英文摘要: Abstract(#br)Low capacity and poor cycle stability are two typical drawbacks of Na 2 Ti 3 O 7 when applied to the sodium-ion batteries as electrode materials. Here, we successfully synthesized Na 2 Ti 3 O 7 by a mild process in chloride/ethylene glycol-based deep eutectic solvent. The prepared Na 2 Ti 3 O 7 overcomes the above drawbacks of Na 2 Ti 3 O 7 which was synthesized by conventional methods. Our synthesized Na 2 Ti 3 O 7 can deliver discharge capacities of 127 mAh g −1 after 50 cycles and 72 mAh g −1 after 2000 cycles at current density of 1C and 5C, respectively. This cheap and environmentally friendly Na 2 Ti 3 O 7 exhibits excellent rate performance and cycling stability. In addition, we also further investigate the sodium storage mechanism of this product, the results show...
