Preparation of carbon-metal composite by fluidized-bedspray method and their electrochemical characteristics forthe anode materials of lithium secondary batteries

摘要

Irreversible capacity, charge-discharge capacity and high rate capability of anode of lithiumrnsecondary batteries depends on largely surface characteristics of the carbon. The surface modifiedrnsynthetic graphite which was coated with various metals by fluidized bed spray exhibited thernhigher capacity than that of raw material at high C-rate. The surface modified carbon resulted inrnimproved high rate capability possibly due to decrease in impedance of passivation film.
