{"product_id":"cbssepec","title":"PEC {(Poly(ethylene carbonate)} Granulate as Solid-State Battery Electrolyte, 20-100 g\/bottle, CBSSEPEC","description":"\u003cp\u003ePoly(ethylene carbonate) (PEC) has emerged as a highly promising polymer matrix for solid-state batteries, particularly as an alternative to the traditional Poly(ethylene oxide) (PEO). While PEO-based systems suffer from poor ionic conductivity at room temperature (requiring heating to 60°C to cross into its amorphous, conductive phase) and a narrow electrochemical stability window (~3.9 V), PEC addresses several of these fundamental limitations.\u003c\/p\u003e\n\u003cp\u003ePEC's backbone contains alternating ethylene and carbonate groups. This chemical structure alters how it interacts with metal ions \u003cspan data-index-in-node=\"132\" data-math=\"\\text{Li}^+\" class=\"math-inline\"\u003eLi+\u003c\/span\u003e, \u003cspan data-index-in-node=\"145\" data-math=\"\\text{Na}^+\" class=\"math-inline\"\u003eNa}+\u003c\/span\u003e) compared to polyethers: (1) \u003cstrong\u003eAmorphous Nature\u003c\/strong\u003e: Unlike highly crystalline PEO, PEC is inherently amorphous at room temperature. This eliminates the need to operate the battery at elevated temperatures to facilitate ion transport. (2) \u003cstrong\u003eHigh Dielectric Constant\u003c\/strong\u003e: The polar carbonate groups (C=O) give PEC a high dielectric constant. This enables excellent dissociation of lithium salts (like LiTFSI) or sodium salts (like NaTFSI), generating a higher concentration of free mobile charge carriers. (3) \u003cstrong\u003eHigh Oxidation Stability\u003c\/strong\u003e: The electron-withdrawing nature of the carbonyl group lowers the highest occupied molecular orbital (HOMO) energy level. This gives PEC an expanded electrochemical stability window, typically stable up to 4.5 V to 4.8 V vs. Li\/Li+, making it compatible with high-voltage cathodes like NCM811 or ultra-high nickel variants.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 378.438px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBSSEPEC (C-BSSE-PEC)\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: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e25718-55-2\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 117px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 117px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 117px;\"\u003e\n\u003cp\u003e(C3H4O3)n\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBSSEPEC_02_100x100.jpg?v=1783007921\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eWhite Granulate\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: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eDensity \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e1.42 g\/cm3\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: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eRefractive Index\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e1.47\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 39.2px;\"\u003e\u003cem\u003eDecomposition Temperature\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 39.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003e220℃\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 18.2px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 18.2px;\"\u003e\u003cem\u003eGlass Transition Temperature\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 18.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003e0-10\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.0375px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 26.0375px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 26.0375px;\"\u003e50 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the PEC Granulate in a dry place (glovebox is preferred). \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S1388248116300467\"\u003e\u003cspan\u003eK.
