Low-temperature synthesized LiV{sub 3}O{sub 8} as a cathode material for rechargeable lithium batteries
- National Univ. of Singapore (Singapore)
LiV{sub 3}O{sub 8} was synthesized at 300--350 C by reaction of Li{sub 2}CO{sub 3} and NH{sub 4}VO{sub 3} which were blended in an aqueous solution. The product was termed LT LiV{sub 3}O{sub 8} and its preparation reaction was studied by thermographic analyses-depolarization thermocurrent. LT LiV{sub 3}O{sub 8} showed a high discharge capacity of 300 mAh/g active material, and maintained a capacity of 275 mAh/g after 15 cycles. Its electrochemical behavior as a cathode material for rechargeable lithium batteries was studied by galvanostatic charge-discharge and cyclic voltammetry. The structure and morphology of LT LiV{sub 3}O{sub 8} were characterized by infrared, X-ray diffraction, scanning electron microscopy, and their relationships with good electrochemical performance were studied.
