采用气体雾化法制备球形储氢合金粉末（AB 5型合金）。将合金粉末与片状Ni粉末混合，然后加压成型以制成电极。在100 A/kg的电流密度下进行充电/放电循环测试。将球形合金粉末致密地填充到电极中，实现了1800 Ah/L的每体积电极的最大容量。讨论了镍粉和贮氢合金粉的形状效应。
Gas-atomizing method was used to fabricate sphere-shaped hydrogen storage alloy powder (AB5 type alloy). The alloy powder was intermixed with flake-shapes Ni powder, followed by pressure-molding to make electrode. Charge/ discharge cycle test was conducted at current density of 100A/kg. The spherical alloy powder was packed densely into the electrode, achieving a maximum capacity per volume of electrode of 1800 Ah/L. The shape effect of the nickel powder and hydrogen storage alloy powder was discussed.
