Dielectric relaxation spectroscopy (DRS) is a powerful technique for characterizing the electrical properties of materials, particularly in the frequency range of 50 Hz to 1 MHz. In this study, we employ DRS to investigate the dielectric properties of a composite material composed of polyvinyl alcohol-polyvinylpyrrolidone (PVA-PVP) and nickel-cadmium (Ni- Cd) particles, which are commonly used in battery manufacturing. The dielectric relaxation behavior of the composite is analyzed over the frequency range of interest, and the results are correlated with the microstructure and composition of the material. The influence of processing parameters such as temperature and pressure on the dielectric properties is also investigated. Our findings provide valuable insights into the electrical behavior of battery manufacturing materials and can inform the design and optimization of battery systems. The results of this study have implications for the development of high-performance batteries with improved energy storage and charging capabilities.
