Core Viewpoint - The research team from the Shenyang National Laboratory for Materials Science has developed a "flash annealing" process that can achieve heating and cooling rates of up to 1000 degrees Celsius per second, enabling the production of wafer-level high-performance energy storage films, which opens new pathways for the manufacturing of next-generation high-performance energy storage capacitors [1][2]. Group 1 - The "flash annealing" process allows researchers to fabricate a type of film called lead zirconate on silicon wafers in just one second, freezing the material's special structure at room temperature and forming nano-microdomains smaller than 3 nanometers, which are crucial for inducing relaxor ferroelectric behavior and achieving high-efficiency energy storage [2]. - The process enhances the film's texture, making it denser and more uniform, while effectively locking in volatile lead elements, significantly reducing material defects and leakage current [2]. - Capacitors made using this technology demonstrate excellent environmental adaptability, with minimal degradation in energy density and efficiency (less than 3%) after exposure to extreme temperatures ranging from -196 degrees Celsius to 400 degrees Celsius, indicating stable and reliable performance in various harsh environments [2]. Group 2 - Researchers have successfully produced uniform high-performance films on 2-inch silicon wafers, providing an industrially viable solution for chip-level integrated energy storage [2].
