Preparation of LiFePO[sub 4] Thin Films by Pulsed Laser Deposition and Their Electrochemical Properties

Abstract

Olivine structured 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 which is characteristic of olivine on CV between 2.0 and 5.0 V (vs. The discharge capacity estimated from the CV obtained at maintained 69% of that obtained at This high rate capability is probably due to the film being so thin that the intrinsically poor electronic conductivity of was not of importance. © 2004 The Electrochemical Society.
