Abstract

A phasepure NaTi2PO43/reduced graphene oxide rGO nanocomposite was prepared using a microwaveassisted onepot method and subsequent heat treatment The wellcrystallized NaTi2PO43 nanoparticles 30–40 nm were uniformly precipitated on rGO templates through Ti–O–C bonds The chemical interactions between the NaTi2PO43 nanoparticles and rGO could immobilize the NaTi2PO43 nanoparticles on the rGO sheets which might be responsible for the excellent electrochemical performance of the nanocomposite The NaTi2PO43/rGO nanocomposite exhibited a specific capacity of 1286 mA·h·g–1 approaching the theoretical value at a 01 Crate with an excellent rate capability 729 capacity retention at 50 Crate and cycling performance only 45 capacity loss after 1000 cycles at a high rate of 10 C These properties were maintained even when the electrodes were prepared without the use of an additional conducting agent The excellent sodium storage properties of the NaTi2PO43/rGO nanocomposite could be attributed to the nanosized NaTi2PO43 particles which significantly reduced the transport lengths for Na+ ions and an intimate contact between the NaTi2PO43 particles and rGO due to chemical bonding
