In advanced energy storage research, BAPO is utilized as a premier UV-curing photoinitiator for Gel Polymer Electrolytes (GPEs) and solid-state polymer electrolytes, offering deep-section curing capabilities, high absorption efficiency in the long-wavelength UV\/violet spectrum, and rapid polymerization kinetics for high-energy lithium and sodium metal batteries.\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003eIts functional roles in GPEs synthesis are: (1) \u003cstrong\u003eDeep-Curing of Thick Separators \u0026amp; Electrodes\u003c\/strong\u003e: Because BAPO absorbs at longer, highly penetrating wavelengths, it successfully initiates radical polymerization deep within thick, porous separator matrices (such as glass fiber or high-loading composite electrodes) where shorter UV wavelengths would be blocked or scattered. (2) \u003cstrong\u003eRapid In Situ UV-Gelation in Sealed Cells\u003c\/strong\u003e: Enables the fast conversion of liquid precursor solutions (comprising structural crosslinkers like TPGDA, HDDA, or PEGDA dissolved in carbonate electrolytes and battery salts) into robust, dimensionally stable gel networks within minutes under UV exposure. (3) \u003cstrong\u003eElimination of Thermal Stress \u0026amp; Side Reactions\u003c\/strong\u003e: Replaces thermal initiators (like AIBN or BPO) with a clean, room-temperature light-triggered mechanism, avoiding thermal expansion mismatches and preventing premature side reactions during cell assembly.\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\u003eCSSGPEPIBAPO (C-SSGPE-PI-BAPO)\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\u003e162881-26-7\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\u003e[(CH\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003e)\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eCO]\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eP(O)C\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e5\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\/CSSGPEPIBAPO_structure_160x160.jpg?v=1793437012\" 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 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: 28.0576%; 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\u003e418.47 g\/mol\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\u003eMelt Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 10px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e130 °C – 135 °C\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.0576%;\"\u003e\u003cem\u003eAbsorption Wavelength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%;\"\u003e\n\u003cp\u003e\u003cspan\u003e366 nm–450 nm\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 BAPO powder 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\u003cspan\u003e\u003ca href=\"https:\/\/pubs.acs.org\/aamick\/article-abstract\/14\/38\/43397\/373866\/High-Performance-and-Highly-Safe-Solvate-Ionic?redirectedFrom=fulltext\"\u003eX.
