· CaCu5

CaCu5 is an intermetallic compound in the calcium-copper system, forming a brittle metallic phase with relatively high density. This material belongs to the family of rare-earth-free intermetallics and is primarily of research interest for hydrogen storage applications, where similar calcium-copper phases show promise for absorbing and releasing hydrogen at moderate temperatures and pressures. Industrial adoption remains limited; the material is most relevant to materials scientists exploring next-generation energy storage systems as an alternative to conventional hydride materials, particularly where cost reduction or specific thermal cycling behavior is advantageous.
