Aqueous negative electrode material and a manufacturing method thereof for electrolyte secondary battery, and a nonaqueous electrolyte for a secondary battery negative electrode and a non-aqueous electrolyte secondary battery

PROBLEM TO BE SOLVED: To provide a negative electrode material, or the like, for a non-aqueous electrolyte secondary battery in which the nonaqueous electrolyte secondary battery that has high initial charge/discharge efficiency, and is superior in the cycle performance can be obtained, while maintaining high battery capacity and a low volume expansion rate, after charging. SOLUTION: This is the negative material for the nonaqueous electrolyte secondary battery which contains an active material, composed of covered silicon oxide particles and silicon particles in which the surface of the silicon oxide particles is covered by a graphite coating, and a binder of 1 to 20 wt.%, and in which as for the graphite coating of the covered silicon oxide particles, the intensity ratio of a scattering peak in a raman spectrum analysis is 1.5 1330 1580 29 Si-DDMAS) measurement, a ratio S -84 /S -110 of a broad signal area having the -110 ppm vicinity as the center and a signal area of the -84 ppm vicinity is 0.5 -84 /S -110 COPYRIGHT: (C)2010,JPO&INPIT
