Olivine structured LiFePO4 thin films were prepared by pulsed laser deposition and their electrochemical properties were investigated by cyclic voltammetry (CV) and charge-discharge tests. The resultant films exhibited only a couple of anodic and cathodic peaks at similar to 3.4 V, which is characteristic of olivine LiFePO4, on CV between 2.0 and 5.0 V (vs. Li/Li+). The discharge capacity estimated from the CV obtained at 100 mV s(-1) maintained 69% of that obtained at 1 mV s(-1). This high rate capability is probably due to the film being so thin that the intrinsically poor electronic conductivity of LiFePO4 was not of importance. (C) 2004 The Electrochemical Society.
