| Abstract: | Composite hydrogen storage alloys has developed very quickly during the recent decade. To prepare composite alloys is a effective way to improve electrochemical characteristics of hydrogen storage electrode materials. The sciences of multi-element and multi-phase rare earth composite hydrogen storage al- loys were reviewed. AB5-AB2 type and Mg-based AB5type nano-crystalline composite hydrogen storage alloys were introduced and discussed. Electrochemical properties, composition, and microstructure of these composite material were discussed. Moreover, future prospect in application of composite hydrogen storage alloys is the fundamental research, such as mechanism of composite action, thermodynamic property, etc. |
