| Abstract: | AB 5 type hydrogen storage alloys are widely used as negative material of MH/Ni battery.The electrochemical properties of hydrogen storage alloys are determined by the component of the alloys,microstructure and surface states.The effects of preparation technology of AB 5 type hydrogen storage alloys on the electrochemical properties were summarized.It is shown that preparation technology exerts great influence on homogenization and microstructure of the hydrogen storage alloys.However,the most effective way to obtain high capacity,long cycle life and low cost hydrogen storage alloys is to optimize the alloy components and use the better preparation technology. |
