NEGATIVE-ELECTRODE ACTIVE MATERIAL, AND METHOD FOR PRODUCTION OF NEGATIVE-ELECTRODE ACTIVE MATERIAL |
摘要 |
A negative-electrode active material characterized by containing a silicon oxide represented by a general formula SiOx (0 aSibOc-m(OH)-n(H20), and a method for the production of a negative-electrode active material which includes a mixing step of mixing a silicon oxide that is represented by a general formula SiOy (0 < y < 2) and a metal oxide, and a heat treatment step of performing a heat treatment on the mixture that is obtained in the mixing step in a non-oxidizing atmosphere and in which the negative absolute value of the standard Gibbs energy of the oxidation reaction of the metal oxide at the heating temperature in the heat treatment step is smaller than the negative absolute value of the standard Gibbs energy of the oxidation reaction of Si at the heating temperature in the heat treatment step. |
