The Study of Theoretic Coated Carbon Amount and Excess Lithium in LiFePO₄/C Synthesis by Means of Carbon Thermal Reduction Route

Abstract:

LiFePO₄/C(LFP/C) composite cathode material was synthesized by carbon thermal reduction route with the sucrose as reducing agent and characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). Some parameters were optimized by means of determining the amount of sucrose and Li₂CO₃. The electrochemical performances were also tested through assembling batteries. The experimental results demonstrated that the proper theoretic coated carbon amount was 11.4% and 4.21% respectively, and the proper lithium usage is the normal stoichiometric proportion, namely, the lithium amount is not excess.
