Title:
CARBONACEOUS MATERIAL, ELECTRODE MATERIAL USING SAME, AND BATTERY
Document Type and Number:
WIPO Patent Application WO/2018/143123
Kind Code:
A1
Abstract:
The carbonaceous material according to the present invention has a crystal structure in which the <002> spacing as determined via wide-angle X-ray analysis is 3.40–3.60 Å, the crystallite sizes in the c-axis direction are 15–150 Å, and the crystallite sizes in the a-axis direction are 25–75 Å, and, in a spectrum obtained via laser Raman spectroscopy at an excitation wavelength of 532 nm, the intensity ratio (ID/IG) of the peak intensity (ID) near 1360 cm–1 and the peak intensity (IG) near 1580 cm–1 is 0.2–2.0, and the Ti content as determined via ICP spectrometry is 0.1–30% by weight.
