High-performance Mn-Zn and Ni-Zn ferrites, amorphous, nanocrystalline, and metamaterials have been developed rapidly in recent years to meet the electromagnetic characteristics requirements of WPT systems. This paper begins with a comprehensive review of the magnetic materials used in WPT systems and concludes with cutting-edge WPT technology and the development and application of high-performance magnetic materials. Furthermore, this study provides an exclusive resource for researchers and engineers interested in learning about the technology and highlights critical issues that must be addressed. Finally, the potential challenges and opportunities of WPT magnetic materials are presented, and the technology's future development directions are predicted and discussed.
Because of its high transmission efficiency and acceptable transmission distance, the magnetic coupling resonant wireless power transfer (MCR-WPT) system is regarded as the most promising wireless power transfer (WPT) method. Magnetic cores made of magnetic materials are typically added to MCR-WPT systems to improve coupling performance in order to achieve magnetic concentration. However, as WPT technology advances, traditional magnetic materials gradually become a bottleneck, limiting system power density enhancement.
