U.S.-Brazil Cooperative Research: Enhanced Power Density in Polymeric, Thin Film Battery Materials

这项美国-巴西奖将支持怀俄明大学的丹尼尔·布特里博士与圣保罗大学的罗伯托·m·托雷西教授和苏珊娜·科尔多瓦·托雷西教授之间的一项研究合作。他们的合作是提高聚合物薄膜电池材料的功率密度。这两个研究实验室希望共同努力，确定材料和条件，使锂基电池的充放电速率最大化。具体来说，他们正在研究聚苯胺（PAn）催化氧化2,5-二巯基-1,3,4-噻二唑（DMcT）氧化还原过程的机理。这是一种薄膜混合物，在特定条件下具有极高的能量密度，可以用作锂电池的正极材料。这项研究不仅对工业来说很重要，因为工业对便携式电源的需求越来越大，而且对社会转向电动汽车的预计需求也很重要。怀俄明大学实验室专门研究电化学石英晶体微天平方法，光谱电化学（EQCM）方法分析薄膜和Pan/DMcT系统的复杂化学。圣保罗大学实验室拥有新的导电聚合物衍生物的合成技能，并将EQCM与其他测量方法结合使用。双方的专业知识对项目来说都是独一无二的。＊＊＊

9724792 Buttry This U.S.-Brazil award will support a research collaboration between Dr. Daniel Buttry of the University of Wyoming to work with Professors Roberto M. Torresi and Susana Cordoba Torresi at the University of Sao Paulo. Their collaboration is on enhanced power density in polymeric, thin film battery materials. These two research labs want to work together to define materials and conditions that make the most of charging and discharging rates of lithium-based batteries. Specifically they are looking at the mechanism of the polyaniline (PAn) catalyzed oxidized 2,5-dimercapto-1,3,4-thiadiazole (DMcT) redox process. This is a thin-film mixture that has been shown to have extremely high energy density under certain conditions that are relevant to use as a cathode material in a lithium battery. This research is important not only for industry, which has an increasing need for portable power sources, but also for the projected need for society's conversion to electric vehicles. The University of Wyoming lab specializes in electrochemical quartz crystal microbalance methodology, in spectroelectrochemical (EQCM) methods of analyzing thin films and in the complex chemistry of the Pan/DMcT system. The University of Sao Paulo lab possesses skill in the synthesis of new conducting polymer derivatives and in using the EQCM in conjunction with other measurement methods. The expertise brought by each side is unique and essential to the project. ***
