The development of electrode materials that exhibit both exceptional electrochemical and mechanical properties is increasing in importance. Such a material would enable the development of electrodes for energy and power that can dissipate energy, bear a load, or withstand an impact. In this presentation, we report on a composite electrode containing polyaniline, graphene, and Kevlar�, fabricated via layer-by-layer assembly for use as a cathode in a non-aqueous battery. Polyaniline, a conjugated polymer, is widely used as a polymer electrode material since it has good electrical conductivity and chemical stability. Graphene has also good electrical properties and mechanical strength due to its unique two-dimensional structure. In addition, Kevlar is of interest for its high mechanical strength. Film growth, structure, and morphology are characterized using scanning electron microscopy, and UV-vis spectroscopy, Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy. Electrochemical and mechanical performance are evaluated for the first time.
