Driven by global energy structure transformation and the "dual-carbon" goal, energy materials preparation technology has become a core support for breaking through energy bottlenecks and promoting industrial upgrading. From the efficient utilization of traditional energy sources to the large-scale application of new energy sources, technological innovation in materials preparation directly determines the performance boundaries and commercial prospects of energy technologies, becoming a key indicator for measuring the competitiveness of the energy industry.
Energy materials preparation encompasses diverse technological paths, adapting to the application needs of different energy types. Traditional energy materials preparation focuses on efficient and clean conversion, improving resource utilization and reducing environmental emissions through refined processing techniques. Emerging energy materials preparation, on the other hand, focuses on high performance, low cost, and greenness, exhibiting characteristics of multidisciplinary integration. Thin-film materials preparation utilizes technologies such as evaporation, sputtering, and atomic layer deposition to achieve high-purity and high-uniformity production of photovoltaic modules and energy storage devices; bulk energy storage materials employ processes such as high-temperature solid-state reactions and sol-gel methods to precisely control crystal structures and optimize charge-discharge efficiency and cycle life.
Technological innovation is the core driving force for the iterative upgrading of energy materials preparation. In recent years, breakthroughs have been made in solid-state electrolyte preparation technology. Through doping modification and interface engineering optimization, ionic conductivity and safety have been significantly improved, laying the foundation for high-energy-density energy storage devices. Perovskite material preparation, thanks to process innovations such as laser etching and slot coating, has overcome the stability challenges of large-area mass production, driving continuous record-breaking photovoltaic conversion efficiency. The maturity of nanomaterial and composite material preparation technologies has further achieved synergistic enhancement of material performance; for example, silicon-carbon composite anodes, through structural design, mitigate volume expansion and significantly improve energy storage capacity.
Green and intelligent technologies have become the mainstream of energy material preparation. The high energy consumption and high pollution problems of traditional preparation processes are gradually being solved. Green processes such as low-temperature controllable synthesis and in-situ composite are widely used, significantly reducing energy consumption and pollutant emissions during production. Simultaneously, artificial intelligence and digital twin technologies are integrated into the preparation process, enabling precise control of process parameters and intelligent optimization of equipment operation, effectively improving product consistency and production efficiency, and driving the transformation of the preparation industry from "scale expansion" to "quality improvement."
Currently, energy material preparation still faces challenges such as insufficient equipment adaptability and the difficulty of low-cost large-scale production. In the future, with the deep integration of interdisciplinary technologies, preparation processes will move towards greater precision, efficiency, and environmental friendliness. Continuous breakthroughs in energy material preparation technologies will undoubtedly further unleash the potential of the new energy industry, provide solid technological support for global energy transition, and contribute to building a clean, low-carbon, safe, and efficient energy system.
