The recycling of spent ternary lithium batteries (T-LIBs) promises scarce strategic resource recovery, however, efficient and selective recovery of Li + from T-LIBs leaching solution with complex components is still a considerable challenge. Herein, we present a polyamide nanofiltration membrane based on the positively charged nanoscale dispersion interlayer for the first application in recycling lithium from the leaching solution of spent T-LIBs. The electronegativity is weakened by positive charge within the interlayer, which enhance the effect of Donnan exclusion. The pos-TFNi membrane can effectively permeate Li + while the interfering divalent ions are almost completely separated, achieving the high purity (separation factor ≥ 93.5) and high recovery rate (79.2%) of Li + from leaching solution simultaneously, with a 6.2-fold improvement in the separation factor over the pristine TFC membrane, and outperformed the majority of the NF membranes. This work represents a reference for the recycling of the massive accumulation of spent T-LIBs worldwide.

The development of high-energy-density Li-ion batteries is hindered by the irreversible capacity loss during the initial charge-discharge process. Therefore, pre-lithiation technology has emerged in the past few decades as a powerful method to supplement the undesired lithium loss, thereby maximizing the energy utilization of LIBs and extending their cycle life. Lithium oxalate (Li 2 C 2 O 4 ), with a high lithium content and excellent air stability, has been considered one of the most promising materials for lithium compensation. However, the sluggish electrochemical decomposition kinetics of the material severely hinders its further commercial application. Here, we introduce a recrystallization strategy combined with atomic Ni catalysts to modulate the mass transport and decomposition reaction kinetics. The decomposition potential of Li 2 C 2 O 4 is significantly decreased from ∼4.90V to ∼4.30V with a high compatibility with the current battery systems. In compared to the bare NCM//Li cell, the Ni/N-rGO and Li 2 C 2 O 4 composite (Ni-LCO) modified cell releases an extra capacity of ∼11.7 %. Moreover, this ratio can be magnified in the NCM//SiO x full cell, resulting in a 30.4 % higher reversible capacity. Overall, this work brings the catalytic paradigm into the pre-lithiation technology, which opens another window for the development of high-energy-density battery systems.

Lithium (Li) metal has been recognized as the most promising anode material for next-generation rechargeable batteries. However, the practical application of Li anodes is hampered by the growth of Li dendrites. To address this issue, a robust and uniform Sb-based hybrid lithiophilic protective layer is designed and built by a facile in situ surface reaction approach. As evidenced theoretically and experimentally, the as-prepared hybrid protective layer provides outstanding wettability and fast charge-transfer kinetics. Moreover, the lithiophilic Sb embedded in the protective layer provides a rich site for Li nucleation, which effectively reduces the overpotential and induces uniform Li deposition. Consequently, the symmetric cell exhibits a long lifespan of over 1600 h at 1 mA cm–2 and 1 mAh cm–2 with a low voltage polarization. Furthermore, excellent cycling stability is also obtained in Li–S full cells (60% capacity retention in 800 cycles at 1 C) and Li||LFP full cells (74% capacity retention in 500 cycles at 5 C). This work proposed a facile but efficient strategy to stabilize the Li metal anode.

The growth of lithium (Li) dendrites and the accumulation of dead Li (i.e., Li metal regions which are electronically disconnected from the current collector) significantly undermine the safety and performance of Li metal batteries. This study employs kilogram–scale atomic layer deposition technology to construct zinc oxide with a preferential (002) crystal orientation, which homogeneously forms on commercial carbon nanotube papers. Our approach emphasizes the importance of achieving a moderate Li adsorption energy and low Li migration energy barriers to suppress Li dendrite growth. In this work, we introduce the concept of “catalytic” effect for dead Li reconversion, as validated through time–of–flight secondary ion mass spectrometry, leading to a Li plating/stripping efficiency of 99.89%. The Ah–level Li metal pouch cells with high–nickel positive electrodes achieve a specific energy of 380 Wh kg −1 (based on the mass of the whole pouch cell) and demonstrate stable cycling under demanding conditions. Analysis of the cycled pouch cells confirms the structural integrity and provides insights into the mechanism of the dead Li “catalytic” conversion.

Rechargeable aprotic lithium (Li)-oxygen battery (LOB) is a potential next-generation energy storage technology because of its high theoretical specific energy. However, the role of redox mediator on the oxide electrochemistry remains unclear. This is partly due to the intrinsic complexity of the battery chemistry and the lack of in-depth studies of oxygen electrodes at the atomic level by reliable techniques. Herein, cryo-transmission electron microscopy (cryo-TEM) is used to study how the redox mediator LiI affects the oxygen electrochemistry in LOBs. It is revealed that with or without LiI in the electrolyte, the discharge products are plate-like LiOH or toroidal Li 2 O 2 , respectively. The I 2 assists the decomposition of LiOH via the formation of LiIO 3 in the charge process. In addition, a LiI protective layer is formed on the Li anode surface by the shuttle of I 3 − , which inhibits the parasitic Li/electrolyte reaction and improves the cycle performance of the LOBs. The LOBs returned to 2e − oxygen reduction reaction (ORR) to produce Li 2 O 2 after the LiI in the electrolyte is consumed. This work provides new insight on the role of redox mediator on the complex electrochemistry in LOBs which may aid the design LOBs for practical applications.

Lithium metal is an ideal anode material for lithium battery thanks to its ultra-high specific capacity and lowest redox potential . However, uncontrollable growth of lithium dendrites hinders its application due to local aggregation of lithium ions and anisotropic growth of lithium metal driven by uneven electric field distribution. Here a strategy is proposed to address this issue via utilizing porous equipotential body decorated with heterogeneous nucleation sites as advanced three-dimensional current collector. The conductive network of carbon nanofibers is recognized as a porous equipotential body, where the interior electric filed is zero due to the well-defined electric field shielding effect. In addition, copper nanoparticles as heterogeneous nucleation sites are uniformly anchored on carbon nanofibers, which guide lithium deposition evenly. As a result, lower impedance and higher Coulombic efficiency (∼97%) are achieved in modified lithium-copper cell. In particular, the cycling lifetime of modified symmetric lithium-lithium cell is expanded up to 500 cycles at extremely large current density of 50 mA cm −2 .

Li dendrite and the shuttle effect are the two primary hindrances to the commercial application of lithium–sulfur batteries (LSBs). Here, a multifunctional separator has been fabricated via successively coating carbon nanotubes (CNTs) and lithium phytate (LP) onto a commercial polypropylene (PP) separator to improve the performance of LSBs. The LP coating layer with abundant electronegative phosphate group as permselective ion sieve not only reduces the polysulfide shuttle but also facilitates uniform Li+ flux through the PP separator. And the highly conductive CNTs on the second layer act as a second collector to accelerate the reversible conversion of sulfide species. The synergistic effect of LP and CNTs further increases the electrolyte wettability and reaction kinetics of cells with a modified separator and suppresses the shuttle effect and growth of Li dendrite. Consequently, the LSBs present much enhanced rate performance and cyclic performance. It is expected that this study may generate an executable tactic for interface engineering of separator to accelerate the industrial application process of LSBs.

Lithium (Li) metal plays an indispensable role in Li-S batteries , but its fast degradation seriously impedes the practical application of Li-S batteries. Here, an ion-conductive LAGP-based composite protective layer (CPL) consisting of lithium aluminum germanium phosphate (Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 ) and polyvinylidene fluoride (PVDF) is prepared on Li metal anode via a facile casting method. In the presence of LAGP, the negative effect of CPL on the diffusion of Li + is minimized. Hence, it can not only effectively resist corrosive action of lithium polysulfides (LiPSs) on Li metal anode, but also reduce interfacial polarization and restrain dendritic Li growth. The protected Li anode exhibits exceptional cycling stability and low voltage polarization (∼30 mV at 0.5 mA cm −2 ) for 300 h. The electrochemical performance of Li-S batteries with protected Li anode is also greatly enhanced. The discharge specific capacity of 832.1 mAh g −1 and an average coulombic efficiency of 92% are obtained for up to 100 cycles at 0.5 C in LiNO 3 -free electrolyte. Additionally, the rate capability of Li-S batteries is significantly improved, delivering a reversible capacity of 565 mAh g −1 at 4 C. Our results also indicate this protection strategy can be extended to the Li-S pouch cells.

Lithium (Li) metal is one of the most promising anode materials but suffers from inhomogeneous Li deposition, which is a limiting factor for the practical application of Li metal batteries. Some metals with high lithiophilicity are extremely recognized for achieving uniform Li deposition, but how these metals work is still unknown. Herein, the role of lithiophilic metals on the Li-plating process is explored on the basis of the experiments and theoretical calculations. The nucleation barrier is significantly reduced, owing to the alloying reaction between metals and Li species. The Li ions are subsequently attracted by the above favorable lithiophilic nucleus and conversed into Li atoms as a result of the high binding energy between the Li species and alloy nuclei. Besides, deposited Li diffuses into the electrode lattice via the channels with a low diffusion barrier. By construction of metal sites as well as the formation of alloy nuclei with high lithiophilicity, a dendrite-free anode can be realized. This study sheds fresh light on the lithiophilic electrochemistry and dendrite inhibition strategies for safe and high-energy-density Li metal batteries.

Li metal anode is considered to be the most potential battery anode due to its high theoretical capacity and low potential. However, Li dendritic growth hinders its practical application. Here, a stable Li-metal anode with a fluorinated hybrid layer is fabricated by a simple chemical-modification strategy. The stabilization of Li metal is attributed to the formation of chemical and mechanical stability hybrid protective layer consisting of bulk alloy and Li fluoride, which can effectively minimize the side reactions and suppress Li dendrite growth. With these advantages, the LiF/Li3Mg7-protected Li electrodes enable the Li||Li symmetric cell to maintain a stable overpotential of 25 mV at a capacity of 1 mAh cm–2 over 1800 h and enable the Li||LiFePO4 cell to a capacity of 134.5 mAh g–1 at 1 C for 200 cycles; the capacity retention rate is 98.6%.

Layered lithium aluminum double hydroxides (LiAl-LDH) have significant potential for industrial applications, particularly as adsorbents for lithium extraction from salt lakes. However, their development is constrained by a relatively low adsorption capacity. To address this limitation, a composite material comprising biochar (BC) and lithium aluminum layered double hydroxide (LiAl-LDH@BC) was synthesized via a hydrothermal reaction, using Al(NO 3 ) 3 ·9H 2 O, LiNO 3 , urea, and varying amounts of BC as raw materials. This composite demonstrates excellent Li + adsorption capacity (19.6 mg/g). LiAl-LDH@BC 2.5 was characterized using SEM, XRD, XPS, and other analytical methods. The effects of various adsorption conditions—including adsorption temperature, initial Li + concentration, time, pH, ion interference, and the number of cycles—on the Li + adsorption performance of LiAl-LDH@BC were investigated. The increased specific surface area and the electrostatic adsorption of surface functional groups after composite formation are the primary reasons for the high adsorption capacity. The mechanism of Li + adsorption follows pseudo-first-order kinetics and the Langmuir model, involving both physical and chemical adsorption. This study offers a promising adsorbent for the extraction of Li + from aqueous media.

Lithium-sulfur (Li-S) battery, as a promising next-generation high-energy-density battery, suffers from lithium polysulfides (LPSs) shuttle and Li dendrites issues. Porous crystalline framework-based membranes as separator can effectively absorb and restrain LPSs but without precise structural design principal exploration and mechanism studies. Herein, bio-inspired 1D oriented lithium-ion transport channels with molecular negatively charged PO 3 (−1) have been developed in hybrid tetrazole frameworks for promoting the transmission of Li + ions. The theoretical calculations and in situ spectroscopy demonstrated the higher binding energy and inhibited diffusion of LPSs in PO 3 . The assembled PP@PO 3 Janus separator in Li-S coin cell delivered a high initial capacity of 1410.9 mAh g −1 at 0.1 C and a low attenuation rate of 0.038% per cycle over 500 cycles at 5 C. Besides, the high capacities of 862, 542 and 409 mAh g −1 based on high-sulfur-loading cathodes of 2.6, 3.8 and 5.0 mg cm −2 at 0.5 C were achieved, respectively. Moreover, the punch battery of PO 3 @PP separator with S-cathode of 1.2 mg cm −2 has been developed for demonstrating its potentials commercial application, which displays impressive capacity of 873.4 mAh g −1 with the retention of ∼78.9% over 50 cycles.
