A High Performance Lithium-Ion Battery Anode Based on Flexible Free-standing VACNTs on Reduced Activated Graphene Oxide Paper

A flexible, high-performance lithium-ion battery electrode was fabricated by controllable growth of vertically aligned carbon nanotubes (VACNTs) on a porous, free-standing reduced activated graphene oxide (r-aGO) paper substrate via plasma-enhanced chemical vapor deposition. The electrochemical properties of the resulting flexible device were evaluated. Superior cyclic stability, making them ideal for high-performance lithium-ion battery anodes. The fabricated ۳D flexible anode demonstrated an impressive initial discharge capacity of ۱۳۹۰ mAhg-۱, followed by a stable reversible capacity of ۴۵۱ mAhg-۱ after ۱۰۰ cycles at a current density of ۱۵۰ mAg-۱, with nearly ۱۰۰% coulombic efficiency. This exceptional performance surpasses that of most other carbon-based materials.
