Abstract Titanium is well known as a light-weight hydrogen storage material that is applied as a component of hydrogen storage composites together with Mg and other metals. Amorphous boron, boron nitride, and graphite were used as additives to improve Ti-H 2 reactivity during ball-milling due to its anti-sticking and matrix-forming properties.
