Ultrathin porous interconnected carbon nanosheets (UPICNs) were successfully prepared from sisal fibers via a combination of hydrothermal and activation processes. The structures of the UPICNs can be controlled by adjusting the weight ratio of alkali to sisal cellfibers. The UPICNs were made up of ultrathin (2 nm) interconnected carbon nanosheets with relatively high crystalline degree and an open meso-microporous surface area of 822.14 m2 g–1 at the optimal ratio of 2.5. The UPICNs electrode demonstrates excellent cycling performance, superior rate capability, and high reversible capacity when used as a lithium ion battery anode material. A reversible capacity of 685 mA h g–1 is maintained after 50 cycles at the current density of 0.05 A g–1. Even at a high current density of 2 A g–1, the reversible capacity was still retained at 279 mA h g–1 for over 1,000 cycles, rendering a nearly 100% corresponding coulombic efficiency.
