This Small Business Innovation Research Phase I project targets the efficient production of rare earth (misch metal) alloys for use in metal hydride battery electrodes. The electrolytic reduction of rare earth oxides will be studied. Deposition characteristics (potential, metal redissolution, sludge formation) of various rare earth components of misch metal will be investigated in Phase I, other aspects in Phase II. The information will be used to design, construct and operate a pilot cell for the production of misch metal with high feed utilization, high current efficiency, high product quality, and the ability to tailor product composition by adjusting feed properties. Availability of an economically attractive process to produce rare earth alloys is expected to lead to their domestic manufacture. This is desirable because their broad use in advanced materials is being projected.

该小型企业创新研究第一阶段项目的目标是高效生产用于金属氢化物电池电极的稀土（混合稀土）合金。将研究稀土氧化物的电解还原。第一阶段将研究混合稀土各种稀土成分的沉积特性（电位、金属再溶解、污泥形成），第二阶段将研究其他方面。这些信息将用于设计、建造和运行混合稀土生产中试单元，该试验单元具有高进料利用率、高电流效率、高产品质量，并且能够通过调整进料特性来定制产品成分。 经济上有吸引力的稀土合金生产工艺的可用性预计将导致其国内制造。这是可取的，因为预计它们将在先进材料中得到广泛应用。
