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

9724792这个美国-巴西奖项将支持怀俄明大学的Daniel Buttry博士与圣保罗大学的Roberto M.Torresi教授和Susana Cordoba Torresi教授之间的研究合作。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定义最大限度地利用锂电池充放电速度的材料和条件。具体地说，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，已被证明在某些条件下具有极高的能量密度，这些条件与用作锂电池的正极材料相关。这项研究不仅对对便携式电源的需求日益增加的工业很重要，而且对社会向电动汽车转变的预计需求也很重要。怀俄明大学实验室专门从事电化学石英晶体微天平方法、光谱电化学(EQCM)薄膜分析方法以及PAN/DMcT体系的复杂化学。圣保罗大学的实验室拥有合成新的导电聚合物衍生物的技能，并将EQCM与其他测量方法结合使用。双方带来的专业知识都是独一无二的，对项目至关重要。***

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. ***
