Lithium extraction from salt lakes represents a crucial approach to developing lithium resources and plays a vital role in advancing the global energy transition. China possesses abundant lithium resources in its salt lakes. However, the high sodium content present in salt lake brines presents a significant challenge to efficient lithium extraction. This study investigates the capability of the LiFePO 4 -Zn battery system for extracting lithium from salt lake brine with a high Na + /Li + ratio. The system demonstrates a significant rejection effect on Na + and exceptional selectivity for Li + , even in high-concentration sodium ion aqueous solutions. In a chloride aqueous solution containing 0.25 g/L of Li⁺ and 100 g/L of Na⁺, the sodium-to-lithium mass ratio decreased from 400 to 13.52 after three cycles, indicating that the extraction efficiency of Li⁺ achieved reached 90.28 %.

Li dendrites caused by nonuniform Li plating and locally concentrated ion/electron flux would give rise to poor cycling performance and safety issues of short-circuit and so on. Herein, a functional nanolayer consisting of Indium Tin oxide (ITO) nanoparticles on 3D Cu foam was fabricated as case study to understand the mechanism of metal oxides on anchoring Li metal spots and how initial Li nucleation influences the following dendrites growth. Based on the experimental and theoretical results, it is demonstrated that not only the pristine metal oxides have higher binding energy with Li atom, but also in situ formed alloy phase during alloying process performs a great importance on homogeneous nucleation, thus leading to ordered ion/electron distribution and fast kinetics. Therefore, excellent wettability and even self-propagation behavior between ITO-Cu foam and molten Li are achieved, meanwhile the half cells with ITO-Cu foam electrodes exhibit an ultralow nucleation overpotential of 2 mV under 0.5 mA cm −2 . When the designed ITO-Cu foam@Li anodes is matched with LFP (LiFePO 4 ) cathodes, the constructed full cells can empower superior cycling stability for over 1000 cycles at 5C (3.4 mA cm −2 ), and remarkable specific capacity (149 mAh g −1 ) and capacity retention (80% for 250 cycles) even with ultrahigh mass loading (15.3 mg cm −2 ), which provides an avenue to regulate Li deposition/dissolution for high energy Li metal batteries.

For lithium extraction processes from liquid lithium resources, surmounting the interference of coexisting ions on the selective extraction of Li + − especially the selective separation of Mg 2+ and Li + − presents a challenging task. UIO-66 and HKUST-1, both metal-organic frameworks (MOFs), are synthesized using organic ligands with benzene ring groups. To boost the Li + adsorption and recognition capabilities of these two materials, LiNO 3 was introduced as a template, which not only constructs a Li + -size-adapted microenvironment within the adsorbent framework but also functions as a mineralizer, facilitating the formation of more uniformly sized crystals. The modified Li/UIO-66 and Li/HKUST-1 achieved maximum Li + adsorption capacities ( Q ) of 35.57 and 26.33 mg/g, respectively, reaching adsorption equilibrium within approximately 3 h. Li/UIO-66 showcases excellent Mg 2+ /Li + separation performance and maintains certain separation factor even in mixed solutions containing multiple interfering ions. Although Li/HKUST-1 demonstrates a stronger tendency for selective adsorption of higher-valent ions, it holds promise for the removal of interfering ions from solutions, thereby contributing to the overall optimization of lithium extraction processes.

The recycling of spent LiCoO 2 batteries has attracted numerous attentions in view of their environmental and economic values. However, conventional hydrometallurgy strategies for spent LiCoO 2 recycling still undergo complicated processes that involve multiple steps, resulting in a high-value metal loss and a low value-added product. Herein, a facile method was developed to recycle lithium and repurpose oxygen vacancy-rich cobalt-based catalysts toward oxygen evolution reaction (OER). By roasting LiCoO 2 with ammonium sulfate salt at 975 °C for 120 min, lithium was converted into soluble Li 2 SO 4 and 99.2 % of Li could be preferentially leached by H 2 O, while cobalt was recycled in the form of highly pure cobalt oxide (M−CoO). Importantly, the M−CoO exhibited an excellent OER activity, superior to the spent LiCoO 2 , the prepared Co 3 O 4 , the commercial RuO 2 , and most of the reported cobalt-based catalysts. The results confirmed that the outstanding OER activity of M−CoO was originated from the rich surface oxygen vacancy, which facilitated the surface reconstruction to form a highly active layer of short-range order species during OER. This study showcased a novel approach to achieving a priority lithium recovery, coupled with an advanced route for catalyst regeneration, from spent lithium-ion batteries for energy conversion and storage devices.

The increasing need for energy storage devices with high energy density has led to significant interest in Li-metal batteries (LMBs). However, the use of commercial electrolytes in LMBs is problematic due to their flammability, inadequate performance at low temperatures, and tendency to promote the growth of lithium dendrites and other flaws. This study introduces a localized high-concentration electrolyte (LHCE) that addresses these issues by employing non-flammable electrolyte components and incorporating carefully designed additives to enhance flame retardancy and low-temperature performance. By incorporating additives to optimize the electrolyte, it is possible to attain inorganic-dominated solid electrolyte interphases on both the cathode and anode. This achievement results in a uniform deposition of lithium, as well as the suppression of electrolyte decomposition and cathode deterioration. Consequently, this LHCE achieve over 300 stable cycles for both LiNi 0.9 Mn 0.05 Co 0.05 O 2 ||Li cells and LiCoO 2 ||Li cells, as well as 50 cycles for LiNi 0.8 Mn 0.1 Co 0.1 O 2 (NCM811||Li) pouch cells. Furthermore, NCM811||Li cells maintain 84% discharge capacity at −20 °C, in comparison to the capacity at room temperature. The utilization of this electrolyte presents novel perspectives for the safe implementation of LMBs.

With the increasing application of electric vehicles, the surging of lithium-ion batteries (LIBs) may foreshadow potential environmental disruptions stemming from mishandling spent LIBs and greenhouse gas emissions from recycling. Urgent advancements are needed in the current recycling technologies for dead LIBs. Herein, we propose a solution to address the challenge of industrial LIB waste recycling by repurposing it into environmentally friendly functional materials. Specifically, unitary and ternary transition metal organic frameworks (TT-MOFs) were successfully synthesized for use in the separator for high-performance lithium-sulfur (Li-S) batteries. The unique ternary MOFs demonstrate the capability to mitigate the shuttle effect and enhance the adsorption and conversion of lithium polysulfides during cycling. Notably, we achieved an initial discharge capacity of 1008.7 mA h g–1 at 0.5 C, with a decay rate of only 0.054% after 500 cycles. This research reuses waste solutions from the wet metallurgy process of LIB recycling and unveils a promising approach for the development of sustainable energy-storage materials in the future.

The Li + concentration and Li + transport channel size of garnet-type solid electrolyte Li 7 La 3 Zr 2 O 12 are the two key factors associated with the improvement of Li ionic conductivity . Through precise control of the Li + concentration and the Li + transport channel size by Ta-doping (Li 7-X La 3 Zr 2-X Ta X O 12 , X = 0.2–1.0), synergistic regulation of the two factors is achieved. Results show that the optimum Li + concentration seems to be at about 6.31 where the Li + occupancy in LiO 6 is high and the Li + arrangement in LiO 4 is disordering. With the Li + concentration higher than 6.31, the occupancy in LiO 4 sites remains constant but the Li + arrangement in LiO 4 becomes more and more ordering. At higher Li + concentration of 6.52, Li + arrangement becomes certain of ordering which should have reduced the grain conductivity, however, the grain conductivity is still as high as 9.84 × 10 −4 S cm −1 . This indicates that LLZO with this Li + concentration have favorable Li + transport channel size. The optimum Li + transport channel size is about 12.95 ± 0.01 Å. At Li + concentration of 6.31, the proper Li + concentration is the main factor for the high grain ionic conductivity of 10.1 × 10 −4 S cm −1 . While at Li + concentration of 6.52, the suitable Li + transport channel size is the main factor for the high grain ionic conductivity. In conclusion, the high grain ionic conductivity at Li + concentration of 6.31–6.52 is due to the synergistic regulation of Li + concentration and Li + transport channel size.

Ionically conductive polymers are a promising family of electrolytes for electrochemical devices, including batteries, and flexible electronics. The polymer electrolytes with an excellent mechanical property probably can inhibit the dendrites growth during charging/discharging. Herein, the mechanical properties of an N −methyl− N −propyl piperidinium bis(trifluoromethanesulfonyl)imide/poly(vinylidene fluoride-hexafluoropropylene) gel polymer electrolyte is improved through compositing with %TiO 2 nanoparticles. The gel polymer electrolyte shows increased loss modulus after compositing with 5 wt% TiO 2 , indicating that the inorganic nanoparticles can increase the viscous response of polymer electrolytes. The Li-ion conductivity shows a noticeable dependence on %TiO 2 and the highest ionic conductivity is obtained at 5 wt% TiO 2 . The presence of TiO 2 in the gel polymer electrolyte also allows for smaller interfacial resistance and a more stable Li−electrolyte interface upon long-term storage and battery cycling. As a result, when assembled with the LiFePO 4 and LiNi 0.6 Mn 0.2 Co 0.2 O 2 cathodes, the composite gel polymer electrolyte improves the full-cell performance, such as higher Coulombic efficiency, improved cycling stability, and more stable electrode–electrolyte interface.

Herein, inspired by previous reports on the electrochemical reduction of Al in diverse electrolyte systems, we describe a novel Al-containing solvate ionic liquid (2:1 (mol/mol) mixture of ethylene carbonate (EC) and AlCl3) that allows low-temperature electrochemical deposition of Al and features the advantages of low cost, ease of preparation, and high electrochemical stability. Electrodeposition of Al-Li alloy and Li can also be realized in this system. Additionally, the above ionic liquid exhibited a saturated vapor pressure of 0.0012 kPa and a conductivity of 1.32 mS/cm at 298 K, which was acceptable for practical applications. To elucidate the electrochemical deposition mechanism, the ionic components of the 2:1 EC/AlCl3 system were characterized by a range of instrumental analysis techniques and theoretical calculations, and Lewis-acidic cations were identified as the electroactive species for Al electrodeposition. Notably, an Al-Li alloy could be obtained by co-deposition in the new solvate ionic liquid, and Li metal could also be electrodeposited on a high-purity Al plate in the form of Al4Li9 and Li3Al2 under ambient conditions using LiCl as a Li source. Al-containing solvate ionic liquids, which to an extent evolved from organic-salts, are of increasing interest. They are expected to gain more attention in the field of electrochemical metallurgy of active metals, due to their higher tunability and lower price.

All solid-state battery (ASSB) as the breakthrough of the advanced lithium-ions battery owing to its superior energy density and safety. Solid electrolytes are required to possess excellent electrochemical and safety. However, the low ionic conductivity and the poor interfacial compatibility, respectively, limits the progress of polymer and ceramic electrolyte , which accelerate the development of composite solid electrolyte (CSE). Therefore, we demonstrate a hierarchy structure that PEO(polyethylene)-LLZO@NFPAN-SiO 2 , which consists of SiO 2 particles encapsulated nanofibers (in-situ hydrolyzed by TEOS) and flexible membrane of PEO-LLZO to synergistically elevate the performance of CSE. This CSE exhibits broad electrochemical window (6 V vs. Li) and strong ionic conductivity (3.3 × 10 −4 S cm −1 , 30 °C), and also shows robust strength (5.1 MPa). The assembled Li-symmetric cells exhibit superior cycling life of 1000 h, with an extremely modest over potential of 45 mV. The full cell exhibits excellent cycle stability, 102 mA h g −1 after 100 cycles at 0.5C, and a high initial Coulomb efficiency of 68 %. Skeleton-flesh structure is constructed by in-situ particle-embedded nanofiber and covered polymer, which strengthened mechanical capability, compatibility, inhibition of lithium dendrites , and introduced multi-Li + transport pathways, ensuring high safety and superior electrochemical performance for the applications of ASSBs.

Increasing the cut-off voltage of cathodes can improve the energy density of Li||LiCoO 2 batteries. However, the electrolyte and cathode suffer from oxidation and deterioration at high voltage, respectively, which lead to rapid battery degradation. Herein, a uniform, highly Li + conductive cathode electrolyte interphase (CEI) is constructed by using bis-(benzenesulfonyl)imide (BBSI) as an additive to stabilize Li||LiCoO 2 batteries at 4.6 cut-off voltage with superior cycling and high-rate performance. Such a CEI is comprised of LiF and conductive Li + moieties (e.g., Li 2 S and Li 3 N), which can improve the Li + migration, alleviate cathode degradation, and other secondary degradation factors caused by uneven local Li + intercalation/deintercalation. As expected, Li||LiCoO 2 batteries with a 1% BBSI-containing electrolyte sustain 81.30% of initial capacity after 300 cycles at 0.5C, and 88.27% of initial capacity even after 500 cycles at 2C/3C.

A series of Li-rich Mn-based layered material Li1.2Ni0.13Co0.13Mn0.54O2 (LMR) with different particle sizes and particle-size distributions (PSDs) have been successfully synthesized via a combustion method using different manganese sources. The particle size of the N-LMR material prepared using Mn(NO3)2·4H2O as the manganese source is the smallest, and its PSD range is the narrowest among all of the samples. The unique particle size and PSD have a great influence on the electrochemical kinetics of Li-ion extraction/insertion reactions, leading to enhanced electrochemical performance when used as a cathode material for both the half and full Li-ion cells, especially the specific charge capacity at high current rates. The value of the charge specific capacity will determine the state of charge at the initial discharge stage and then influence the discharge process of these Li-rich Mn-based oxides. The N-LMR electrode delivers an initial discharge capacity of 309.2 mA h g–1 at 0.1C, and the specific capacity can reach up to 208.1 mA h g–1 at 1C. After 140 cycles, the electrode can still maintain 95.6% of its initial specific capacity at 1C. Moreover, the material displays a superior high-temperature lithium storage property at 55 °C and the full cells using N-LMR as the cathode material also show a much better electrochemical performance.
