MACRO-POROUS GRAPHITE ELECTRODE MATERIAL, PROCESS FOR PRODUCTION THEREOF, AND LITHIUM ION SECONDARY BATTERY

摘要

This invention provides a macroporous graphite electrode material that may be manufactured at a low temperature of 1500° C. or less and may be fast charged and discharged and a manufacturing method thereof. It also provides a lithium-ion secondary battery using this macroporous graphite electrode material. The macroporous graphite electrode material according to this invention is composed of graphite having macropores in which a ratio of specific surface area of micropores in relation to total specific surface area is not less than 0 and not more than 0.74 and a ratio of D band area and G band area in Raman spectrum (D/G area ratio) is not less than 0 and not more than 1.33.
