新型R-Mg-Ni（R：稀土）超晶格合金具有比传统的CaCu_5结构的Mm-Ni合金更高的容量和更高的耐久性。通过优化合金成分，如以铝代镍、优化镁含量等来提高超晶格合金的氧化稳定性，以延长电池寿命。通过使用改进的超晶格合金作为负极材料，已经开发并商业化了用于零售市场的高容量镍-金属氢化物电池，Ni-MH 2500/900系列（AA尺寸类型2500 mAh，AAA尺寸类型900 mAh）。
New R–Mg–Ni (R: rare earths) superlattice alloys with higher-capacity and higher-durability than the conventional Mm–Ni alloys with CaCu5structure have been developed. The oxidation resistibility of the superlattice alloys has been improved by optimizing the alloy composition by such as substituting aluminum for nickel and optimizing the magnesium content in order to prolong the battery life. High-capacity nickel-metal hydride batteries for the retail market, the Ni-MH2500/900 series (AA size type 2500mAh, AAA size type 900mAh), have been developed and commercialized by using an improved superlattice alloy for negative electrode material.
