The paper presents an overview of the phenomenon of high-temperature superconductivity, which was first discovered in 1986. It describes the most significant achievements, including the overcoming of the liquid nitrogen temperature threshold (77 K) in cuprate superconductors and the achievement of record-breaking critical temperatures in high-pressure hydrides. The paper also discusses the main obstacles to the practical application of high-temperature superconductivity, such as the lack of a unified theoretical model, technical challenges in producing materials with the desired mechanical and electrical properties, high costs, and requirements for cooling systems. Further research is being conducted to find substances that can superconduct at room temperature and normal pressure, and areas where a breakthrough in HTS could lead to significant technological effects, such as energy, transportation, medicine, and information technology.
