The Stanford University team will additively manufacture amorphous metal SMCs with near-net shapes, reduced cost, reduced material waste, and tailored properties. SMCs are key to increasing energy density and efficiency of electric motors and enabling miniaturized electric vehicle chargers, transformers, and power generators. Scalable, solution-processed oxide-coated amorphous metal nanoparticles will be 3D-printed into rods and donut shapes (toroids) for magnetic measurements. SMC inductor performance will be tested within a calorimetric chamber for precise measurement of losses. If successful, the team’s efforts would result in magnetic cores with 10x lower core loss at frequencies of 500 kHz to 1 MHz at half the price of state of the art.
SMC technology vastly simplifies complex manufacturing steps, which would lead to cheaper, less expensive, and more powerful energy storage devices and power converters.
