Kopsavilkums

Abstract: LiFePO₄/C/reduced graphene oxide (rGO) composites with different morphologies were synthesized, allowing evaluation of the electrochemical performance as a function of the sample morphology. LiFePO₄ particles anchored on rGO sheets and rGO sheets wrapping LiFePO₄ agglomerations were two of the most pronounced features observed. The structure with LiFePO₄ particles anchored on rGO sheets was found to be the most optimal and give rise to both increased capacity and improved rate capability.
