A one-step process to fabricate crystalline Li 4 Ti 5 O 12 (LTO) particles directly from solution using an atmospheric pressure plasma jet (APPJ) is reported. This process uses Ti and Li ions-containing salt solutions as the precursor, which is ultrasonically nebulized and then transported to the downstream of the APPJ using a carrier gas. With an extremely short contact time (<0.1 s) between the precursor droplets and the plasma jet, crystalline LTO can be fabricated in one step without additional rinse and postannealing steps. The LTO particle size can be effectively controlled using a preheater, the precursor solution composition and concentration, and the carrier gas flow rate. By properly adjusting the operating condition, particles of diameters from 100 nm to few lm with various morphologies can be obtained. When used as an electrode material, the resulting LTO powders fabricated under selected conditions show specific capacities over 100 mAh/g even at 50 C rate.

“…This result is further supported by the D Li values obtained from EIS, as shown in Figure b. D Li can be calculated according to eqs and (see the Supporting Information for symbol definitions): − On the basis of the calculation, the D Li values for LiCrTiO 4 nanowires and bulk LiCrTiO 4 were obtained. Obviously, D Li for the LiCrTiO 4 nanowires (1.02 × 10 –12 cm 2 s –1 ) is higher than that of bulk LiCrTiO 4 (9.67 × 10 –13 cm 2 s –1 ).…”

LiCrTiO4 is a lithium insertion material that is isostructural with Li4Ti5O12. Upon modification of its morphology, LiCrTiO4 nanowires exhibit a high charge capacity of 154.6 mA h g–1 at 100 mA g–1, and this value can be maintained at 121.0 mA h g–1 even at a high current density of 700 mA g–1. Furthermore, the cycling performance shows that LiCrTiO4 nanowires can also deliver a reversible capacity of 120.0 mA h g–1 with 95.6% capacity retention of the first cycle after 550 cycles. The excellent electrochemical properties were revalidated by cyclic voltammetry and electrochemical impedance spectroscopy measurements. The most interesting feature in this work is the relationship between the periodic variation of the (111) peak intensities and the migration of lithium ions during cycling. This proves that LiCrTiO4 nanowires are a zero-strain insertion material that can be a promising anode material for lithium ion batteries.

“…29 It has been reported that the electrochemical performance is influenced by different synthetic parameters, such as the starting materials (e.g., lithium salt), the calcination temperature, and the calcination time. 38,[74][75][76] Hong and co-workers 77 studied the influence of the starting materials and the annealing temperature on the rate performance and the capacity retention of LTO prepared under different conditions. They used Li 2 CO 3 and TiO 2 (either anatase or rutile), which were mixed with de-ionized water after adding 2 wt% of the ammonium salt of polycarboxylic acid as a dispersant.…”
