The high temperature sintered ceramic pellets of solid electrolyte Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP), obtained in the absence of any sintering aids, should contain a large amount of interparticle gaps, which is one of the main bottlenecks in developing LATP-based all-solid-state Li-metal batteries. In this study, a facile solution (LiCl in ethanol) immersion method is adopted to soak the already 900℃-sintered LATP ceramic pellets, and the resulting series of LATP-xLiCl (x denotes the weight fraction of LiCl, 0.0 ≤ x ≤ 3.7) are assayed to address the high-performance mechanism of lithium-graphite (Li-C) symmetric cells. At the optimal x value of 2.3, the grain-boundary resistance of the ceramic pellet can be significantly reduced from 1772 to 28 Ω·cm² at room temperature, which endows the Li-C symmetrical cells of LATP-2.3LiCl with a high critical current density of 3.00 mA cm² at 60°C. Especially, the enhanced ionic conductivity of LATP-2.3LiCl (4.7×10 −4 S cm −1 , at 20℃; 1.1×10 −3 S cm −1 , at 60℃) indicates an effective strategy of utilizing capillary force to densify LATP-based ceramic pellets for potential application purposes.

Solid-state poly(ethylene oxide) (PEO) electrolyte exhibits a low ionic conductivity at ambient conditions, and large interfacial resistance between PEO and electrodes obstructs its applications in lithium metal batteries. Heterogeneous solid electrolytes (HSEs) are an alluring solution for the exploitation of PEO. Herein, PEO/poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)/micron-sized Li 1.4 Al 0.4 Ti 1.6 (PO 4 ) 3 (LATP) heterogeneous solid electrolytes are originally prepared to decrease the crystallinity of PEO and interfacial resistance between HSEs and electrodes. Heterogeneous solid electrolyte composed of PEO/PVDF-HFP/5% micron-sized LATP (PPL-5) exhibits superior electrochemical properties in ionic conductivity (3.01 × 10 −5 S cm −1 ), lithium transference number (0.55) at 30 °C, and a broad potential window (5.31 V). Li/PPL-5/Li symmetric cell displays a relatively stable potential response during 800 h cycling, authenticating long-term compatibility between the as-prepared electrolyte and lithium metal. LiFePO 4 (LFP) is used as a cathode to test the chemical and electrochemical stability of PPL-5. The discharge capacity of LFP/PPL-5/Li coin cell maintains 97.9 mAh g −1 at 0.8 C after 500 cycles with capacity retention of 86.7%. Such excellent performance of PPL-5 can be ascribed to the reduction of crystallinity of PEO and the improvement of the interfacial contact between electrolyte and electrodes, when PVDF-HFP and micron-sized LATP are simultaneously incorporated with PEO electrolyte.

In this paper, a NASICON-type Li1.3Al0.3Ti1.7(PO4)3 (LATP)/Li1.3Al0.3Ge1.7(PO4)3 (LAGP) bi-layer structured solid state electrolyte was successfully prepared via a simple dry pressing and post-calcination method. By adjusting the sintering temperature for LAGP starting materials, a dense and smooth LATP/LAGP double-layer solid state electrolyte with no defects was obtained. This electrolyte sample exhibits a high electrical conductivity of 3.4 × 10−4 S cm−1 and a negligible electronic conductivity of 9.6 × 10−9 S cm−1 at room temperature. In addition, the LATP/LAGP electrolyte also shows an excellent stability in air as well as chemical stability against Li. Moreover, an assembled LiFePO4/LATP–LAGP/Li coin-type battery employing LATP/LAGP as the solid state electrolyte can be suitably charged and discharged at a current rate of 0.1C at room temperature, and its low charge–discharge capacities are mainly attributed to the high electrolyte/electrode interfacial resistance of the cell. These results suggest that the LATP/LAGP bi-layer electrolyte can be an alternative electrolyte for all-solid-state lithium-ion batteries.

Achieving high metal leaching efficiency via regulation strategy is essential for minimizing raw material waste and reducing waste generation in hydrometallurgy. However, conventional approaches of tuning temperature and time frequently result in increased equipment corrosion and increased industrial costs. Therefore, recycling waste solid-state battery relies on the development of new tuning strategies. Here, a new strategy is developed to tune the leaching efficiency of metals by amino acid-based low-melting mixture solvents from lithium aluminum titanium phosphate Li 1.3 Al 0.3 Ti 1.7 P 3 O 12 (LATP) in all-solid-state lithium-ion batteries. This novel strategy demonstrates a more pronounced metal leaching efficiency, resulting in an increase in the highest Li leaching efficiency from 48.0% to 78.2%. In comparison, tunability by solvent types, temperature, and time on Li efficiency is less efficient, with Li efficiency only varying from 44.9% to 52.3%, 37.7% to 51.0%, and 36.8% to 56.3%, respectively. Graphical A new and sustainable strategy is developed to tune the recycling of solid electrolyte LATP by adjusting ternary components in the biodegradable and biocompatible amino acid-based low-melting mixture solvents, achieving a significant increase in Li leaching efficiency from 48.0% to 78.2%, indicating a 1.6-fold enhancement.

Surface functionalization is an effective strategy to reduce the chemical reactivity between a Li1.3Al0.3Ti1.7(PO4)3 (LATP) electrolyte and Li metal anode and optimize the interfacial contact of different components. Herein, sodium itaconate (SI) is introduced to modify the surfaces of LATP particles (LATP@SI) via a self-polymerizing process, and a composite solid electrolyte (CSE) composed of poly(ethylene oxide) (PEO) and LATP@SI is fabricated. Benefiting from the protection of the SI nanolayer, LATP demonstrates chemical compatibility with the Li metal anode, while the reduced surface energy renders a good dispersion of LATP in PEO. Furthermore, abundant carboxyl groups in SI can offer a bridge between LATP and PEO to accelerate Li+ transmission. As a result, the as-prepared PEO-LATP@SI-6 CSE exhibits a high ionic conductivity of 1.15 × 10–4 S cm–1 at 30 °C and 1.20 × 10–3 S cm–1 at 60 °C, a wide electrochemical stable window beyond 5.0 V, an improved Li+ transference number of 0.41, and an optimized lithium compatibility over 1200 h with Li dendrite free. The as-assembled Li||PEO-LATP@SI-6 CSE||LiFePO4 full battery delivers a high reversible capacity of 155 mAh g–1 and an outstanding capacity retention of 89% after 200 cycles. The Li||LiFePO4 pouch cell also successfully runs 50 cycles with a terminal discharge capacity of 116.6 mA h g–1. This study opens a new avenue to protect LATP. The developed surface functionalization technique promises a facile and efficient method for interfacial engineering to accelerate the practical application of LATP in solid-state lithium batteries.

LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811) is considered as a promising cathode for high-energy-density solid-sate Li metal battery for its high theoretical capacity. However, the high oxidizability and structural instability during charge limit its practical applications. In this work, 1% (in mass) of nanosized Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) was coated on NCM811 to enhance its electrochemical stability with a ceramic/polymer composite electrolyte. A robust, ultrathin (11 μm) composite electrolyte film was prepared by combining poly(vinylidene fluoride) (PVDF) with polyethylene oxide (PEO)-Li 6.5 La 3 Zr 1.5 Ta 0.5 O 12 (LLZTO). An in-situ polymerization process was used to enhance the interface between the PVDF/PEO-LLZTO (PPL) composite electrolyte and the LATP-coated NCM811 (LATP-NCM811). Coin-type Li|LATP-NCM811 cell with the PPL electrolyte exhibits stable cycling with an 81% capacity retention after 100 cycles at 0.5 C. Pouch-type cell was also fabricated, which can be stably cycled for 70 cycles at 0.5 C/1.0 C (80% retention), and withstand abuse tests of bending, cutting and nail penetration. This work provides an applicable method to fabricate solid-state Li metal batteries with high performance.

The rapid increase in the commercialization of electric vehicles and portable electronics has markedly raised the demand for lithium resources. Extracting lithium from brine has become a critical pathway to address future lithium production challenges. However, the lithium extraction efficiency of conventional technologies is limited by the low levels of Li + and the high Mg 2+ /Li + ratio present in brine. A method involving one-step electrolysis with a solid-state electrolyte has been introduced for the direct and efficient extraction of metallic lithium. Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) is considered a highly promising selective membrane for large-scale lithium extraction from brine sources due to its low cost, excellent stability, and high ionic conductivity. Herein, LATP electrolytes were synthesized through the optimization of solid-state reaction conditions. The resulting LATP pellets exhibited a high relative density of 98.29 % and an impressive ionic conductivity of 3.88 × 10 −4 S cm −1 . The lithium extraction device utilizing LATP as a selective membrane achieved a remarkable current efficiency of 97.4 % and a high lithium production rate of 40.4 μg h −1 cm −2 . After lithium extraction process, the LATP pellets retained the ionic conductivity of 2.69 × 10 −4 S cm −1 and preserved the sodium super ion conductors (NASICON) crystal structure. This study presents an efficient Li + selective membrane for extracting lithium directly from natural brine.

Ocean is abundant in lithium resource, showing great potential to meet the rapidly growing demand for lithium-based energy storage systems. Electrodialysis-based lithium extraction is an environmentally friendly and energy-efficient technology. Nevertheless, exploration of Li + separation membranes with high selectivity and superior mechanical properties remains a challenge. Herein, we present a flexible composite membrane based on ceramic Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) lithium ion conductor and polyvinylidene fluoride (PVDF) polymer in an all-water electrodialysis system for efficient lithium extraction. LATP/PVDF membranes with different compositions and thicknesses as well as operation conditions are systematically investigated with simulated seawater. It was first discovered that Li + may release from LATP particles when subjecting to a strong electric field, leading to overestimation of Li + selectivity. Lithium mass balance between seawater feed and enriched solutions was proposed to verify the performance authenticity. The system was then employed to extract Li + from natural seawater to demonstrate its industrial viability. As a result, Li + concentration in enriched catholyte is 87 times higher than the natural seawater with a low energy consumption of 8.3 Wh g Li −1 . In addition, LATP/PVDF membrane shows superior separability for interfering ions with Li + /Na + , Li + /Mg 2+ and Li + /Ca 2+ selectivity of 22,040, 64,235 and 15,336, respectively. This study provides a method for efficiently extracting lithium from seawater, offering an important approach for ensuring sustainable lithium supply.

A new composite gel polymer electrolyte (PEO-Bp-LATP) membrane consisting of poly-ethylene oxide (PEO), benzophenone (Bp) and varying amounts of highly ion-conducting lithium aluminum titanium phosphate (LATP) particles was prepared by significant Ultraviolet (UV) technology. The as-prepared PEO-Bp-LATP electrolyte membranes showed improved mechanical properties and superior electrochemical performances in Lithium metal batteries (LMBs). Typically, PEO-Bp-15 wt% LATP showed highest ionic conductivity (σ = 3.3 × 10−3 S.cm− 1 ) at RT, a high Li-transference ( t Li + = 0.77 ) and wider electrochemical stability window (ESW) above 5 V as well as good mechanical strength (9.3 MPa). More significantly, the PEO-Bp-15 wt% LATP membrane has an excellent inhibitory effect on Li dendrite expansion in Li symmetric cells and presents a long term cyclic stability with current density of 2 mA/cm 2 over 1100 h for Li//PEO-Bp-15 wt% LATP //Li. Our results for the measurement of galvanostatic charge-discharge deliver fascinating rate performance at 0.1C. Hence, the present study demonstrates that the UV-irradiated PEO-Bp-LATP membrane can be a promising electrolyte to meet the requirements for the next-generation LMBs.

Template-regulated Li 0.33 La 0.56 TiO 3 (LLTO) powders are synthesized using CTAB via a hydrothermal method. The hybird LLTO is obtained by mixing the template-regulated LLTO powders with Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) powders and non-templated LLTO powders. In the non-templated LLTO, small round grains develop, while large grains with a high aspect ratio tend to form in the template-regulated LLTO. The total conductivity of the hybrid LLTO increases, reaching 1.28×10 −4 S cm −1 . The presence of specific mesopores and the bridging effect among grains create an optimal balance between the mobility and density of lithium ions, therefore contributing to the increase of the conductivity. The hybrid LLTO demonstrates improved higher fracture toughness, indicating a greater cycling tolerance. It also exhibits superior initial capacity and a slower degradation rate. These results present a novel approach to prepare lithium-ion conductors with enhanced performance.

The escalating global demand for lithium necessitates efficient extraction methods, particularly from natural sources such as brine. Herein, we report a novel, thin, and dense functionalised composite ceramic membrane that is employed in conjunction with electrodialysis technology for selective lithium extraction from salt lakes. This membrane exhibits high mechanical strength, low ionic impedance, and high lithium conductivity. The thin functional layer, ~20 μm-thick NASICON-type Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) superionic conductor material, is deposited on high-strength and porous alumina membrane via a facile dip-coating method, providing structural stability for the composite membrane. The preparation and sintering processes of LATP-Al 2 O 3 ceramic composite membrane were systematically studied and precisely controlled to improve its morphology and performance. A membrane-based electrodialysis set-up was designed specifically for lithium extraction demonstrated the remarkable performance of the composite-LATP membrane in separating lithium from magnesium-lithium solutions with a high Mg/Li ratio. The LATP composite membrane effectively reduced the Mg/Li ratio from 40 to 2.1 after three-stage electrodialysis. Moreover, the Li + recovery reached 77.15% from the feed solution with an estimated power consumption of ~47.6 kWh per 1 kg of lithium carbonate. These findings have significant implications for the development of low-cost and environmentally friendly inorganic membrane separation technologies, which are important for promoting technological innovation in the lithium industry chain.

Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 is regarded as one of the most promising solid electrolytes for all solid state lithium ion batteries (ASSLIBS). However, its grain boundary conductivity is still low, which reduces the total conductivity of electrolyte. In this work, in order to further improve the electrical conductivity of Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 , a series of Y doped Li 1.3 Al 0.3-x Y x Ti 1.7 (PO 4 ) 3 (x = 0, 0.025, 0.05, 0.075 and 0.15) solid electrolytes were synthesized using a modified solid state method. Effects of Y doping content on morphology, phase and electrical conductivity of Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 electrolyte materials were systematically investigated. All synthetic electrolyte powders show Nasicon-like structure, well-shaped polyhedral morphology as well as good crystallinity. Y dopant content has a great influence on electrochemical properties of electrolytes. The high total conductivity of 7.8 × 10 −4 S/cm at room temperature and a low activation energy of 0.17 eV is obtained for the electrolyte with the Y doping content of 0.075 due to the increasing of grain boundary conductivity, and its electrical conductivity is about 2 times larger than that of the undoped electrolyte. The excellent electrochemical performance is mainly attributed to high electrolyte density which results from the good sintering property of electrolyte materials as well as the existence of YPO 4 phase at grain boundaries. Additionally, this electrolyte has a negligible electronic conductivity. These results suggest that Y doped Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 can be used as an alternative solid electrolyte for all solid state lithium ion batteries.
