By absorbing near-UV or violet light, TPO-L rapidly generates free radicals to initiate the polymerization of acrylate, methacrylate, and thiol-ene network precursors directly within porous separator membranes and electrode assemblies.\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003eIts functional roles in GPEs synthesis are: (1) \u003cstrong\u003eRapid In Situ UV-Curing in Sealed Cells\u003c\/strong\u003e: TPO-L enables the rapid conversion of low-viscosity liquid electrolyte\/monomer precursors (such as PEGDA, TPGDA, HDDA, or PEGMA blended with carbonate solvents and LiPF6\/LiTFSI) into solid or dimensionally stable gel networks upon exposure to long-wavelength UV light (compatible with transparent pouch cell windows or quartz-faced coin cells). (2) \u003cstrong\u003eElimination of Thermal Stress During Curing\u003c\/strong\u003e: Unlike thermal initiators (such as AIBN or BPO) that require prolonged heating (55°C-70°C), UV initiation via TPO-L occurs rapidly at ambient temperatures, preventing thermal expansion mismatch between cell components and avoiding premature thermal degradation of volatile solvent components. (3) \u003cstrong\u003eUniform Network Crosslinking\u003c\/strong\u003e: Because TPO-L dissolves completely into the liquid electrolyte mixture without phase separation, free radicals are generated homogeneously throughout the separator pores and electrode microstructures, resulting in a uniform 3D polymer mesh with high ionic conductivity (\u0026gt;10^{-3} S\/cm).\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ctable style=\"width: 100%; height: 365.762px;\" 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\u003eCSSGPEPITPOL (C-SSGPE-PI-TPOL)\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\u003e84434-11-7\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 151.725px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 151.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 151.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e1\u003c\/sub\u003e\u003csub\u003e8\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003csub\u003e1\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eP\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CSSGPEPITPOL_structure_160x160.jpg?v=1793432839\" 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\u003eLight yellow to orange clear liquid\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\u003e316.33 g\/mol\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\u003e~1.13 – 1.14 g\/cm³\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 10px;\"\u003e\u003cem\u003eFlash Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 10px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e144 °C to 184 °C\u003cbr\u003e\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, 100 g, and 200 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 TPOL liquid 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:\/\/onlinelibrary.wiley.com\/doi\/full\/10.1002\/eem2.70190\"\u003e\u003cspan\u003eE.
