Abstract Inhibiting the agglomeration of molten aluminum particles packed in binder network is a promising scheme to achieve efficient combustion solid propellants. In this investigation, hydroxyl‐terminated structured fluorinated alcohol compound (PFD) was introduced modify traditional polyethylene glycol/polytetrahydrofuran block copolymerization (HTPE) binder; that is, unique polyether (FTPE) synthesized by embedding organic segments into HTPE via crosslinking curing. The FTPE applied aluminum‐based propellants for first time. Due complete release active range 300°C 400°C, burning rate FTPE‐based propellant increased from 4.07 (0% PFD) 6.36 mm/s (5% PFD), 56.27% under 1 MPa. reaction heat 5.95 7.18 MJ/kg 3.0 MPa, indicating modified with PFD would be conducive inhibiting D 90 condensed products (CCPs) dropped 81.84% 75.46 13.71 μm consistent significant reduction agglomerates observed on quenched surface Those results demonstrated novel can segments, which motivate preignition alumina shell early stage combustion, and then enhance melting diffusion effect inhibit agglomeration.

Electrolytic Ni-P and Ni-P-Cu Coatings on PCM-Loaded Expanded Graphite for Enhanced Battery Thermal Management with Mechanical Properties

Materials, Год журнала: 2025, Номер 18(1), С. 213 - 213

Опубликована: Янв. 6, 2025

This study addresses the thermal management challenge in battery systems by enhancing phase change material composites with Ni-P and Ni-P-Cu coatings on material/expanded graphite structures. Traditional materials are limited low conductivity mechanical stability, which restricts their effectiveness high-demand applications. Unlike previous studies, this work integrates to significantly improve both strength of composites, filling a crucial gap solutions. The results reveal that Ni-P-Cu-coated exhibit superior 27.1 W/m·K, outperforming uncoated Ni-P-coated counterparts. Mechanical testing showed coating provided highest compressive at 39.4 MPa enhanced tensile due coating’s highly crystalline structure smaller grain size. Additionally, phase-change characteristics transition temperatures between 38 °C 43 °C, allowed effective heat absorption, stabilizing under 1.25C 2.5C discharge rates. Voltage decay analysis indicated reduced polarization effects, extending operational stability. These findings suggest applications, especially where efficient dissipation durability critical for performance safety. offers promising approach improving energy storage applications such as electric vehicles, grid storage, portable electronics.
