Press Release 09-185
For Future Superconductors, a Little Bit of Lithium May Do Hydrogen a Lot of Good

Study suggests strategies for converting hydrogen to metal at significantly lower pressures

Ball-and-stick image of hypothetical metallic crystal cells composed of one lithium, or Li, atom and six hydrogen, or H, atoms. The lithium-hydrogen compound is predicted to form under approximately 1 million atmospheres, which is one-fourth the amount of pressure required to metalize pure hydrogen. The pressure at sea level is one atmosphere and the pressure at the center of the Earth is around 3.5 million atmospheres. Li atoms are green and H atoms are white.
