| Abstract: | Optimizing the rare earth composition and doping with boron have been used to improve the low temperature performance of AB 5 hydrogen storage alloy.The results show that Ce-rich alloy with a proper amount of boron is suitable for Ni/MH battery with the lower-limit temperature down to 238 K under smaller current density (120 mA/g). The improvement of low temperature performance of hydrogen storage alloy is well consistent with its microstructure,thermodynamic and kinetic properties. |
