As expected, a desired electrochemical energy storage system can simultaneously combine the low-cost raw materials with ultra-high energy density and no performance degradation characteristics. Here, we use liquid lithium as the anode, solid antimony as the cathode, molten LiF–LiCl–LiBr (or molten LiF–LiCl) as the electrolyte and test the battery at 550 °C. It can provide the energy density as high as 421.6 Wh kg −1 , while the energy storage cost is only 42.4 $ kWh −1 . More importantly, due to the self-healing characteristic of the pure antimony electrode, no capacity fading is observed during 470 cycles. Therefore, with all the merits, the Li||Sb liquid metal battery has become a competitive choice in the field of grid-level energy storage.

This study tackles the poor low-temperature performance of lithium-ion batteries through a synergistic strategy that modulates electrode–electrolyte interfacial chemistry via coordinated temperature and electric field control. The research uncovers distinct interfacial evolution mechanisms: at −20 °C, strengthened solvent–Li + affinity causes solvation structure reorganization and interfacial deterioration, whereas at 25 °C, enhanced anion participation promotes formation of stable inorganic-rich interphases. Reduced electric field intensity further facilitates the construction of stable interfaces. Based on these findings, a variable-temperature constant-current cycling protocol with periodic room-temperature activation is developed. This approach effectively restores stable interfaces and substantially minimizes polarization, enabling commercial lithium iron phosphate (LFP) batteries to maintain nearly 100% initial capacity after 150 cycles at −20 °C—significantly surpassing conventional strategies (80.4% retention). Notably, this optimization method regulates interfacial chemistry through external field parameters without electrolyte formulation changes, demonstrating both theoretical innovation and engineering practicality. This work provides a novel paradigm for low-temperature battery design by decoupling interfacial regulation from material modification.

Magnesium-lithium (Mg-Li) alloys are promising lightweight materials for engineering applications, but their use is limited by poor wear and corrosion resistance. To address those challenges, micro-arc oxidation (MAO) coatings were fabricated on Mg-Li alloy LA81 using electrolytes containing conductive ceramic nanoparticles (TiBCN). Results suggest that TiBCN enhances electrolyte conductivity and altering the arc discharge behavior, thereby reducing overall porosity of the resultant MAO coatings. Comprehensive characterization including measurements of coating thickness, microstructure, triboelectrochemical and corrosion resistance identify 2.5 g/L TiBCN as the optimal concentration. This formulation exhibits enhanced corrosion resistance, wear resistance and a notably low pore density. Three-dimensional evolution of corrosion in the optimized MAO coating was examined using synchrotron X-ray computed tomography. In corrosive environments, the combined effects of corrosion and expansion of corrosion products alter size, shape, and number of microdefects in MAO coatings over time. These changes were driven by the interactions between localized corrosion propagation and the accumulation and expansion of corrosion products. Ultimately, neighboring micro-defects merged, forming interconnected through-pores and accelerating MAO coating degradation.

The lithium dendrite problem of Li 7 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) solid electrolyte restricts the practical application and development of all-solid-state lithium batteries (ASSLBs). Herein, a LiPON interlayer with Li + conductive and electron non-conductive dynamic properties is constructed at the Li/LLZTO interface. Results show that the electronic conductivity of solid electrolyte after LiPON modification decreased by nearly three orders of magnitude, indicating that it has good ability to hinder electron conduction . The interlayer enhances the wettability between the Li metal anode and LLZTO, resulting in a decrease of battery resistance from 3400 Ω to 700 Ω. The critical current density of the ASSLBs increase from 0.1 mA cm −2 to 1.2 mA cm −2 at room temperature, and the battery cycle number increase from 31 h to over 1000 h. XPS deep etching results show that the LiPON/LLZTO interface has good electrochemical stability. The Kelvin probe force microscope displays a sharp increase in potential within the LiPON interlayer, indicating its successful hindrance of electron conduction to the solid electrolyte. The effective inhibition of lithium dendrites growth is due to LiPON can promote the Li + transmission from LLZTO solid electrolyte to Li anode, and also hinder the electron conduction to LLZTO to form lithium dendrites.

The technology of solid-state lighting has developed for decades in various industries. Phosphor, as an element part, determines the application domain of lighting products. For instance, blue and red-emitting phosphors are required in the process of plant supplementing light, arrow-band emitting phosphors are applied to backlight displays, etc. In this work, a Bi 3+ -activated blue phosphor was obtained in a symmetrical and compact crystal structure of Gd3SbO7 (GSO). Then, the co-doping strategy of alkali metal ions (Li + , Na + , and K + ) was used to optimize the performance. The result shows that the photoluminescence intensity is increased by 2.1 times and 1.3 times respectively by introducing Li + and K + ions. Not only that, it also achieves narrow-band emitting with the full width of half-maximum (FWHM) reaching 42 nm through Na + doping, and its excitation peak position also shifts from 322 to 375 nm, which can be well excited by near-ultraviolet (NUV) light emitting diode (LED) chips (365 nm). Meanwhile, the electroluminescence spectrum of GSO:0.6 mol%Bi 3+ ,3 wt%Na + matches up to 93.39% of the blue part of the absorption spectrum of chlorophyll a . In summary, the Bi 3+ -activated blue phosphor reported in this work can synchronously meet the requirements of plant light replenishment and field emission displays .

All-solid-state lithium batteries (ASSLBs) empolying sulfide solid electrolyte and lithium metal anode can afford improved energy density and safety. However, their large-scale application is hampered by the rigidity of ceramic–based electrolyte and the inevitable growth of lithium dendrites . Herein, a novel, flexible, high-conductivity and free-standing sulfide electrolyte membrane (Li 6 PS 5 Cl-polypropylene carbonate6, (LPSCl-PPC6)) with a thickness of 60 μm is prepared via methodology of blade coating and hot pressing, which exhibits a high Li + conductivity (3.1 × 10 −3 S cm −1 at 25 °C) and a wide electrochemical window (4.7 V vs Li + /Li) at 25 °C. Additionally, a bifunctional interphase with Li-Zn/LiCl is implanted on lithium metal surface to enhance the stability of electrolyte/lithium anode, which effectively prevents the growth of lithium dendrites and the internal short circuit of lithium symmetric battery. Benefiting from the synergistic effect, the assembled ASSLBs of S-CNTs/LPSCl-PPC6/Li-Zn/LiCl|Li and LLZO@NCM93/LPSCl-PPC6/Li-Zn/LiCl|Li exhibit high initial capacity of 1183.5 mAh g −1 (193.6 mAh g −1 ) and exceptionally cyclic stability with capacity retention of 89.2% over 150 cycles at 0.05C (93.2% over 100 cycles at 0.1C). This highly conductive sulfide-based composite electrolyte and interface engineering provides a promising strategy for achieving high performance ASSLBs.

Interfacial engineering is a decisive factor in stabilizing layered oxide cathodes for sodium-ion batteries (SIBs). Here, a synergistic Li/Mg/Si tri-doping strategy is introduced to simultaneously modulate the bulk lattice and interfacial chemistry of a P2-type Na 0.7 Li 0.03 Mg 0.05 Ni 0.25 Mn 0. 6 Si 0.07 O 2 (LMNMS) cathode. The dopants expand the c-axis lattice (11.195 Å) and strengthen surface transition metal (TM)-O covalency, yielding improved Na + diffusion kinetics and interfacial stability. X-ray photoelectron spectroscopy (XPS) and in situ Raman analyses reveal reduced surface oxygen vacancies (15% vs. 22% in the undoped sample) and suppressed electrolyte-induced oxygen redox, effectively mitigating the P2 → O2 phase transition. Electrochemical impedance spectroscopy confirms a 45% decrease in charge-transfer resistance, indicating enhanced interfacial charge transport. Benefiting from this coupled bulk-surface optimization, LMNMS delivers a high reversible capacity of 165 ± 3.2 mAh g −1 at 0.1C, an excellent rate performance (92 ± 2.5 mAh g −1 at 5C), and 90.5 ± 1.8% capacity retention after 200 cycles. This work highlights how multi-site doping tailors both the electronic and chemical nature of electrode interfaces, offering a design paradigm for high-performance and interface-stable sodium-ion batteries.

Polyamide/polyethylene (PA/PE) nanofiltration (NF) membranes based on polyethyleneimine (PEI) had demonstrated excellent Li + /Mg 2+ selectivity, but showing trade-off between their permeance and Li + /Mg 2+ selectivity. In this work, a novel cross-substrate counter diffusion (CSCD) method was introduced to grow and secure ZIF-L particles in the PA layers. Specifically, rather than directly contacting the PA layers containing Zn(II) cation (PA/Zn) with an aqueous solution of 2-methylimidazole (2-MIM) ligand from the top sides, 2-MIM ligand molecules were diffused across the PE substrate from the bottom sides to react with Zn(II) secured on the top sides of PA layers. Compared with the top-down method, the bottom-up approach had yield PA/ZIF-B NF membranes with higher surface roughness, larger average pore size and narrower pore size distribution. Notably, the pure water permeance of PA/ZIF-B membrane was increased by 2.6-folds to 15.1 L·m −2 ·h −1 ·bar −1 at a high Li + /Mg 2+ separation factor (S Li/Mg ) of 16.5, breaking the trade-off performance upper bound between water permeance and Li + /Mg 2+ separating selectivity and outperforming most of the reported TFN NF membranes.

A novel bis-quaternary ammonium salt was synthesized. • The bis-quaternary ammonium salt was used as an aqueous co-monomer to enhance the size sieving and charge exclusion effects of the nanofiltration membrane. • The Li + /Mg 2+ separation factor of the optimized membrane reached 73.3, which is 5.4 times that of the pristine membrane. Efficient separation of Li + and Mg 2+ from salt lakes is important for the application and recovery of lithium resources. In this work, a novel bis-quaternary ammonium salt (QTMPDA) was synthesized and utilized as a co-monomer in the polyethyleneimine aqueous solution for interfacial polymerization (IP), synergistically regulating the pore structure and surface charge of the nanofiltration membrane and improving its Li + /Mg 2+ separation performance. The QTMPDA monomer features a linear short-chain diamino structure, enabling it to participate in the IP, increase the crosslinking density of the polyamide network, and form a more concentrated pore size distribution, thereby enhancing the membrane's size sieving effect. Meanwhile, the two quaternary ammonium cations in QTMPDA can effectively increase the membrane surface electropositivity, strengthening the electrostatic repulsion of Mg 2+ . Relative to the unmodified membrane, the zeta potential of the optimized membrane was elevated from −5.9 mV to 20.2 mV at pH 7 and the MgCl 2 rejection was increased from 93.3% to 99.2%. Moreover, the membrane demonstrated an excellent Li + /Mg 2+ separation factor of 73.3 (mass ratio of Mg 2+ /Li + = 100). This work offers a novel approach for regulating IP process via functional aqueous co-monomers to optimize membrane structure and performance.

Neutral organic phosphate/FeCl 3 systems are widely employed for lithium extraction from high Mg/Li ratio brines; however, extractant degradation under prolonged operational conditions constrains process sustainability. This study investigates the degradation behavior of tributyl phosphate (TBP) and trioctyl phosphate (TOP) during lithium extraction, examining the influence of key process parameters (HCl/NaOH concentration, temperature, and FeCl 3 concentration) and evaluating the impact of degradation products on extraction performance. Single-factor experiments demonstrated that TOP exhibited superior stability compared to TBP, attributable to its longer carbon chains and greater steric hindrance. Both extractants displayed poorer acid resistance, whereas elevated FeCl 3 concentrations significantly suppressed degradation. On the basis of these findings, optimal process conditions are recommended: minimal HCl usage, NaOH concentration ≤ 4.0 mol·L −1 , and temperature ≤ 35 °C. Qualitative and quantitative 31 P NMR analyses confirmed that the primary degradation product of TBP was dibutyl phosphate (DBP), while that of TOP was di-(2-ethylhexyl) phosphoric acid (D2EHPA). Subsequent single-stage extraction experiments revealed that both DBP and D2EHPA diminished lithium extraction efficiency and Li/Mg separation factors, with D2EHPA exerting a more pronounced adverse effect. Across the concentration range of 0–0.5 mol·L −1 , D2EHPA reduced lithium extraction efficiency by 20%, compared to an 11% decrease caused by DBP. This study addresses a critical gap in understanding how extractant degradation affects long-term lithium extraction performance, and supplies feasible operational limits and formulation references for the industrial design and steady running of lithium separation processes.

Synergistic extraction mechanism in TBP system was investigated. • Synergistic extraction system performs better at low lithium concentration. • TBP-DEC system exhibits higher β Li/Mg than other synergistic systems. • Reducing O's electric potential in C O of synergistic agents enhance lithium selectivity. This study investigates the extraction and selective separation of Li from solutions with a high Mg/Li ratio based on a synergistic extractant system involving tributyl phosphate (TBP). Different synergistic agents were investigated, including ethyl acetate (EA), butyl acetate (BA), diethyl carbonate (DEC), methyl isobutyl ketone (MIBK), N,N-Diethylacetamide and N,N-di(1-methylheptyl)acetamide (N503). The result showed that TBP-DEC synergistic extraction system achieved the highest lithium extraction rate of 71.4% and lithium magnesium separation factor of 160, when the concentration of Li = 0.50 g/L and Mg/Li ratio = 200. Fourier Transform Infrared Spectroscopy (FT-IR) analysis revealed that TBP acted as the primary extraction agent for lithium extraction, while the O atom in the C O group of the synergistic agent participates in coordination with lithium. Additionally, the lithium extraction rate of the synergistic extractant system increased with the integrated peak area of the P O stretching vibration. Mechanism analysis reveals that increase of the negative charge density on the O atom in the C O group and reduction of the intermolecular steric hindrance of the synergistic agent can enhance the lithium selectivity of TBP.

The development of high-performance narrowband near-infrared second window (NIR-II) phosphors remains a critical challenge in the fields of advanced bioimaging and optical thermometry. Herein, a series of Mn 5+ -doped ABaPO 4 (A = Li, Na, K) phosphors are synthesized via conventional solid-state method, and the effect of A-site alkali metal cations on their crystal structure and luminescence properties is comparatively investigated. Mn K -edge X-ray absorption near-edge structure (XANES) spectroscopy unambiguously confirms that Mn ions are predominantly stabilized in the +5 oxidation state and exclusively occupy tetrahedral [PO 4 ] sites in all three hosts. All samples exhibit characteristic narrowband NIR-II emission in the 1160-1200 nm range originating from the 1 E → 3 A 2 spin-forbidden transition of Mn 5+ . The lattice distortion induced by different A-site cations significantly modulates the doping limit, crystal field strength, thermal stability and temperature sensing performance of Mn 5+ ions. All three Mn 5+ -doped hosts exhibit good thermal stability. The fluorescence decay lifetime of LiBaPO 4 : Mn 5+ reaches 772.436 μs NaBaPO 4 : Mn 5+ shows unique energy level splitting and achieves a maximum relative temperature sensitivity of 2.43% K −1 based on the fluorescence intensity ratio technique. KBaPO 4 : Mn 5+ possesses a highly symmetric crystal lattice and a higher doping limit, with a thermal quenching activation energy ( ΔE ) of 0.414 eV. This work not only provides three promising NIR-II phosphors for bioimaging and optical thermometry, but also offers new insights into the research of Mn 5+ -activated phosphate systems.
