- •
A novel nanomaterial of flower-like porous carbon nanosheet powders (CNPs) is prepared.
- •
The CNPs exhibit almost double theoretical capacity of prototype graphite powders and stable cycling performance.
- •
A ‘path memory effect’ is put forward to explain its good cycle performance in detail.
