Description
Technical Field
The invention relates to the technical field of material detection, in particular to a detection method of a solid electrolyte lithium lanthanum zirconium oxygen LLZO material.
Background
The solid electrolyte materials that are currently mainstream can be classified into three major categories, oxide, sulfide, and polymer. Among them, oxides are widely noticed because they are stable to air and have high ionic conductivity.
The garnet-type oxide solid electrolyte material Lithium Lanthanum Zirconium Oxygen (LLZO) is considered to be one of the most desirable solid electrolyte materials for solid batteries because of its excellent ionic conductivity and readily available raw materials. Since the garnet-type LLZO is divided into two phase structures of cubic phase and tetragonal phase, the ionic conductivity of the cubic phase can reach 0.1 to 1ms/m, but the LLZO ionic conductivity of the tetragonal phase is extremely low. Therefore, in practical research applications and production processes, the cubic phase of LLZO is mainly used.
In the LLZO sintering process, the phase forming condition is harsh because the material composition is complex. In the actual sintering process, tetragonal mixed phases also appear, and the influence on the material performance is large. Thus, phase detection of LLZO becomes necessary.
The detection method commonly adopted for the phase detection of LLZO at present is an X-ray diffraction (XRD) method, and the phase of LLZO is tested by X-ray diffraction to analyze the composition of the heterogeneous phase in the LLZO.
However, using XRD as a method for detecting the composition of LLZO phase has the following two disadvantages:
1. the sensitivity of phase detection by XRD is 1%, and when the content of the impure phase is lower than 1%, the existence of the impure phase cannot be detected by XRD;
2. when the phase analysis is performed by XRD, only the impurity phase can be qualitatively analyzed, and the specific composition of the cubic phase and the tetragonal phase in LLZO cannot be quantitatively analyzed.

Detailed Description
The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.
The embodiment of the invention provides a detection method of a solid electrolyte Lithium Lanthanum Zirconium Oxide (LLZO) material, which mainly comprises the following steps as shown in figure 1:
preferably, the first mass is in the range of 0.1g to 10 g; the second mass is in the range of 100-500 g.
More preferably, the first mass and the second mass are in the above range in a ratio of 1: 20.
preferably, the mixed acid solution is specifically: concentrating the nitric acid HNO according to the volume ratio3Concentrated hydrochloric acid HCl: mixed acid solution prepared with HF 4:12: 1.
And 150, determining whether the four-square-phase impurity phase exists in the LLZO powder material to be detected or not according to the ratio of m1 to m 2.
Wherein when the ratio of m1 to m2 is equal to Li in the first mass of cubic phase LLZO+/H+Exchanged Li+When the quantity is in the ratio of m2, determining that the LLZO in the LLZO powder material to be detected is cubic phase and no tetragonal phase impurity phase exists; when the ratio of m1 to m2 is less than Li in the first mass of cubic phase LLZO+/H+Exchanged Li+And when the quantity is in the ratio of m2, determining that the LLZO in the LLZO powder material to be detected has a tetragonal phase.
The method utilizes Li in cubic phase LLZO and tetragonal phase LLZO+/H+The ion exchange degree of (a) is different, so as to realize the detection.
Specifically, the garnet-type solid electrolyte material LLZO has two phase structures — a cubic phase and a tetragonal phase. The space group of the tetragonal phase is No.142I41/acd, and the unit cell parameter is
The space group of the cubic phase is No.230Ia3d, and the unit cell parameter is
The frameworks of these two crystal structures are identical, 8-coordinated [ LaO8]Hexahedron and 6-coordinated [ ZrO6]Octahedral form of the frame. The difference between the two is that the Li + occupies a different space in the crystal structure.
In the structure of the tetragonal phase, lithium ions are distributed at three positions, namely tetrahedral voids 8a (Li1), regular octahedral voids 16f (Li2) and octahedral voids 32g (Li3), and the occupancy is 1. In the cubic phase structure, lithium ions are distributed at two locations, tetrahedral voids (24d) and eccentric octahedral voids (96h), respectively. Wherein the Li1 occupancy rate of 24d in the [ LiO4] tetrahedral position is 0.94, and the Li2 occupancy rate of 96h in the [ LiO6] octahedral position is 0.349.
Cubic phase LLZO is essentially a lithium ion disordered metastable phase, while tetragonal phase LLZO is stable. Due to Li in cubic phase LLZO+And H+There is a strong ion exchange reaction, and at room temperature, Li occurs between cubic phase LLZO and water in air+And H+The exchange of (2). Due to the tetragonal phase of LLZO, Li+All occupy 1, so Li+/H+Is 0. This difference occurs mainly due to the fact that the crystal structure of the cubic phase differs from that of the tetragonal phase, resulting in a different degree of ion exchange reaction of Li +/H +.
In cubic phase LLZO, the Li1 sites account for the total Li+36% of the number, the Li2 site accounting for the total Li+25% of the number, the Li3 site accounting for the total Li+39% of the number. According to Li1, Li2, Li3 different sites Li+The extent of exchange of/H + is different in the occurrence of Li+/H+At the exchange, Li2 site and Li3 site+Will be completely replaced by H +, i.e. there will be 64% Li in cubic phase LLZO+Is replaced by H+. While tetragonal phase LLZO is structurally stable, Li+/H+Is 0.
Therefore, in the above step, the measured content m1 corresponds to Li2 sites and Li3 sites of the cubic phase LLZO existing in the first mass of the LLZO powder material to be measured+The amount of (c). I.e. Li in the first mass of cubic phase LLZO+/H+Exchanged Li+Amount of the compound (A).
And in the process of digesting in the mixed acid solution, all Li in the LLZO powder material to be measured with the first mass is converted into Li+I.e. the measured content m2, corresponds to the Li of all the LLZO in the first LLZO powder material to be measured+The amount of (c).
If only cubic phase LLZO exists in the LLZO powder material to be measured, the content m1 corresponds to 64% of Li+The content m2 is 100% of Li+。
If the LLZO powder material to be measured has not only cubic phase LLZO but also tetragonal phase LLZO, the content m1 is less than 64% Li+The content m2 is still 100% Li+。
Therefore, in the judgment of the step 150, it can be considered that if m1/m2 is 64%, it is determined that all the LLZO in the LLZO powder material to be measured is cubic, and no tetragonal phase impurity phase exists; and if m1/m2 is less than 64%, determining that the LLZO in the LLZO powder material to be detected has a tetragonal phase.
Further, after determining whether the tetragonal phase impurity phase exists in the LLZO powder material to be detected, the detection method of the invention also comprises the following steps of quantifying the tetragonal phase impurity phase:
when the existence of the tetragonal phase hetero phase in the LLZO powder material to be detected is determined, calculating the occupation ratio of the tetragonal phase of the LLZO powder material to be detected according to [ (0.64 x m2-m1)/(0.64 x m2) ] 100%. The allowable error fluctuation range is 64% + -0.5%.
This is because 64%. times.m 2 is Li in the cubic phase LLZO+/H+Exchanged Li+Amount, but because of the presence of tetragonal phase LLZO, Li is actually exchanged+The amount of Li in the part is small (0.64 Xm 2-m1)+The amount is in tetragonal phase LLZO.
Therefore, the proportion of tetragonal phase LLZO is [ (0.64 xm 2-m1)/(0.64 xm 2) ] 100%, and the remainder is the proportion of cubic phase LLZO.
In order to better understand the technical scheme of the invention, the following specific examples are illustrated.
Example 1
The LLZO powder A to be tested was ground and sieved through a 200 mesh screen.
0.2g of the sieved LLZO powder was soaked in 150g of deionized water. After soaking for 24 hours, the powder was filtered out using filter paper, the filtrate was taken and tested for Li in the filtrate using ICP+M1, m1 is 49 mg/L.

Testing Li in digestion solution using ICP+M2, and m2 is 77 mg/L.
Comparing the Li + content of m1 with m2, m1/m2 ≈ 64%, the tested LLZO materials are considered cubic phase LLZO without tetragonal phase LLZO impurity phase.
Example 2

0.2g of the sieved LLZO powder is put into a container filled with concentrated nitric acid (HNO)3Concentrated hydrochloric acid HCl: and (3) digesting the LLZO powder by microwaves in a mixed acid solution prepared by the ratio of HF to 12: 1. Testing Li in digestion solution using ICP+M2, and m2 is 77 mg/L.
Comparing the Li + content of m1 with m2, with m1/m2 being 38.96% < 64%, it is assumed that a portion of the tetragonal phase LLZO impurity phase is present in the tested LLZO material, and the amount of tetragonal phase impurities is 39.1234%%, by calculation.

0.1g of the sieved LLZO powder is put into a container filled with concentrated nitric acid (HNO)3Concentrated hydrochloric acid HCl: and (3) digesting the LLZO powder by microwaves in a mixed acid solution prepared by the ratio of HF to 12: 1. Testing Li in digestion solution using ICP+M2, and m2 is 39 mg/L.
Comparing the Li + content of m1 with that of m2, m1/m2 ≈ 56.41% < 64%, considering that part of the tetragonal phase LLZO impurity phase exists in the tested LLZO material, according to calculation, the content of tetragonal phase impurities is 11.8590%
