A Sandia-led team has developed a way to make a magnetic material that could lead to lighter1 and smaller, cheaper and better-performing high-frequency transformers, needed for more flexible energy storage systems and widespread adoption2 of renewable energy. The work is part of a larger, integrated portfolio3 of projects funded by Department of Energys Energy Storage Program in the Office of Electricity Delivery and Energy Reliability4.Transportable energy storage and power conversion5 systems, which can fit inside a single 百度竞价推广i-trailer, could make it cosplayt effective to rapidly install solar, wind and geothermal energy systems in even the most remote locations.Such modular systems could be deployed6 quickly to multiple sites with much less as百度竞价推广bly and validation7 time, said Sandia researcher Todd Monson of Nanoscale Sciences Department, who led the team with Stan Atcitty of Sandias Energy Storage Technology Systems Department.Sandia manufactures iron nitride powders by ball-milling iron powders in liquid nitrogen and then ammonia. The iron nitride powders are then consolidated8 through a low-temperature field-assisted sintering technique that forms a solid material from loose powders through the application of heat and sometimes pressure.The FAST manufacturing method enables the creation of transformer cores from raw starting materials in minutes, without decomposing9 the required iron nitrides, as could happen at the higher temperatures used in conventional sintering. Previously10, the phase of iron nitride has only been synthesized in either thin-film form in high-vacuum environments or as inclusions in other materials, and never integrated into an actual device.Monson said using this method could make transformers up to 10 times smaller than they are currently.
