Catalyst Design for Isotactic Polycarbonates as Lithium-Ion Transport Membranes

化学系支持康奈尔大学的William Ellis成为美国化学竞争力研究员。Ellis博士将致力于开发用于环氧化物和二氧化碳共聚的锌基催化剂。他将与加州伯克利电池公司SEEO的科学家合作。本研究的最终目标是开发聚碳酸酯高等规聚碳酸酯材料，用于锂离子电池的锂离子传输膜材料。对于他扩大参与的计划，PI将开发一套动手科学工具包，让农村学生参与科学。在这项活动中，PI将与康奈尔材料研究中心的教育工作者合作。像埃利斯博士这样的研究旨在开发锂离子电池的新型材料，锂离子电池是一项越来越重要的技术。埃利斯博士正在开发的这种特殊化学物质是“绿色”的，因为它使用了一种富含地球的元素（锌）作为催化剂中的过渡金属，这种元素的毒性很低，而他的原料化学物质之一是二氧化碳。埃利斯博士所追求的扩大参与的努力旨在让农村地区代表性不足的学生在重要的科学领域进行实践活动。

The Division of Chemistry supports William Ellis of Cornell University as an American Competitiveness in Chemistry Fellow. Dr. Ellis will work on developing Zn-based catalysts for the copolymerization of epoxides and carbon dioxide. He will collaborate with scientists at SEEO, a Berkeley, California-based battery company. The ultimate goal of this research is to develop polycarbonate highly isotactic polycarbonate materials for use as lithium-ion transport membrane materials in Li ion batteries. For his plan for broadening participation, the PI will develop a hands-on science kits to engage rural students in science. In this activity, the PI will collaborate with educators at the Cornell Center for Materials Research.Research like that of Dr. Ellis is aimed at developing new kinds of materials for lithium ion batteries, an increasingly important technology. The particular chemistry that Dr. Ellis is developing is "green" in that it uses an earth-abundant element (zinc) that has low toxicity as the transition metal in his catalysts, and one of his feedstock chemicals is carbon dioxide. The efforts at broadening participation being pursued by Dr. Ellis are aimed at giving underrepresented students in rural areas hands-on activities in important areas of science.
