    Abstract: Nanocomposites of conductive, nanoparticulate polymer and electronically active material, in particular PEDOT and LiFePO4, were found to be significantly better compared to bare and carbon coated LiFePO4 in carbon black and graphite filled non conducting binder. The conductive polymer containing composite outperformed the other two samples. The performance of PEDOT composite was especially better in the high current regime with capacity retention of 82% after 200 cycles. Further improvement can be obtained if the porosity of the nanocomposites is enhanced. Hence an electrode produced from a composite made of conductive, nanoparticulate polymer, electronically active material, and sacrificial polymer, wherein the sacrificial polymer has been removed leaving pores has improved electrolyte and ion diffusion properties allowing the production of thicker electrodes.
