\u003eDimension\u003c\/td\u003e\n\u003ctd style=\"width: 72.482%; height: 49px;\"\u003e\n\u003cp\u003e(1) Double Coating at Same Side: 12 um PE + 2 um Al2O3 +2 um PVDF (W60 mm*L10 m)\u003c\/p\u003e\n\u003cp\u003e(2) Single Coating at Both Sides: 2 um Al2O3 + 12 um PE + 2 um PVDF (W60 mm*L10 m)\u003c\/p\u003e\n\u003cp\u003e(Roll with other width and length can be provided upon request)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 27.1583%; height: 35.6px;\"\u003e\u003cem\u003eArea Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.482%; height: 35.6px;\"\u003e\n\u003cp\u003e~12.1 g\/m2\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 27.1583%; height: 35.6px;\"\u003e\u003cem\u003ePorosity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.482%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e~40%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 27.1583%;\"\u003e\u003cem\u003eGas Flow Through Rate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.482%;\"\u003e\n\u003cp\u003e\u003cspan\u003e217.8 s\/100 mL\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: 27.1583%; height: 35.6px;\"\u003e\u003cem\u003ePuncture Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.482%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e526 g\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":"KGKY","offers":[{"title":"Double Coating at Same Side: 12 um PE + 2 um Al2O3 +2 um PVDF","offer_id":47046867255526,"sku":"CBSDCSSPE16A2P2","price":79.0,"currency_code":"USD","in_stock":true},{"title":"Single Coating at Both Sides: 2 um Al2O3 + 12 um PE + 2 um PVDF","offer_id":47046867288294,"sku":"CBSSCBSA2PE16P2","price":79.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBSAPVDF.png?v=1766165609","url":"https:\/\/echemsupplies.com\/products\/cbsapvdf","provider":"EChem Supplies","version":"1.0","type":"link"}
