title: Graphene-Rich Wrapped Petal-Like Rutile TiO2tuned by Carbon Dots for High-Performance Sodium Storage.
abstract: Carbon dots inducing petal-like rutile TiO2wrapped by ultrathin graphene-rich layers are proposed to fabricate superior anodes for sodium-ion batteries, featuring high-rate capabilities and long-term cyclelife, benefiting from promoted electron transport and a shortened Na+diffusion length. High capacities of 144.4 mA h g-1(at 837.5 mA g-1) after 1100 cycles and 74.6 mA h g-1(at 3350 mA g-1) after 4000 cycles are delivered outstandingly.
