Abstract

A perfluorinated alkyl chain grafted to carbon nanotubes is employed in the lithium–oxygen (Li–O2) cell. We demonstrate a highly localized Li–O2 electrochemical reaction in close proximity to the perfluorinated moiety owing to its high O2 affinity. This hydrophobic modification can provide an enhancement in capacity for a very thin microbattery system.
