Abstract
Owing to the urgent global demand for carbon emission reduction and enhanced energy efficiency, advanced semiconductor power devices in the electric vehicle (EV) industry have been increasingly adopted, and significant improvements in energy efficiency and the miniaturization of EV electrical systems have been made. A key component in this technological evolution is the polymer film capacitor, characterized by its high-voltage, high-frequency, and high-reliability performance, which makes it pivotal for advanced EV electrical systems. This review explores the critical role of polymer film capacitors in EV traction and charging systems, and by analyzing their operational principles, identifies the unique challenges faced by the energy storage polymers in capacitors developed for these applications. A systematic review of the research focused on enhancing the performance of energy storage polymers, with a goal of increasing the dielectric constant, improving the breakdown strength, optimizing structural designs, and modulating charge carriers, is also provided. Furthermore, this review highlights the discrepancies between industrial-scale manufacturing and laboratory fabrication. This study concludes with an assessment of several innovative laboratory preparation methods and strategies that have potential in scale-up production, mapping new trajectories for research aimed at optimizing polymer film capacitor dielectrics for EV applications.
期刊介绍:
Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications.
The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms.
Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC).
Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
