Abstract

Nanocomposits of conductive, nanoparticulate polymer and electronically active material, in particular PEDOT and LiFePO, were found to be significantly better compared to bare and carbon coated LiFePOin 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. Hence an electrode based on composite made of conductive, nanoparticulate polymer and electronically active material, in particular LiFePOand PEDOT nanostubs, with its higher energy density and increased resistance to harsh charging regimes proved to dramatically extend the high power applicability of materials such as LiFePO.
