{"product_id":"chtbspedspi","title":"Double-Side Coated Polyimide (PI) on PE Roll as High-Temperature Battery Separator, CHTBSPEDSPI","description":"\u003cp\u003eA polyimide (PI) coated polyethylene (PE) separator is a composite membrane that combines the safety \"shutdown\" feature of traditional polyethylene with the extreme heat resistance of polyimide It is typically created by coating a thin layer of thermally stable polyimide (or a polyimide\/ceramic blend) onto one or both sides of a standard microporous PE film. This dual-layer approach solves the biggest weakness of lithium-ion batteries: thermal shrinkage. The good heat management is reflected in two sides: (1) Thermal Shutdown (~135°C); (2) Structural Integrity (\u0026gt;200°C). Moreover, it also displays excellent features of superior electrolyte wetting, dendrite blocking, and oxidation resistance. \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: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCHTBSPEDSPI (C-HTBS-PEDSPI)\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\u003eMaterial\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003ePolyimide coated on PE substrate \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 49px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 49px;\"\u003eDimension\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 49px;\"\u003e\n\u003cp\u003e2 um PI + 12 um PE + 2 um PI\u003c\/p\u003e\n\u003cp\u003eW60 mm * L 50 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: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eArea Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e12.1 g\/m2\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePorosity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e42%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eSeparator Breakdown Temperature\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cp\u003e\u003cspan\u003e~ 203°C\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\u003ePuncture Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e608 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":"SZKJ","offers":[{"title":"Default Title","offer_id":47046413254886,"sku":"CHTBSPEDSPI","price":69.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/PI_coated_PE.jpg?v=1766133019","url":"https:\/\/echemsupplies.com\/products\/chtbspedspi","provider":"EChem Supplies","version":"1.0","type":"link"}
