Excimer Ultraviolet-Irradiated Carbon Nanofibers as Advanced Anodes for Long Cycle Life Lithium-Ion Batteries

Carbon nanofibers (CNFs) bearing oxygen-containing functional groups and inhomogeneous nanopores are successfully prepared by excimer UV radiation. The CNFs demonstrate potential for use as an anodic material in rechargeable Li-ion batteries. Their improved electrochemical performances are attributed to the chemically bonded solid–electrolyte interface films on the CNF surface. This approach is also applicable to other carbonaceous electrode materials. As a service to our authors and readers, this journal provides supporting information supplied by the authors.
