The energy storage density of 0.75 vol.% NBT/PVDF composite material reaches 13.78 J/cm 3 at an electric field intensity of 380 kV/mm, which is about 1.87 of pure PVDF, and
What is the energy storage density of NBT/PVDF?
At 220 kV/mm electric field strength, the maximum energy storage density of 15 wt% NBT/PVDF is about 2.58 J/cm 3, which is 23.4% higher than that of pure PVDF, and its charge–discharge efficiency is 52%. However, when the filler mass fraction continues to increase, the energy storage efficiency of the film decreases somewhat.
How to modulate energy storage density in PVDF films?
In a word, the nature of modulating energy storage density is to vary the composition of different phases in PVDF films. Quenching, stretching, and annealing are recognized to be effective ways to provide crystallization modification for PVDF materials.
What is the maximum discharge energy density of PVDF?
The maximum discharge energy density is about 2.58 J/cm 3, which is 1.3 times higher than that of pure PVDF, and the charging and discharging efficiency is about 52%.
Does hot-pressing temperature affect energy storage performance of PVDF films?
The improvement of crystallinity can promise higher maximum polarization, which is beneficial for the enhancement of energy storage density. This work can provide us with the influence law about how hot-pressing temperature affects the energy storage performance of PVDF films and guide us to do further researches.
Can PVDF-based polymer composites be used in energy storage devices?
The various materials used in supercapacitors are studied. It is observed that the usage of PVDF-based polymer composites in energy storage devices is very prospective, and future research into innovative polymer composites and ways to enhance their properties might be considerable.
What is the energy storage density of BST/PVDF composites?
Li Wang et al. obtained the highest of 4.10 J/cm 3 energy storage density at hot pressing temperature 12 0 0 C for BST/PVDF composites containing 40 vol% BST, which was 3.33 and 1.46 times more than that of the composites at room temperature (1.23 J/cm 3) and the neat PVDF matrix (2.8 J/cm 3) .
