HCPK (1-Hydroxycyclohexyl Phenyl Ketone, Irgacure 184, >99.5%) as Photoinitiator for Solid-State & Gel Polymer Electrolytes (GPEs), 50-200 g/bottle, CSSGPEPIHCPK

Its functional roles in GPEs synthesis are: (1) Rapid In Situ UV-Gelation in Sealed Cells: HCPK enables the rapid 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) Elimination of Thermal Stress & Side Reactions: 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) High Interfacial Uniformity: Because HCPK dissolves uniformly into 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 (>10^{-3} S/cm).
