Abstract  

This study was concerning the carbonation and modification of carbon coating method of LiFePO4. The structure and the electrochemical performance were characterized by TG-DTA, XRD, TEM and electrochemical performance testing. The results showed that different molecular weights and structures of the carbon sources resulted in different decomposition temperatures and structures of carbonized products, and the electrochemical performance of the LiFePO4/C composite materials was effected by different carbon sources also.

Key words:  inorganic non-metallic materials      lithium iron phosphate      co-precipitation method      carbon-coating in suit      carbonation
