Superconducting magnetic energy storage (SMES) systems are emerging as efficient solutions for modern energy storage needs, offering rapid response, high power density, and minimal energy losses. This research reviews the role of superconducting materials in energy storage, focusing on their critical properties and phase transition behaviors. High-temperature superconductors (HTS) are highlighted as suitable candidates due to their higher critical current density and lower cooling requirements, while low-temperature superconductors (LTS) remain relevant for specific applications requiring stable performance. Phase transition studies reveal that materials with second-order transitions ensure stable superconducting states under operational stress, enhancing system reliability. Challenges such as mechanical brittleness, high fabrication costs, and cryogenic complexities are identified as barriers to commercialization. Understanding these material behaviors and phase transitions is essential for designing stable, cost-effective SMES systems. This literature-based analysis emphasizes that combining advanced material engineering and controlled phase transitions will drive future energy storage innovations.
