One-Step Synthesis of Titanium Oxyhydroxy-Fluoride Rods and Research on the Electrochemical Performance for Lithium-ion Batteries and Sodium-ion Batteries


Titanium oxyhydroxy-fluoride, TiO0.9(OH)0.9F1.2 · 0.59H2O rods with a hexagonal tungsten bronze (HTB) structure, was synthesized via a facile one-step solvothermal method. The structure, morphology, and component of the products were characterized by X-ray powder diffraction (XRD), thermogravimetry (TG), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), inductively coupled plasma optical emission spectroscopy (ICP-OES), ion chromatograph, energy-dispersive X-ray (EDX) analyses, and so on. Different rod morphologies which ranged from nanoscale to submicron scale were simply obtained by adjusting reaction conditions. With one-dimension channels for Li/Na intercalation/de-intercalation, the electrochemical performance of titanium oxyhydroxy-fluoride for both lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) was also studied. Electrochemical tests revealed that, for LIBs, titanium oxyhydroxy-fluoride exhibited a stabilized reversible capacity of 200 mAh g−1 at 25 mA g−1 up to 120 cycles in the electrode potential range of 3.0–1.2 V and 140 mAh g−1 at 250 mA g−1 up to 500 cycles, especially; for SIBs, a high capacity of 100 mAh g−1 was maintained at 25 mA g−1 after 115 cycles in the potential range of 2.9–0.5 V.


Mixed-anion metal fluorides, which include metal oxyhydroxy-fluorides, metal hydroxy-fluorides, metal oxyfluorides, and so on, have become more and more attractive because of their characteristic structures and properties [112]. For example, FeOF1−x(OH)x · nH2O adopted the α-MnO2 structure [3], Ti0.75(OH)1.5F1.5 with the ReO3-type structure was studied as a UV absorber [8], and Ce1−xCaxO2−x−y/2Fy with the fluorite-type structure exhibited UV-shielding property [10]. In recent years, to extend the scope of existing electrode materials for lithium-ion batteries (LIBs) as well as sodium-ion batteries (SIBs) and make more progress in the development of clean energy, the use of mixed-anion metal fluorides was more and more popular [5, 1324]. Iron-based fluorides with the hexagonal tungsten bronze (HTB) structure were regarded as potential candidates for cathode material, and the research on their electrochemical performance has been ongoing for a period of time [5, 13]. Demourgues et al. reported that FeF2.2(OH)0.8−yOy/2y/2 with the HTB structure displayed better cyclability and reversible capacity than the precursor FeF2.2(OH)0.8 · (H2O)0.33 for LIBs [5]. Wang et al. reported that FeF3 · xH2O including the HTB structure FeF3 · 0.33H2O exhibited a discharge capacity of 101 mAh g−1 after 30 cycles in the potential range of 4.0–1.0 V at 0.1 C, which was quite high for SIBs [13]. Importantly, the electrochemical characteristics of the original samples proved the potentiality for further research.

In fact, another metal oxyhydroxy-fluoride with the HTB structure, titanium oxyhydroxy-fluoride has been reported by Demourgues et al. [2]. With the same one-dimension channels in structure and lighter Ti atomic weight, titanium oxyhydroxy-fluoride is also considered to be an attractive electrode material which supports Li/Na intercalation/de-intercalation into the host structure. The electrochemical reaction is supposed to benefit keeping certain electrode potential and studying how the HTB structure influences the electrochemical properties.

Herein, we demonstrate a facile one-step method to synthesize titanium oxyhydroxy-fluoride rods by introducing anions into titanium binary fluoride. The synthesis route started with the use of TiF4 powder (fluorine source), ethanol, and deionized water. The deionized water and ethanol volume using in reaction played significant roles in controlling the structure and morphology of the products, respectively. Structure features were studied by analyses of X-ray powder diffraction (XRD), thermogravimetry (TG), high-resolution TEM (HRTEM), and so on. Besides, the electrochemical properties of as-prepared half-cells were evaluated in detail for both LIBs and SIBs, which may help shed new light on the Li/Na intercalation/de-intercalation mechanism.



Titanium oxyhydroxy-fluoride was prepared as follows: TiF4 (Alfa Aesar 98 %) was firstly ground to fine powder in a glove box. After that, 1 g TiF4 was taken out and put in a 10 mL Teflon autoclave, then 1.20 mL deionized water and a certain volume of ethanol were put in the autoclave sequentially. Operation in this step should be quick to avoid earlier hydrolysis of TiF4. The autoclave was heated to 150 °C and kept for 48 h. The precipitate was centrifuged, washed with deionized water over three times, and kept in a vacuum oven at 60 °C for 12 h to get the final products. The ethanol volume used can be described as follows: 1.88 mL ethanol for long titanium oxyhydroxy-fluoride rods, 0.47 mL ethanol for short titanium oxyhydroxy-fluoride rods, and 0.94 mL ethanol for titanium oxyhydroxy-fluoride with the morphology of hexagonal rods. In this article, the sample used for TG and galvanostatic charge–discharge tests is long TiO0.9(OH)0.9F1.2 · 0.59H2O rods.


The crystal structure features of as-prepared materials were characterized by X-ray powder diffraction on a Philips X’pert X-ray diffractometer using Cu Kα1 radiation at room temperature. The morphology images of as-prepared materials were taken on a JEOL JSM-6700F scanning electron microscope. The transmission electron microscopy (TEM) and HRTEM images were taken on a JEOL-2010 transmission electron microscope. The thermostabilization of as-prepared materials was characterized by thermogravimetry analysis on a DTG-60H thermogravimetry analyzer which worked under nitrogen atmosphere at a heating rate of 10 °C/min from room temperature to 700 °C. The Ti content was characterized by inductively coupled plasma optical emission spectroscopy (ICP-OES) using Atomscan Advantage. The F content was characterized by ion chromatograph (ICS-3000). The [F]/[Ti] molar ratio was further confirmed by energy-dispersive X-ray (EDX) analysis recorded on the JEOL-2010 transmission electron microscope.

Electrochemical Measurement

The electrochemical behavior of all the aforementioned products was tested for LIBs and SIBs by the galvanostatic charge–discharge method at room temperature. For LIBs, the half-cells were composed of the as-prepared product as working electrode, Li metal as counter and reference electrode, and the 1 M LiPF6 ethylene carbonate/dimethylcarbonate (volume ratio 1:1) solution as electrolyte, which were assembled as coin cells (2016 R-type). The composition of the working electrode was active material (70 %), Super P-carbon black (20 %), and sodium carboxymethyl cellulose binder (10 %); 70, 20 and 10 % were the weight percentage. The above mixture was ground in water and then homogeneously pasted on a Cu slice; after that, the Cu slice was dried in a vacuum oven which was heated to 80 °C for 12 h. The assembling was operated in a glove box. The glove box was full of argon, in which oxygen and H2O were kept under 0.1 ppm. For SIBs, the preparation of Cu slice with the active material was in the same procedure which has been introduced above. The differences were we used Na metal as counter and reference electrode, fiberglass instead of polypropylene as separator, and 1 M NaClO4 in propylene carbonate as electrolyte. Tests of electrochemical performance were taken on a Neware-BTS-TC53 instrument at required current densities and in the appropriate electrode potential window.

Results and Discussion

The XRD pattern of titanium oxyhydroxy-fluoride is shown in Fig. 1. All of the diffraction peaks are indexed by a hexagonal lattice with the lattice parameters a = 7.3636 Å, c = 7.5186 Å, and the space group P63/mmc, which are consistent with the HTB-Ti0.75O0.25(OH)1.3F1.2 reported by Demourgues et al. [2]. It is confirmed that titanium oxyhydroxy-fluoride had the HTB structure without observed impurity. The atom mole ratio [F]/[Ti] is 1.2 which is confirmed by analyzing the results of ion chromatograph, ICP-OES, and EDX. The HTB structural frame shown as inlet is viewed down the [001] direction; the one-dimension channels in the structure are expected to benefit Li and Na intercalation/de-intercalation. It is noteworthy that, the XRD patterns of titanium oxyhydroxy-fluoride with different morphologies are identical.

TG curves of titanium oxyhydroxy-fluoride are shown in Fig. 2. There are two weight losses in the thermal decomposition of titanium oxyhydroxy-fluoride from room temperature to 700 °C. Firstly, a weight loss of approx 9 % occurs and ends at 370 °C. It is considered that the first weight loss is related to the water absorbed on titanium oxyhydroxy-fluoride powders. Secondly, a bulky weight loss of 41 % occurring at 370–520 °C is considered to be due to the thermal decomposition of titanium oxyhydroxy-fluoride. In this period, OH and F constituents depart in the form of H2O and TiF4 (g), respectively. It can also be considered that the sequential H2O departure and TiF4 loss correspond to the two peaks of the first derivative, for the fact under certain temperature only H2O departure is observed in the thermal treatment of FeF2.2(OH)0.8 · (H2O)0.33 which is reported by Demourgues et al. [5]. The thermal decomposition of titanium oxyhydroxy-fluoride finally leads to the formation of TiO2 when the temperature reaches 520 °C. The bulky weight loss and decomposition temperature of titanium oxyhydroxy-fluoride are similar to TiOF2 which has been studied recently [16, 25]. After taking into consideration of the analyses of the TG curves and the mole ratio [F]/[Ti], the formula for titanium oxyhydroxy-fluoride should be proposed as: TiO0.9(OH)0.9F1.2 · 0.59H2O, which is analogous to the one presented by Demourgues et al. [2].

The morphology and structure features of titanium oxyhydroxy-fluoride, TiO0.9(OH)0.9F1.2 · 0.59H2O particles are also investigated through the analyses of scanning electron microscopy (SEM), TEM, HRTEM images and the corresponding FFT image. The size of long TiO0.9(OH)0.9F1.2 · 0.59H2O rods (Fig. 3a) is approx 2 μm long and 100–500 nm in diameter; the typical long rod with the regular shape is shown in Fig. 3d. For short TiO0.9(OH)0.9F1.2 · 0.59H2O rods (Fig. 3b), the length ranges from 700 to 1300 nm and the diameter ranges from 250 to 400 nm. All the TiO0.9(OH)0.9F1.2 · 0.59H2O rods with different morphologies are synthesized under the same condition with the only difference of the ethanol volume. Actually, if only the volume of deionized water is changed (from 1.20 mL to 0.15 mL), another compound hexagonal TiOF2 is synthesized. The sole difference between the synthesis of TiO0.9(OH)0.9F1.2 · 0.59H2O and hexagonal TiOF2 ,i.e., the volume of deionized water indicates that during the synthesis of TiO0.9(OH)0.9F1.2 · 0.59H2O, more hydrolysis reactions of TiF4 occur and Ti4+ binds the generated hydroxy to form the final product with the HTB structure. In other words, the hydroxy groups are considered to be very important for the firm HTB structure. It can also be concluded that the deionized water volume of reaction decides the structure of the products while the ethanol volume plays a significant role in affecting the morphology. The 0.38-nm interfringe spacing in Fig. 3e corresponds to the (002) lattice plane of TiO0.9(OH)0.9F1.2 · 0.59H2O. The vertical (120) and (002) lattice plane in Fig. 3e are also confirmed by the FFT image (Fig. 3f).

To investigate the electrochemical properties of titanium oxyhydroxy-fluoride TiO0.9(OH)0.9F1.2 · 0.59H2O, both LIBs and SIBs are performed by using galvanostatic charge/discharge method. The results are shown in Figs. 4 and 5. For LIBs, during the first cycle, the discharge plateau appears at 2.4 V and last until the electrode potential reaches 1.2 V, and the only one plateau suggests that there is only one lithiated TiO0.9(OH)0.9F1.2 · 0.59H2O phase ,i.e., no other phase transition of TiO0.9(OH)0.9F1.2 · 0.59H2O is observed during the lithiation of TiO0.9(OH)0.9F1.2 · 0.59H2O. The potential range where Li intercalation/de-intercalation occurs in is 3.0–1.2 V, which can also be illustrated by Fig. 4b. The specific capacity of the first discharge and the first charge is 270 mAh g−1 and 200 mAh g−1, while the specific capacities of the following cycles, whether of charge or of discharge, are approx 200 mAh g−1. TiO0.9(OH)0.9F1.2 · 0.59H2O exhibits stabilized 200, 170, 150, and 140 mAh g−1 at 25, 50, 125, and 250 mA g−1, respectively, in the electrode potential range of 3–1.2 V without observed fading for 120–500 cycles (Fig. 4c and d), which is pretty satisfying and illustrates the highly reversible nature. Besides, after cycling at 25 mA g−1 again, the specific capacity of TiO0.9(OH)0.9F1.2 · 0.59H2O is recovered (Fig. 4d). It is noteworthy that the stabilized 200 mAh g−1 capacity of TiO0.9(OH)0.9F1.2 · 0.59H2O is quite large, compared with that of Li4Ti5O12 (theoretical capacity 170 mAh g−1). The good rate capacity and cycling stability are connected with the one-dimension channels in the HTB structure and the morphology of homogeneous rods.

For SIBs, in the first cycle the discharge plateau appears at about 1.6 V and ends at 0.5 V which is higher than TiO2 [26], and the potential of Na intercalation/de-intercalation is above 0.5 V which is shown in Fig. 5b. The specific capacity of the first discharge is 233 mAh g−1 (Fig. 5a), and after the first discharge, the specific capacity gradually decreases from 150 mAh g−1 (the second discharge) to 111 mAh g−1 (the 50th discharge), but it is still above 100 mAh g−1 after 115 cycles (Fig. 5d). The electrochemical performance of another product obtained under the similar reaction condition, hexagonal TiOF2, is shown in Fig. 5c, the details of this work is introduced in another article which is submitting. The capacities of the former 20 cycles of the TiO0.9(OH)0.9F1.2 · 0.59H2O half-cell in the potential range of 2.9–0.5 V are higher than hexagonal TiOF2 even the potential ranges from 3.0 to 0.05 V, which is considered to be facilitated by the HTB structure. The TiO0.9(OH)0.9F1.2 · 0.59H2O half-cell cycled at 125 mA g−1 stabilizes at a specific capacity of 100 mAh g−1 and it is considered to be due to the incomplete Na intercalation/de-intercalation (Fig. 5d). The rate capacity of TiO0.9(OH)0.9F1.2 · 0.59H2O for SIBs is shown in Fig. 5e, TiO0.9(OH)0.9F1.2 · 0.59H2O exhibits a capacity of 160, 130, 120, and 100 mAh g−1 cycled at 25, 50, 75, and 125 mA g−1, respectively. 76 % capacity of the second discharge ,i.e., 130 mAh g−1 is retained after cycling at 25 mA g−1 again without observed fading for another 35 cycles. Compared with LIBs, the electrochemical performance of TiO0.9(OH)0.9F1.2 · 0.59H2O for SIBs is restricted, whether the capacities or the cycling stability, which may be related to the different ion sizes and diffusion rates of Li and Na ions.


In summary, titanium oxyhydroxy-fluoride TiO0.9(OH)0.9F1.2 · 0.59H2O with the HTB structure is synthesized by a facile one-step method. The purity of the products is confirmed, and products with various morphologies are obtained by adjusting the volume of ethanol used in the synthesis process. The electrochemical performance of TiO0.9(OH)0.9F1.2 · 0.59H2O is also studied to investigate Li/Na intercalation/de-intercalation in the HTB structure. For LIBs, TiO0.9(OH)0.9F1.2 · 0.59H2O delivered a stabilized capacity of 200 mAh g−1 under a current density of 25 mA g−1 in the former 120 cycles; the capacities of 150 mAh g−1 and 140 mAh g−1 are also exhibited without observed fading after 500 cycles at 125 mA g−1 and 250 mA g−1, respectively, which demonstrated the highly reversible cycling stability of TiO0.9(OH)0.9F1.2 · 0.59H2O. For SIBs, TiO0.9(OH)0.9F1.2 · 0.59H2O exhibits capacities above 130 mAh g−1 in the former 20 cycles and capacities above 100 mAh g−1 in the former 115 cycles, which is quite large and it is potential for the further improvement of TiO0.9(OH)0.9F1.2 · 0.59H2O. We believe TiO0.9(OH)0.9F1.2 · 0.59H2O is potential as an electrode material, and the electrochemical properties will be improved by further research such as nanocomposite and carbon-coated process.
