| Abstract: | A review was given on how to improve high-rate dischargeability of rare earth-based AB 5-type hydrogen-storage alloys. Several ways are valid for improving high-rate dischargeability of AB 5-type hydrogen-storage alloys, such as decreasing cobalt content, deviating stoichiometric proportion, adding some highly electrocatalytic materials, controlling particle-size, modifying surface, etc. |
