Synthesis of LiFePO4 nanoparticles and electrochemical studies at full-cell level

Abstract

LiFePO₄ nanoparticles have been successfully obtained by a solid-phase synthesis method using nanoscaled FePO₄ as starting materials. Three-electrode system using as-prepared LiFePO₄ as cathode was assembled to monitor the variation of voltage and impedance in the anode or cathode. The pouch-typed cells with prepared LiFePO₄ were assembled to investigate electrochemical performance at level of full-cell. The results show that the assembled pouch-typed full-cells present higher power density and favorable cycle life.
