文摘
- •
CuCo2O4 microflowers assembled by porous nanosheets are synthesized.
- •
Porous structure and 2D morphology make them excellent in Li-ion/Li-O2 batteries.
- •
In Li-ion batteries, the capacity is ∼612 mA h g−1 after 500 cycles at 1 A g−1.
- •
In Li-O2 batteries, the life lasts 120 cycles by limiting capacity to 1000 mAh g−1.
