Nanofiltration (NF) membrane with high ion sieving efficiency is desired for Mg 2+ /Li + separation. To achieve this aim, a crown ether functional layer with a high Mg 2+ transportation barrier was constructed by grafting water-soluble diazo-18-crown-6 ether (DA18C6) monomer on the piperazine (PIP)-based polyamide NF membrane surface via secondary interfacial polymerization (SIP). Molecular simulations revealed that the crown ether monomer has a stronger interaction force with Mg 2+ (−355.9 kcal/mol) than Li + (−110.6 kcal/mol) due to its higher bonding energy, thereby reducing the diffusion rate of Mg 2+ . The ion separation experiment showed that the PIP-TMC-DA18C6 (5min) NF membrane demonstrated a better Mg 2+ rejection of 87.7 % compared with the pristine PIP-TMC NF membrane of 76.1 %. Besides, the Li + shows a higher mean square displacement (MSD) value in PIP-TMC-DA18C6 NF membrane than PIP-TMC NF membrane, resulting in a lower Li + rejection of 34.1 %. Furthermore, the PIP-TMC-DA18C6 (5 min) NF membrane also shows an excellent separation factor of 18 under the Mg 2+ /Li + ratio of 50:1. This work demonstrated that the crown ether-based composite NF membrane exhibits a good performance for Mg 2+ /Li + separation.

Solid-sate lithium-ion batteries (LIBs), especially lithium–sulfur (Li–S) batteries, are one of the most promising candidates for developing high energy density and high safety energy storage devices. However, current solid-state Li–S batteries can only work well at a relatively high operating temperature (>50 °C) due to the poor Li-ion transfer kinetics at electrodes/electrolyte and their interfaces which make these batteries lose most of their capacity and power as the temperature falls below room temperature. Here, we report an extra-wide operating temperature solid-state Li–S battery that can efficiently harvest omnidirectional solar energy and convert it into heat via a hierarchical copper–silicon nanowire photothermal current collector. Such a current collector enables broad solar spectrum absorption (>93%) with a wide incident angle (0 degree to 70 degree) and efficient conversion of light-to-heat, improving charge storage and transmission at electrodes/electrolyte and their interfaces even at low operating temperatures. As a result, the battery demonstrates low impedance (∼102 Ω cm2), a high discharge capacity of ∼900 mA h g−1 at room temperature, ∼960 mA h g−1 at 60 °C and a discharge capacity of ∼260 mA h g−1 at −60 °C. Such a design provides an effective solution for all-solid-state LIBs operating at a low temperature.

Gold nanoparticles (AuNPs) anchored to vertically aligned carbon nanotubes (VACNTs) act as additional nucleation sites for the Li2O2 growth, leading to the decreased size while increased density of Li2O2 particles in process of discharge. Correspondingly, at the deep discharge to 2.0 V the batteries show increased specific capacity. Upon charge, the AuNPs exhibit promotion effect on the Li2O2 decomposition by improving the conduction property of the discharge-formed particles, rather than by imposing the conventional electrocatalytic effect on the oxygen evolution reaction. Moreover, the AuNPs show promotion effect on decomposition of carbonate species arising from the side reactions. These effects consequently lead to the reduced charge overpotentials and extended cycle operation of the batteries. The results here provide a new as well as clear picture on the role of incorporated AuNPs in the Li2O2 formation and decomposition, which would be helpful for better understanding and constructing of high-performance air cathodes.

All-solid-state Li–O2 batteries are receiving intense interest because of the substitution of solid electrolytes for toxic and flammable liquid electrolytes. However, new issues are arising in the aspect of the electrolyte cathode interface. On the one hand, in a traditional sandwiched battery structure, the reaction sites of the cathode are restricted to the finite planar electrode–electrolyte interface, resulting in limited performance of all-solid-state Li–O2 batteries. On the other hand, integrating the electrolyte with the cathode to achieve good interfacial contact often requires complex sintering processes. Herein, this work reports a solid electrolyte cathode assembly (SECA) which consists of a dense Li1.5Al0.5Ge1.5P3O12 (LAGP) layer and a carbon coated porous LAGP layer fabricated by facilely one-step sintering. As a result, Li–O2 batteries adopting the SECA showed a relatively high discharge capacity of 0.48 mAh cm−2 at 5 μA cm−2. Besides, the batteries could sustain six full cycles with a restricted capacity of 0.08 mAh cm−2 at 10 μA cm−2. It was found that the high capacity can be attributed to the high surface area of porous cathode structure.

Lithium-rich manganese-based layered oxides (LLOs) are regarded as a kind of ideal cathode materials of the next-generation lithium-ion batteries owing to their exceptionally high theoretical capacity (>300 mAh g −1 ). Nevertheless, these cathode materials are subject to voltage decay and capacity fading due to the irreversible oxygen release and transition metal (TM) migration. Hence, a multisite doping strategy is proposed to interrupt the migration path of TM ions for LLO cathodes with superior structural stability. Moreover, multisite doping also offers pillar effect, and stabilizes lattice oxygen by the establishment of robust covalent P-O bonds to constrain the removal of electrons from the O 2p band. The P-Mg co-doped sample exhibits enhanced dynamic structural reversibility, lattice oxygen stability, and a significantly augmented resistance to electrolyte corrosion. Consequently, the co-doped sample shows outstanding capacity and voltage stability. Its capacity retention ratio is as large as 92.5 % even after 400 cycles, with a corresponding voltage decay rate of merely 0.688 mV/cycle. Multisite doping strategy presents an innovative approach to mitigating voltage decay and capacity fading of Li-rich Mn-based layered cathodes.

Practical application of lithium–air batteries (LABs) is hindered by volatile liquid electrolytes, which compromise cycling stability at both high and low temperatures. Herein, we propose an in situ strategy for the fabrication of an ether-in-gel electrolyte to enhance their performance. LiN(CH 3 ) 2 (LDA), formed from metallic Li and N,N-dimethylformamide, binds with TEGDME (G4) to create an LDA(G4) 2 matrix that confines liquid G4 and traces of DMF, forming a gel electrolyte. The strong Li + -O/N interaction between LDA and G4 enables high superoxide solubility and high intrinsic thermal stability. LABs with the gel electrolyte exhibit over 1250 h stability (>50 days) in ambient air with high energy efficiency of over 70% and maintain stable cycles (540 h at 55 °C and 800 hours at −20 °C) without significant capacity decay. This work paves the way for design of new ether-in-gel electrolytes for high-energy batteries under all climate conditions.

Owing to the unique structure and physicochemical properties, including high specific surface area , self-doped N atoms, open pore structure and good chemical stability, zeolitic imidazolate frameworks (ZIFs) and their derivatives have been widely used in the field of energy storage. Here, a new type of "cocoon"-like Zn/N doped ZIF-derived porous carbon (Zn@N-C-800) is synthesized as an anode for lithium-ion batteries (LIBs) and sodium ion batteries (SIBs) through a one-step carbonization process using a novel Zn-ZIF as the precursor. In Zn@N-C-800, the "cocoon"-like disordered carbon skeleton is conducive to electrolyte infiltration, while the Zn/N doping can provide additional active sites for ion storage. Benefiting from these unique structural characteristics, Zn@N-C-800 achieves excellent electrochemical performances as anode for both LIBs and SIBs: an ultrahigh rate capability of 352 mAh g −1 can be delivered at 12.8 A g −1 for LIBs; an outstanding long-term cycling stability (312 mAh g −1 at 1 A g −1 after 2000 cycles) can be achieved for SIBs. This paper provides new ideas for the design and preparation of high-performance anodes for LIBs and SIBs.

Membrane capacitive Li-extraction technology (MCLiE) emerges as a highly promising technology for extracting lithium from saline brines, catering to the surging demand for lithium resources. In this study, a positively charged polymeric membrane consisting of dopamine-polyethyleneimine is adhered to the surface of LiMn 1.9 Cr 0.1 O 4 @carbon cloth (LMC@CC/DA-PEI) via surface engineering strategy, which is then employed as a flexible electrode for Li-extraction assembled in the membrane capacitive deionization (MCDI) system. Experimental results confirm that the old brine from West Taijinar with high Li content and low Mg/Li ratio is proper for practical Li-extraction, and the initial discharge/absorption capacities of LMC@CC/DA-PEI-0.5 electrode are 105.9 mAh·g −1 /27.4 mg·g −1 . Following 200 cycles, capacity retentions of bare LMC@CC and LMC@CC/DA-PEI-0.5 are 43.40 % (13.5 mg·g −1 ) and 59.77 % (16.4 mg·g −1 ), respectively. Therefore, surface incorporation of DA-PEI mitigates structural degradation of LMC and stabilizes long-cycle (de)lithiation of Mn-based electrodes. Moreover, the high Li + selectivity (α Li/Mg = 156.7) is due to the spinel lattice of the LMC in combination with the electrostatic repulsion of the positively charged DA-PEI layer. Considering the strict environmental protection requirements and abundant new energy power supply in salt-lake areas, the assembled MCDI system with the DA-PEI-assisted LMC@CC electrode holds great potential for yielding enhanced Li + selectivity in the lithium recovery from old brine.

Composite polymer solid electrolytes (CPEs), possessing good rigid flexible, are expected to be used in solid-state lithium-metal batteries. The integration of fillers into polymer matrices emerges as a dominant strategy to improve Li + transport and form a Li + -conducting electrode–electrolyte interface. However, challenges arise as traditional fillers: 1) inorganic fillers, characterized by high interfacial energy, induce agglomeration; 2) organic fillers, with elevated crystallinity, impede intrinsic ionic conductivity, both severely hindering Li + migration. Here, a concept of super-ionic conductor soft filler, utilizing a Li + conductivity nanocellulose (Li-NC) as a model, is introduced which exhibits super-ionic conductivity. Li-NC anchors anions, and enhances Li + transport speed, and assists in the integration of cathode–electrolyte electrodes for room temperature solid-state batteries. The tough dual-channel Li + transport electrolyte (TDCT) with Li-NC and polyvinylidene fluoride (PVDF) demonstrates a high Li + transfer number (0.79) due to the synergistic coordination mechanism in Li + transport. Integrated electrodes’ design enables stable performance in LiNi 0.5 Co 0.2 Mn 0.3 O 2 |Li cells, with 720 cycles at 0.5 C, and 88.8% capacity retention. Furthermore, the lifespan of Li|TDCT|Li cells over 4000 h and Li-rich Li 1.2 Ni 0.13 Co 0.13 Mn 0.54 O 2 |Li cells exhibits excellent performance, proving the practical application potential of soft filler for high energy density solid-state lithium-metal batteries at room temperature.

Thermoelectric technologies (TEs) offer immense potential for waste heat recovery and energy storage. However, the practical application of current TEs has been severely hampered by potential performance degradation in extreme environments, particularly at high temperatures, due to electrolyte flammability or poor carrier mobility. The development of high-temperature, high-performance TEs is crucial for broadening their operational range and enabling diverse applications. Here, practical high-temperature high-voltage thermal charging cells (HHTCCs) are reported, facilitated by a heat-resistant trifluoromethanesulfonate-based Ca–Li dual-cationic ionic liquid electrolyte containing functionalized AmimCl solvent, together with a thermotolerant composite membrane, PEN(polyphenylene-ether-nitrile)@ZrBDC-F-4%. The dual-cation mechanism enables high thermal voltage through cooperative energy storage, while the functionalized AmimCl accelerates the mobility of Ca 2+ and Li + ions by weakening the surrounding shielding effect. Additionally, the anionophilic ZrBDC-F-4% nanoparticles in the composite membrane enhance carrier migration. As a result, the HHTCCs exhibit an impressive thermal voltage of 1.138 V, a remarkable thermopower of 15.3 mV K −1 , and an outstanding Carnot-relative efficiency of 9.56% over an unprecedented temperature range from 328.15 to 393.15 K, demonstrating the excellent safety and feasibility of HHTCCs. This work expands the service-temperature range of i-TEs, holding significant promise for high-temperature, high-performance waste heat harvesting.
