中文摘要	Hard carbon was coated with conducting polymers via in-situ polymerization and its electrochemical performance as an anode for lithium ion batteries was investigated. SEM,Raman spectroscopy, conductivity and the constant-current charge-discharge properties of original and treated hard carbon were studied. Results showed that hard carbon can be easily coated by conducting polymers. The conductivity of hard carbon coated by polythiophenes increased. The initial charge capacity of the coated hard carbon was as high as 384. 7 mAh g/sup -1/ , which was higher than 320. 3 mAh g/sup -1/ of untreated hard carbon. The capacity of the coated hard carbon remained higher than 325 mAh g/sup -1/ even after 20 cycles, while that of untreated hard carbon was lower than 290 mAh g/sup -1/ .
