To fix these issues, Stanford’s researchers have turned to carbon nanospheres. Arranged in a honeycomb structure, the nanospheres form a protective layer over the lithium, remains stable during charging and discharging, and prevents damaging expansion of the lithium as the battery charges.

Yi Cui, a professor of Material Science and Engineering, says the carbon layer is the ideal level of stability for protecting the lithium layer, and withstanding its expansion.
