NEGATIVE-ELECTRODE MATERIAL, NEGATIVE-ELECTRODE ACTIVE MATERIAL, NEGATIVE ELECTRODE, AND ALKALI METAL ION BATTERY |
| 摘要 |
A negative-electrode material of the present invention is a carbonaceous negative-electrode material used for an alkali metal ion battery and an average layer spacing d002 of face (002) calculated by an X-ray diffraction method using CuKα radiation as a radiation source is equal to or greater than 0.340 nm. The halogen content of the negative-electrode material of the present invention is equal to or greater than 0.5 ppm and less than 50 ppm. |
