dc.description.abstract | Golden bristlegrass-like unique nanostructures comprising reduced graphene oxide (rGO) matrixed nanofibers entangled with bamboo-like N-doped carbon nanotubes (CNTs) containing CoSe(2)nanocrystals at each node (denoted as N-CNT/rGO/CoSe2NF) are designed as anodes for high-rate sodium-ion batteries (SIBs). Bamboo-like N-doped CNTs (N-CNTs) are successfully generated on the rGO matrixed nanofiber surface, between rGO sheets and mesopores, and interconnected chemically with homogeneously distributed rGO sheets. The defects in the N-CNTs formed by a simple etching process allow the complete phase conversion of Co into CoSe(2)through the efficient penetration of H2Se gas inside the CNT walls. The N-CNTs bridge the vertical defects for electron transfer in the rGO sheet layers and increase the distance between the rGO sheets during cycles. The discharge capacity of N-CNT/rGO/CoSe2NF after the 10 000th cycle at an extremely high current density of 10 A g(-1)is 264 mA h g(-1), and the capacity retention measured at the 100th cycle is 89%. N-CNT/rGO/CoSe2NF has final discharge capacities of 395, 363, 328, 304, 283, 263, 246, 223, 197, 171, and 151 mA h g(-1)at current densities of 1, 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 A g(-1), respectively. | - |
