METHOD FOR PRODUCING SILICON OXIDE (SIOx 0<x<2), SILICON OXIDE PRODUCED BY PRODUCTION METHOD, NEGATIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY CONTAINING THE SILICON OXIDE, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY INCLUDING THE NEGATIVE ELECTRODE |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a novel method for producing silicon oxide (SiOx 0<x<2), especially a production method capable of producing silicon oxide suitable for a negative electrode active material of a nonaqueous electrolyte secondary battery.SOLUTION: High-quality silicon oxide (SiOx 0<x<2) suitable as a negative electrode active material of a nonaqueous electrolyte secondary battery can be produced by heating silicon dioxide (SiO) and silicon (Si) or carbon (C) under an atmosphere having an oxygen concentration of ≤0.5 vol% by using an arc furnace (electric arc furnace). |
