Two-Dimensional Mesoporous Carbon Nanosheets as a High-Performance Anode Material for Lithium-Ion Batteries

Mesoporous carbon nanosheets (MCNSs) of 40 nm thickness and 10 μm width have been prepared. Dense mesopores with an average size of 9 nm were distributed in a disorderly manner throughout the nanosheets. Anodes made from MCNSs and applied in lithium-ion batteries delivered superior rate performances and stable cycle life (see figure).
