A team of Max Planck researchers from the Institutes for Solid State Research, Colloids and Interfaces, and Intelligent Systems has devised hollow carbon nanospheres from glucose that offer superior rate capability (100 mAh g−1 at 50 C) and good cycle stability as an electrode material in Li-ion batteries.

In a paper published in the journal ChemSusChem, they report that the morphology of the nanospheres, which are prepared via a facile, sustainable hydrothermal method, provides fast electron and lithium ion transport.
The results also show that not only lithium-ion insertion/extraction to the carbon layers occurs, but also that a surface reaction contributes to the high rate performance.
