NEGATIVE ELECTRODE ACTIVE MATERIAL FOR SODIUM-ION BATTERY, SODIUM-ION BATTERY AND METHOD OF PRODUCING NEGATIVE ELECTRODE ACTIVE MATERIAL FOR SODIUM-ION BATTERY |
摘要 |
A negative electrode active material for a sodium-ion battery includes a negative electrode active material ingredient that is a compound having an aromatic ring structure and two or more COOX groups in which X is Li or Na, and which are bonded to ends of the aromatic ring structure; and a carbon material. The carbon material has an interlayer distance d002 equal to or smaller than 3.5 Å or a D/G ratio equal to or smaller than 0.80, the D/G ratio being obtained by Raman spectrometry. |
