Method for manufacturing negative electrode active material for use in non-aqueous electrolyte secondary battery, negative electrode material for use in non-aqueous electrolyte secondary battery and non-aqueous electrolyte secondary battery |
摘要 |
The present invention provides a method for manufacturing a carbon-coated negative electrode active material for use in a non-aqueous electrolyte secondary battery, wherein a negative electrode active raw material including at least one of silicon oxide powder and silicon powder is coated with carbon by a catalytic CVD method.
The present invention also provides a negative electrode material for use in a non-aqueous electrolyte secondary battery and a non-aqueous electrolyte secondary battery using the negative electrode active material. As a result, there is provided a method for manufacturing a negative electrode active material for use in a non-aqueous electrolyte secondary battery in which high battery capacity given by the silicon-based active material is maintained and a volume expansion and a break in the active material are suppressed. |
