Hollow Carbon Nanospheres with a High Rate Capability for Lithium-Based Batteries

Higher spheres: Hollow carbon nanospheres are prepared from glucose through a facile, sustainable hydrothermal method. Their morphology provides fast electron and lithium ion transport, which is reflected in a superior rate capability (100 mAh g−1 at 50 C) and good cycle stability. Nevertheless, the...

Summary:Higher spheres: Hollow carbon nanospheres are prepared from glucose through a facile, sustainable hydrothermal method. Their morphology provides fast electron and lithium ion transport, which is reflected in a superior rate capability (100 mAh g−1 at 50 C) and good cycle stability. Nevertheless, these results provide direct evidence that not only lithium‐ion insertion/extraction to the carbon layers occurs, but also that a surface reaction contributes to the high rate performance.
