Twisted carbonaceous nanoribbons as high-performance anode material for lithium-ion batteries

The high demands on lithium-ion batteries (LIBs) have increased concern about novel carbon nanomaterials with high capacity and cycling stability. Herein, twisted carbonaceous nanoribbons with high BET specific surface area of 1413 m2 g−1 were successfully synthesized using twisted 4, 4′-biphenylene bridged polybissilsesquioxane tubular nanoribbons as the starting material. Electrochemical measurement showed that the carbonaceous nanoribbon electrode not only delivered a high specific capacity of 921.1 mAh g−1 after 250 cycles at a current density of 0.1 A g−1, but also exhibited superior cycling stability and excellent rating capability. The work presents a facile way to design and fabricate good anode candidate for LIBs.
