- •
Urchin-like CoO and Co3O4 hollow structures were produced for LIB anodes.
- •
CoO samples showed better cyclability and rate capability than Co3O4 samples.
- •
The best CoO sample showed a high capacity of about 850 mAh g−1 at 500 mA g−1.
- •
A high rate capability for the CoO sample was obtained.
