摘要

Abstract

A facile and practical route was introduced to prepare LiFePO

/C cathode material with nano-sized primary particles and excellent electrochemical performance. LiH

was synthesized by using H

and LiOH as raw materials. Then

as-prepared LiH

reduced iron powder and α-D-glucose were ball-milled

dried and sintered to prepare LiFePO

/C. X-ray diffractometry was used to characterize LiH

ball-milled product and LiFePO

/C. Differential scanning calorimeter-thermo gravimetric analysis was applied to investigate possible reactions in sintering and find suitable temperature for LiFePO

formation. Scanning electron microscopy was employed for the morphology of LiFePO

/C. As-prepared LiH

is characterized to be in P21cn(33) space group

which reacts with reduced iron powder to form Li

(PO

)

and H

in ball-milling and sintering. The appropriate temperature for LiFePO

/C synthesis is 541.3-976.7℃. LiFePO

/C prepared at 700℃ presents nano-sized primary particles formin

g aggregates. Charge-discharge examination indicates that as-prepared LiFePO

/C displays appreciable discharge capacities of 145 and 131 mA·h·g

-1

at 0.1 and 1 C respectively and excellent discharge capacity retention.
