Abstract:Metallic conductive PAC 1003, an inherently conductive polymer product of Crosslink, has been developed to have remarkably high electrical conductivity of >1000 S/cm which can be applied to advanced polymer supercapacitor designs. The metallic conductivity of the polymer allows supercapacitors with low equivalent resistance and high capacitance, involving efficient redox electrochemical activity. The use of n-dopable polymers can enhance the function of the supercapacitor, for which higher energy and power densities can be achieved. In parallel efforts, outstanding device structures with strategic technical features comprising nano-structured interfacial layers, leakage free and bipolar device designs have proven to be promising for competitive device performance.
