- •
A facile template-assisted method has been proposed to prepare hollow carbon shell.
- •
Ultrathin hollow carbon shell was unprecedentedly prepared from petroleum asphalt.
- •
The ultrathin carbon shell shortens the distance of ion diffusion to less than 2.5 nm.
- •
Hollow carbon shell shows a capacity of 334 mA h g−1 after 1000 cycles at 1 A g−1.
