Hollow carbon nanospheres offer high rate capability as Li-ion electrode material

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.

Which can more economically be applied how?

Seems to be 4x superior to carbon at higher discharge rates (10C and above)

next article will be carbon nanorods coated in these spheres, then the following article will be some 3-dimensional structure coated in these spheres and so on :)
