| Abstract: | In this paper, the influence of heat treatment on the electrochemical properties of a Re-Mg based multi-phase Re 0.92 Mg 0.08 Ni 2.81 Mn 0.10 Co 0.51 Al 0.11 hydrogen storagealloy has been studied. Theresults show that the discharge capacity and cyclic sta- bility have been improved markedly. The discharge capacity of the alloy annealed at 1173 K is the highest, and the cycle life of the alloy annealed at 1173 K is also the longest. |
