Research of LiMnPO₄/C Synthesized by Solid-State Reaction with Different Carbon Sources

Abstract:

The carbon-containing LiMnPO4 compounds were prepared by solid-state reaction with different carbon source: carbon black, citric acid, sucrose, or resorcinol formaldehyde resin. The structure, surface morphology and electrochemical performance of LiMnPO4 were characterized by X-ray diffractometry, scanning electron microscopy and electrochemical measurement respectively. The AC impedance and Cyclic Voltammetry was also discussed. The results showed that the electrochemical performance of LiMnPO4/C was affected by different carbon source. The particle size of LiMnPO4/C using resorcinol formaldehyde resin as carbon source was about 100~300 nm. The initial discharge capacity is 121.6mAh/g at 0.02C and an overall reversible capacity of 110mAh/g has been retained after 20 cycles. While at 0.1C, the discharge capacity was 110mAh/g; and more than 60mAh/g at 1C.
