Abstract

The Zr-based $AB_2$ type Laves phase hydrogen storage alloys have some promising properties, long cycle life, high discharge capacity, as electrode materials in reversible metal hydride batteries. However, when these alloys are used as negative electrode for battery, there is a problem that their rate capabilities are worse than those of commercialized $AB_5$ type hydrogen storage alloys. In this work, we tried to develop the Zr-based $AB_2$ type Laves phase hydrogen storage alloys which have high capacity and, especially, high rate capability.
