In advanced energy storage research, Photoinitiator 907 is utilized for the rapid UV-curing of Gel Polymer Electrolytes (GPEs) and solid-state polymer electrolyte systems, providing efficient free-radical generation to polymerize acrylate and methacrylate network precursors directly within 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-Gelation in Sealed Cells\u003c\/strong\u003e: Enables the fast conversion of low-viscosity liquid electrolyte\/monomer precursors (such as PEGDA, TPGDA, HDDA, or HDDMA blended with carbonate solvents and lithium\/sodium salts) into dimensionally stable, crosslinked gel networks within seconds to minutes under UV exposure. (2) \u003cstrong\u003eElimination of Thermal Stress \u0026amp; Side Reactions\u003c\/strong\u003e: Replaces traditional thermal radical initiators (such as AIBN or BPO) with a clean, room-temperature light-triggered mechanism, avoiding thermal expansion mismatches between cell components and preventing premature thermal decomposition of volatile components. (3) \u003cstrong\u003eUniform 3D Network Formation\u003c\/strong\u003e: Because Photoinitiator 907 distributes evenly throughout the liquid electrolyte phase without micro-scale phase separation, free radicals are generated homogeneously across separator pores and electrode microstructures, establishing 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: 427.562px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSSGPEPI907 (C-SSGPE-PI907)\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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e71868-10-5\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 169.725px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 169.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 169.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e15\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e21\u003c\/sub\u003e\u003cspan\u003eNO\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eS\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\/CSSGPEPI907_structure_160x160.jpg?v=1793509721\" 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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eWhite Powder\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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\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: 36.6px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 36.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 36.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e279.40 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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eMelt Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e70-75 °C\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 17.2px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 17.2px;\"\u003e\u003cem\u003eAbsorption Wavelength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 17.2px;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e230 nm and 303 nm (in ethanol solution)\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: 28.0702%; height: 26.0375px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; 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\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the photoinitiator 907 powder in a dry place and dark.\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\/S2352152X25049862\"\u003e\u003cspan\u003eT.
