TECHNICAL SUMMARYThis research project, supported by the Solid State and Materials Chemistry (SSMC) program will develop direct electrodeposition of crystalline transition metal antimonides, a class of materials that exhibit a wide range of physical properties critical to many advanced technologies. A central focus of this work is on developing robust preparations of materials for high capacity anodes in Li-ion batteries. The high-temperature methods traditionally used to synthesize the target compounds are plagued by lack of control over the stoichiometry of the final products. Electrodeposition, in contrast, is a low-temperature method, which will lead to greater control over the stoichiometry and hence, improved physical properties. The ultimate goal is the direct electrodeposition of a range of anode materials from water at room temperature. The resulting films and nanowires will be directly deposited onto a current collector with no need for binders prior to battery testing. The outreach portion of this proposal will focus on adding renewable energy (in the context of transportation) to the popular Harry Potter based outreach shows that the undergraduate Chemistry Club at Colorado State University has already developed. By building on a wildly successful program, the proposed outreach will reach a wider range of students with an approach that promises to have high impact.NON-TECHNICAL SUMMARYThe goal of this research program is the development of robust synthetic methods for materials with applications as anodes in Li-ion rechargeable batteries. The synthetic approach chosen, electrodeposition, is amenable to industrial scale production, is inexpensive, and can be performed in nontoxic solvents such as water. The direct result of the integrated research and teaching goals proposed will be manifested in the quality of training that graduate and undergraduate students obtain, both in the synthesis and characterization of materials critical to state-of-the-art energy research and in curriculum development and mentoring in the context of the proposed outreach shows. State-of-the-art research is crucial for recruiting and retaining a talented, diverse group of students. The shows described in the education section of this proposal will be used to increase the knowledge base of and excitement for science and renewable energy for fourth and fifth grade elementary school children throughout Colorado.

该研究项目由固态和材料化学（SSMC）计划支持，将开发晶体过渡金属锑化物的直接电沉积，这是一类对许多先进技术至关重要的材料，具有广泛的物理特性。这项工作的中心重点是开发用于锂离子电池中高容量阳极的材料的稳健制备。传统上用于合成目标化合物的高温方法受到缺乏对最终产物的化学计量的控制的困扰。相比之下，电沉积是一种低温方法，这将导致对化学计量的更大控制，从而改善物理性能。最终目标是在室温下从水中直接电沉积一系列阳极材料。 所得的薄膜和纳米线将直接沉积在集电器上，在电池测试之前不需要粘合剂。该提案的推广部分将侧重于将可再生能源（在交通运输方面）添加到受欢迎的哈利波特基础推广活动中，这表明科罗拉多州立大学的本科生化学俱乐部已经发展起来。 通过建立在一个广泛成功的计划，拟议的推广将达到更广泛的学生与方法，有希望有很高的影响力。非技术总结本研究计划的目标是开发强大的合成方法的材料与应用程序作为阳极的锂离子可充电电池。选择的合成方法，电沉积，适合工业规模生产，是廉价的，并且可以在无毒溶剂如水中进行。 提出的综合研究和教学目标的直接结果将体现在研究生和本科生获得的培训质量，无论是在合成和表征的材料至关重要的国家的最先进的能源研究和课程开发和指导的背景下，拟议的推广显示。最先进的研究对于招募和留住有才华的多元化学生群体至关重要。 本提案教育部分所述的节目将用于增加整个科罗拉多四年级和五年级小学生对科学和可再生能源的知识基础和兴奋。
