Title:
NEGATIVE ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS SECONDARY BATTERY, AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/014381
Kind Code:
A1
Abstract:
A negative electrode active material for a non-aqueous secondary battery, which comprises a composite powder complexed by milling a silicon-oxide-based powder containing silicon oxide and an iron-based powder containing iron, and which is characterized in that the composite powder comprises silicon oxide derived from the silicon-oxide-based powder and iron derived from the iron-based powder and/or an iron compound containing iron derived from the iron-based powder.
This negative electrode active material for a non-aqueous secondary battery can have both an initial charge-discharge efficiency of a non-aqueous secondary battery and cycle properties in spite of a matter the negative electrode active material contains silicon oxide.
