Lithium-ion batteries LIB have been used as power sources of portable electronic devices such as a laptop computer, a celler phone, and so on 1 , 2 . Moreover, LIBs have been expected as power sources of hybrid electric vehicle, plug-in hybrid electric vehicle, and electric vehicle due to their high energy densities.High rate performance, safety, and longer life of LIBs are required for practical use in these EVs. Among the above requirements, we have focused on the rate capabilities of carbonaceous negative electrodes.The rate capabilities of LIBs can be enhanced by the decrease of internal resistances caused by lithium-ion diffusion in active materials and electrolyte, lithium-ion transfer at interface between electrode and electrolyte, electron transfer at interface between current collector and electrode. These processes can be a rate-determining step. At
