Lithium-ion battery (LIB) nowadays plays a key role as one of the most widely used energy storage technologies such application in electric vehicles. Thermal management critically affects performance LIB. Phase change cooling using phase material (PCM) has become promising method due to its high latent heat and no need consume extra pump power. In this study, thermal module with 25-parallel 18650 lithium-ion been numerically experimentally investigated by adopting PCM. Firstly, internal...
A donor–acceptor (D–A) cruciform conjugated luminophore DMCS-TPA was designed and synthesized. The solid shows both aggregation induced emission (AIE) effect high contrast mechanochromic (MC) behavior with a remarkable spectral shift of 87 nm. obvious fluorescence switching from yellowish green to orange can be realized by pressing at only 10 MPa or simply grinding. photophysical properties, theory calculation XPS results demonstrate that the extension conjugation length subsequent...
In light of the intense recent interest in methylammonium lead halides, CH3NH3PbX3 (X = Cl, Br, and I) as sensitizers for photovoltaic cells, dynamics (MA) cation these perovskite salts has been reinvestigated a function temperature via 2H, 14N, 207Pb NMR spectroscopy. cubic phase all three salts, MA undergoes pseudoisotropic tumbling (picosecond time scale). For example, correlation time, τ2, C-N axis iodide salt is 0.85 ± 0.30 ps at 330 K. The are essentially continuous across ↔ tetragonal...
We report a combined solid-state (1H, 2H, 13C, 17O) NMR and plane-wave density functional theory (DFT) computational study of the O···H···O low-barrier hydrogen bonds (LBHBs) in two 1,3-diketone compounds: dibenzoylmethane (1) curcumin (2). In solid state, both 1 2 exist cis-keto–enol tautomeric form, each exhibiting an intramolecular LBHB with short O···O distance (2.435 Å 2.455 2). Whereas numerous experimental (structural spectroscopic) studies have been reported for enol isomers...
Anode materials are critical for energy devices based on Li-ion batteries (LIBs). This work reports a facile method to produce anodes carbon-coated Fe3O4 (CP-Fe3O4) that is encapsulated in reduced graphene oxide (rGO) layers forming porous core–shell structure Fe3O4@carbon (rGO–CP-Fe3O4). First, particles were coated with carbon by hydrothermal and carbothermal reduction methods leading an intermediate product termed CP-Fe3O4. Next, CP-Fe3O4 was two-dimensional layered rGO obtain composites...
Lithium-ion battery heat generation characteristics during aging are crucial for the creation of thermal management solutions. The 21700 (NCA) cylindrical lithium-ion batteries were investigated using mathematical model that was created in this study to couple electrochemical mechanisms, transfer, and loss. These findings indicate that, at same operating current, power cell increased significantly with aging. This increase primarily due energy loss caused by growth solid–electrolyte...
Sodium thioantimonate (Na3SbS4) and its W-substituted analogue Na2.88Sb0.88W0.12S4 have been identified as potential electrolyte materials for all-solid-state sodium batteries due to their high Na+ conductivity. Ball milling mechanochemistry is a frequently employed synthetic approach produce such Na+-conductive solid solutions; however, changes in the structure morphology introduced these systems via process are poorly understood. Herein, we combined X-ray absorption fine spectroscopy,...
The preparation of supertoughening poly(ethylene terephthalate) (PET) blends has always been a practical and valuable task. In our work, PET resins grafted with poly(acrylic acid) (PAA), termed as PET-g-PAA, were first prepared through γ-ray radiation induced graft polymerization blended in partially miscible PET/ethylene-methyl acrylate-glycidyl methacrylate random terpolymer (ST2000) system the compatibilizer. impact strength achieves maximum at 6 wt % but without loss tensile strength....
