{"product_id":"cgpemtmc","title":"TMC {Trimethylene Carbonate, or 1,3-Dioxan-2-one, \u003e99.0%} as Monomer for Gel Polymer Electrolyte, 5-25 g\/bottle, CGPEMTMC","description":"\u003cp\u003eTrimethylene Carbonate (TMC)—systematically named 1,3-dioxan-2-one—is a six-membered cyclic carbonate ester. While traditional liquid electrolytes rely on five-membered cyclic carbonates like ethylene carbonate (EC) or propylene carbonate (PC), TMC is primarily used as a functional monomer for synthesizing poly(trimethylene carbonate) (PTMC) solid and gel polymer electrolytes, as well as a specialty co-solvent or precursor in high-safety lithium and post-lithium battery chemistries.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePolymer Matrix for All-Solid-State \u0026amp; Gel Electrolytes (PTMC)\u003c\/strong\u003e: Via Ring-Opening Polymerization (ROP), TMC easily forms poly(trimethylene carbonate) (PTMC), an amorphous, flexible aliphatic polycarbonate matrix. Unlike Poly(ethylene oxide) (PEO), which readily crystallizes at room temperature, PTMC exhibits a low glass transition temperature (Tg ~-15°C to -26°C), delivering high segmental mobility and enhanced ambient ionic conductivity without requiring high operating temperatures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Anodic Oxidation Stability (\u0026gt;4.5 V vs. Li\/Li+)\u003c\/strong\u003e: Carbonate ester linkages (-O-COO-) in the polymer backbone or liquid state possess lower HOMO energy levels compared to ether-based polymer matrices (like PEO). This wide electrochemical window enables PTMC-based solid-state electrolytes to operate alongside high-voltage cathodes like NMC811, LCO, and LNMO without severe oxidative degradation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIn Situ Polymerization for Seamless Interphase Contact\u003c\/strong\u003e: TMC monomer can be infiltrated into porous electrodes alongside lithium salts (LiTFSI, LiFSI) and polymerized in situ (thermally or catalytically) inside the cell. This eliminates high interfacial resistance commonly observed between solid polymer electrolytes and rigid electrode active materials.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuppression of Lithium Dendrite Growth\u003c\/strong\u003e: Cross-linked or copolymerized PTMC networks exhibit strong mechanical toughness and uniform Li+ flux distribution, suppressing lithium dendrite initiation and improving safety in lithium-metal batteries.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 336.25px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6875px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 47.6875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 47.6875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCGPEMTMC (C-GPE-M-TMC)\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\u003e2453-03-4\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 155.725px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 155.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 155.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CGPEMTMC_02_100x100.jpg?v=1785951163\" style=\"margin-bottom: 16px; float: none;\" width=\"78\" height=\"78\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.0576%;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.0%\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\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e102.09 g\/mol\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;\"\u003e5 g, 10 g, and 25 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 TMC monomer in a dry place. \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\/S1293255806001889\"\u003e\u003cspan\u003eM.
