能源光电转换与大规模储能二次电池关键材料的研究进展

The excessive use of fossil energy has triggered a series of serious environmental problems, which may bring very serious environmental damage before the depletion of fossil energy. The developments of clean new energy and the matched new technologies for efficient energy storage are of great significance. Solar energy is environmentally friendly and inexhaustible. "Photovoltaic + Energy Storage" will be the most promising solution to the energy problem. After years of research, perovskite solar cells have been recognized as the most promising systems, but their stability and environmental issues need to be addressed urgently. In terms of energy storage, expanding the traditional lithium-ion battery into large-scale energy storage must overcome constraints of resource and safety. Sodium-ion battery and aqueous zinc ion battery have great development potential in the field of large-scale energy storage due to their obvious advantages in resources, cost, safety and environmental friendliness. This paper reviews the latest research progress of related key materials, including the perovskite materials, key cathode and anode materials for sodium/zinc ion batteries, in the hope of providing guidance for the development of high-quality perovskite solar cells and large-scale energy storage secondary batteries with low-cost, high-energy, and long-life through the analysis of the intrinsic relationships among material composition, structure, and performance.
