文摘
- •
Porous carbon (PC) is fabricated by dual-activation process of PVdF-HFP.
- •
As-synthesized PC has an extremely large surface area over 2000 m2 g−1.
- •
The PC was composited with sulfur (PC/S) via melt diffusion process.
- •
The PC/S electrodes demonstrate over 730 mA h g−1 of capacity after 100 cycles.
