Nb2O5-Ge/GeO2 Nb2O5-Ge/GeO2 Manufacturing method of Nb2O5-Ge/GeO2 microcomposite for electrodes of secondary battery and electrode active material containing Nb2O5-Ge/GeO2 microcomposite prepared therefrom

摘要

The present invention relates to a secondary battery manufacturing method of the electrode Nb ₂ O ₅ -Ge / GeO ₂ and micro-composites for the secondary cell electrode active materials including the Nb ₂ O ₅ -Ge / GeO ₂ micro composites fabricated by this, and more specifically It has a shape suitable for minimizing the volume change due to lithium ion charging and discharging, and has a significantly small specific surface area, which is excellent in long-term stability, and at the same time, has a high capacity and high output characteristics. Nb ₂ O ₅ -Ge/GeO ₂ micro for secondary battery electrode It relates to a method for manufacturing a composite and an electrode active material for a secondary battery including the Nb ₂ O ₅ -Ge/GeO ₂ microcomposite prepared through the same.
