Abstract

There is an urgent need to develop next-generation rechargeable batteries for a carbon-neutral society. In this context, our research team is focusing on magnesium, which is abundant in the earth's crust and inexpensive. Ribbons of Mg-9%Al-3%Ca, a magnesium alloy, were prepared as anode material for rechargeable batteries by a single-roll rapid solidification method. The fabricated ribbons were subjected to various manufacturing conditions, and various properties such as surface properties, microstructure, mechanical properties, and electrochemical activity of the fabricated ribbons were evaluated. As a result, it was found that a peripheral speed of 25 m/s and an injection pressure of 0.05 MPa or less were desirable to fabricate ribbons with good surface and mechanical properties. It was also confirmed that electrochemical activity contributes significantly to the orientation of magnesium and that production conditions with a peripheral velocity of 30 m/s or higher resulted in low electrochemical activity.
