LITHIUM ION SECONDARY BATTERY CATHODE, BINDER FOR LITHIUM ION SECONDARY BATTERY CATHODE AND LITHIUM ION SECONDARY BATTERY USING THEM

摘要

A lithium ion secondary cell anode, wherein carbon material including graphite having a d002 of not more than 0.3370nm of X-ray parameters that can be obtained from the Gakushin-method for X-ray diffraction of carbon is used as a part of an active material, and a macromolecular material having a surface energy gamma S of not less than 30mJm<-2> is used as a binder.
