Enhancing energy storage properties via controlled insulation properties of PVDF-based polymer capacitors
In the realm of energy storage and electrical insulation, this study illuminates the innovative fabrication and consequent properties of polyvinylidene fluoride (PVDF) and polyethylene glycol (PEG800) blend films, synthesized via the casting method. The essence of this research lies in the integration of PEG800 into the PVDF matrix, a strategic move that significantly bolsters the insulation capabilities of the resulting composite, underscored by a dramatic decrease in leakage current from 2.61E-7 A to 3.50E-9 A at an electric field of 50 MV/m. Notably, at an optimal PEG800 mass fraction of 30 %, the composite film unveils an extraordinary energy storage density of 34.6 J/cm3 under the formidable electric field of 650 MV/m. This study not only shows cases the superior energy storage and rapid charge-discharge characteristics, particularly with a discharge time (t0.9) of 66 ns of the 70PVDF/30PEG800 film, but also underscores the potential of such blend films in revolutionizing the design and functionality of polymer film capacitors, marking a significant stride towards sustainable and efficient energy storage solutions.
