Beschreibung
Zusammenfassung:According to the present invention, in the frequency distribution of an R value representing the ratio (G/D) of the peak intensity in a G-band (1580 cm-1) to the peak intensity in a D-band (1360 cm-1) of graphite obtained by Raman mapping measurement, carbonaceous particles for a negative electrode material of a lithium ion secondary battery satisfy conditions (1) and (2). (1) The mode (Rc) of the R value is 0.87-0.96. (2) The R value (R50) when a cumulative frequency from the smaller R value side is 50% is 0.88-0.92.
