Lithium-Ion Batteries: Excimer Ultraviolet-Irradiated Carbon Nanofibers as Advanced Anodes for Long Cycle Life Lithium-Ion Batteries (Small 38/2016)

Carbon nanofibers (CNFs) bearing oxygen-containing functional groups and inhomogeneous nanopores are successfully prepared by excimer UV radiation, as presented by Y. Hu and co-workers on page 5269. 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.
