“…The replacement of some oxygen with fluorine did not significantly affect the conductivity (Fergus, 2010). Furthermore, effective sintering to decrease grain boundary is important to improve total conductivity (Vidal et al, 2014).…”

The review presents an overview of the recent advances in inorganic solid lithium ion conductors, which are of great interest as solid electrolytes in all-solid-state lithium batteries. It is focused on two major categories: crystalline electrolytes and glass-based electrolytes. Important systems such as thio-LISICON Li 10 SnP 2 S 12 , garnet Li 7 La 3 Zr 2 O 12 , perovskite Li 3x La (2/3) x TiO 3 , NASICON Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 , and glass-ceramic xLi 2 S·(1 − x )P − 2 S 5 and their progress are described in great detail. Meanwhile, the review discusses different ongoing strategies on enhancing conductivity, optimizing electrolyte/electrode interface, and improving cell performance.

“…This result is slightly lower than that of other reports ( Table 2), indicating the higher Li-ion mobility of LLTO-F2 sample, which is beneficial to the high performance of solid electrolyte in a wide temperature range [23] . Table 2 summarizes the reported ion conductivities and activation energy of LLTO electrolyte prepared by different methods [4,16,[24][25][26][27] . It is clear that LiF assisted synthesis of LLTO sintered at 1100℃ could deliver an ion conductivity of 1.02×10 -4 S/cm at 25℃, which is comparable to that reported by many other groups, indicating the LLTO-F2 could prove a most advantageous in terms of electrochemical performance.…”

Perovskite-type solid-state electrolytes, Li0.35La0.55TiO3-xwt% LiF (LLTO-Fx, x = 0, 2, 4 and 6), were successfully synthesized through solid-state reaction method. The effects of LiF addition amount on LLTO crystal structure, morphologies and ionic conductivity have been investigated. All samples formed perovskite structure and the grain sizes were gradually increased with the increase of LiF content. Moreover, owing to the highest relative density (95.4%), LLTO-F2 electrolyte exhibited a highest total conductivity of 1.02×10-4 S/cm with a relative low activation energy of 0.26 eV, which is suitable for use in solid-state batteries. The cell Li/LLTO-F2/V2O5 exhibited a specific capacity about 270 mAh/g in the first few cycles and maintained 156 mAh/g after 100 cycles, demonstrating good cycling properties. Moreover, cells assembled with different cathodes, such as LiFePO4 and LiCoO2, also displayed excellent electrochemical performances. The results suggest that sintering additive (LiF) is very effective step towards ultimately achieve a safe solid-state lithium battery system.

Here, we provide an effective method to fabricate magnetic ZnO clay nanocomposite hydrogel via the photopolymerization. The inorganic components endow the hydrogel with high mechanical strength, while the organic copolymers exhibit good adsorption capacity and separation selectivity to La (III) ions. An optimized hydrogel has the maximum compressive stress of 316.60±15.83 kPa, which still exhibits 138.98±7.32 kPa compressive strength after swelling. The maximum adsorption capacity of La ion is 58.8 mg/g. The adsorption matches the pseudo-second-order kinetics model. La (III) ions can be effectively separated from the mixtures of La/Ni, La/Co, La/Cu, and La/Nd in a broad pH range (2.0 to 8.0). After six adsorption-desorption cycles, the hydrogel can maintain its adsorption capacity. This work not only provides a new approach to the synthesis of tough hydrogels under irradiation, but also opens up enormous opportunities to make full use of magnetic nanocomposite hydrogels in environmental fields.
