Lithium (Li) metal batteries offer high energy densities but suffer from uncontrolled lithium deposition, causing serious dendrite growth and volume fluctuation. Tailorable Li nucleation and uniform early-stage plating are essential for homogenous Li deposition. Herein, insertion type Li 3 VO 4 is first demonstrated as efficient lithiophilic sites trapping Li + ions for homogenous nucleation. By homogenizing the distribution of electric field and ions flux via an ingenious architecture design with Li 3 VO 4 nanodots grown on the carbon fibers (LVO@CNFs), leveling Li metal deposition after nucleation is also realized. These, together, result in smooth and dendrite-free Li deposition on the LVO@CNFs via a trapping-and-leveling model, giving rise to unprecedented performance (highly stable Li plating/stripping exceeding 2500 h at 2 mA cm −2 under 3 mA h cm −2 capacity, high-capacity retention of 82.5% over 500 cycles in a Li@LVO@CNFs//LiFePO 4 battery). The successful design of Li metal deposition host via insertion-type Li 3 VO 4 may pave a new way for long lifespan Li metal batteries.

Achieving flawless growth of metal-organic frameworks (MOFs) on carbon cloth is challenging and the influence of plasma on the growth of MOFs still needs to be examined. In this study, flawless zeolitic imidazolate framework-8 (ZIF-8) was grown on oxygen plasma activated carbon fiber and ZnO, N-dually doped hollow carbon web ( p -ZNCC) was obtained after sintering. The oxygen plasma generated numerous C O polar bonds on the carbon fiber, which ensures tightened uniform growth of ZIF-8 particles and promoting the formation of lithiophilic pyrrolic N and ZnO after sintering. This enables uniform lithium deposition and rapid lithium-ion diffusion during the operation. The resulting lithium electrode with the p -ZNCC host ( p -ZNCC-Li) exhibits stable lithium stripping/plating for up to 3000 h and a voltage hysteresis of 36 mV when cycled at 10 mA cm −2 -10 mAh cm −2 . Electrochemical impedance spectroscopy (EIS) reveals low charge transfer resistance and a high diffusion coefficient for p -ZNCC-Li. Moreover, the LNMO||p-ZNCC-Li cell demonstrates improved capacity retention at 1C after 250 cycles. This research is pioneering in using plasma to help grow metal-organic frameworks (MOFs) on carbon cloth that has lithiophilic spots, indicating significant progress in the development of lithium metal anode design.

Lithium metal batteries (LMBs) are anticipated to meet the demand for high energy density, but the growth of lithium dendrites seriously hinders its practical application. Herein, we constructed a kind of composite separator (ZIF-90@PP) consisting of zeolite imidazole framework-90 (ZIF-90) and polypropylene (PP) to promote the uniform deposition of Li+and inhibit the growth of lithium dendrites. The aldehyde groups interacting with TFSI−and the nitrogen-containing negative groups attracting Li+of ZIF-90 can facilitate the dissociation of LiTFSI to release more Li+, thus alleviating the influence of space charge near the electrode surface and accelerating the transfer of Li+. Not only does the excellent electrolyte wettability of ZIF-90 enhance the electrolyte retention capacity of the separator, but the orderly nano-channels in ZIF-90 also restrict the free migration of anions and homogenize the distribution of Li+. Consequently, the functional separator achieves a long-term stable Li plating/stripping cycling for over 780 h at 2 mA cm−2. Moreover, an impressive average coulombic efficiency of 98.67% at 0.5 C after 300 cycles is realized by Li || LFP full cells based on ZIF-90@PP with a capacity retention rate of 71.22%. The high-rate and long cycling performance of the modified Li || LFP cells further demonstrates the advantages of the ZIF-90@PP composite separator.

Aqueous zinc-ion batteries (AZIBs) have emerged as a prominent contender in energy storage devices, largely due to their substantial theoretical capacity, and competitive cost. Nevertheless, the uncontrollable proliferation of zinc dendrites and the emergence of parasitic side effects present a significant challenge to the practical implementation of AZIBs. Herein, a novel low-cost and environmentally friendly electrolyte additive, pullulan polysaccharide (PLL), was incorporated into a common ZnSO 4 electrolyte to stabilize the Zn anode of high-performance AZIBs. Experimental and theoretical calculations demonstrated that PLL can modulate the interaction of Zn 2+ with H 2 O molecules, reducing the number of H 2 O molecules around Zn 2+ and thereby facilitating the desolvation of Zn 2+ . Furthermore, the PLL molecules adsorbed on the surface of the zinc anode formed a protective layer that permitted the uniform deposition of Zn 2+ . As anticipated, the cycle life of the Zn//Cu asymmetric cells using 2M ZnSO 4 + 1 wt% PLL as the electrolyte exceeded 3700 cycles, with a high average Coulombic Efficiency of 99 %. The Zn//Zn symmetric cell with PLL as the electrolyte exhibited excellent cycling stability, demonstrating prolonged operational longevity that exceeded 1200 h. Furthermore, full cells with PLL additive displayed enhanced long-term durability when coupled with sodium vanadate (NVO) cathode.

Zinc corrosion, hydrogen evolution reaction, uneven deposition, and dendrite growth on the zinc anodes are the key factors restraining the electrochemical performance and cycling stability of the aqueous zinc-ion batteries. In this study, learned from the synial membrane, a tiny amount of natural amino acid β-alanine (β-Ala, 0.089 wt %) was introduced as the additive in ZnSO4 electrolyte for strengthening the kinetics of the zinc anode as well as enhancing the performance of zinc ions batteries. A number of modern surface techniques and surface electrochemical analyses were employed to reveal the fundamental reasons for the strengthened zinc anode by β-Ala in ZnSO4 electrolyte. The results show that β-Ala could be adsorbed on zinc electrode surface through intermolecular chelation, which might regulate the chemical environments of the electrolyte and promote uniform deposition of zinc ions. Hence, the β-Ala adsorption film on zinc electrode could suppress the hydrogen evolution reaction and the formation of zinc dendrites, thereby significantly improving the deposition/stripping process of the zinc anode. In particular, the strong hydrogen bonding could restrain the migration of H2O molecules approaching the zinc anode surface, preventing the invasion of water to the zinc electrode surface. Therefore, the addition of dilute β-Ala in the ZnSO4 electrolyte might remarkably prolong the life span of Zn||Zn symmetric batteries to 5000 h under 1 mA cm–2 and 1 mAh cm–2, and to 450 h under 5 mA cm–2 and 3 mAh cm–2 at 298 K, which is much longer than the zinc–zinc symmetric cells including the bare ZnSO4 electrolyte (only 95 h at 5 mA cm–2 and 3 mAh cm–2, and 200 h at 1 mA cm–2 and 1 mAh cm–2). Furthermore, β-Ala was found to significantly improve the cycling stability of Zn||Cu asymmetric cells and Zn||V2O5 full cells. This study provides an effective method for engineering electrolytes to inspire rechargeable zinc-ion batteries by selecting ideal natural biomolecules as the electrolyte additives.

Rechargeable lithium metal batteries are among the most versatile platforms for high energy electrochemical energy storage . Unfortunately, uncontrollable growth of lithium dendrite triggers serious safety hazards, low Coulombic efficiency, and short cycling life, impeding the commercial application of lithium metal anode in the advanced energy storage technology , such as lithium-air and lithium‑sulfur (Li S) batteries. Herein, Chitosan oligosaccharide (CSO), an abundant bioderived material was employed to guide uniform lithium deposition and growth. CSO offers three features simultaneously, polar functional groups (-OH and -NH 2 ), natural porous structure , and abundant sources. CSO with a large number of polar groups has strong interactions with Li ions , which could guide the Li ions to form uniform Li deposition. Moreover, the porous structure of CSO could serve as a Li host to accommodate the huge volume change during Li plating and stripping process. Additionally, CSO is a low-cost, abundant, and nontoxic bioderived material, which is suitable for large-scale production of the CSO-Li anode. The proposed strong interactions of CSO with Li ions were confirmed by density functional theory calculations. As expected, the CSO modified electrode demonstrates an outstanding average Coulombic efficiency of over 98% for 600 cycles at a current density of 2 mA cm −2 . And stable cycling performances were achieved in the CSO-Li/CSO-Li symmetrical cells. Moreover, when paired with the LiFePO 4 cathode, Li 4 Ti 5 O 12 anode, high-mass-loading LiNi 0.5 Co 0.2 Mn 0.3 O 2 cathode, and S cathode, the cells using the CSO-Li anodes show the higher capacities and better cycling stabilities compared with those of the cells using the bare Li anodes.

Aqueous zinc-ion batteries are highly praised for their cost-effectiveness, environmental friendliness, and high safety, making them an ideal choice for next-generation energy storage systems. However, the practical application of Zn metal anodes is constrained by well-known challenges such as dendrite growth and significant interfacial side reactions. This study introduces a trace amount of taurine (TAU) as a leveling additive into the electrolyte to optimize the microstructure of the electrolyte and the anode interface chemistry. On one hand, the preferential adsorption of TAU on the Zn surface promotes the in situ formation of a stable, protective molecular interfacial layer on the anode, which helps to refine the deposited grains and guide the uniform deposition of Zn2+. On the other hand, the introduction of TAU can regulate the hydrogen bond structure in the electrolyte, reduce the activity of water, thereby significantly inhibiting the occurrence of side reactions such as hydrogen evolution. Consequently, the Zn//Zn symmetric cell system demonstrates an extended cycle life of over 1150 cycles at a current density of 1 mA cm−2 and maintains stable cycling performance for over 600 cycles at 10 mA cm−2. Moreover, the Zn//Cu asymmetric cell system achieves over 1400 cycles of reversible deposition/dissolution at a current density of 1 mA cm−2, with a coulombic efficiency of 99.4%. The incorporation of TAU further enhances the cycle stability of the Zn//MnO2 full cell. These innovative achievements have laid a solid foundation for the broader industrial adoption of aqueous zinc-ion batteries.

Aqueous zinc ion batteries (AZIBs) have attracted widespread attention due to their unique advantages. However, the growth of dendrites on the anode and the occurrence of side reactions limits the improvement of electrochemical performance of AZIBs. The alloying of zinc anode effectively alleviates above problems, which is beneficial to the long-term cycle performance of AZIBs. In this study, zinc-copper alloy anode (Cu@Zn) was synthesized by melting method. The method is not only simple and easy to operate, but also can make the synthesized anode Cu element uniform distribution and improve the corrosion resistance of the anode. At the same time, the Cu@Zn surface reconstructed has a large proportion of Zn (002) crystal surface exposure, with the zinc affinity of Cu. Both of them can induce the uniform deposition of Zn 2+ ions along the Zn (002) crystal plane, further inhibiting the growth of dendrite. The Cu@Zn//Cu@Zn symmetrical batteries can cycle more than 1000 times at current densities of 0.3 and 1.2 mA cm −2 , and maintain a relatively low hysteresis voltage. And the discharge capacity retention rate of Cu@Zn//MnO 2 maintains 84.64% at 2.0 A g −1 after 1000 cycles. This study provides a new methodological reference for the development of advanced AZIBs anodes. Graphical abstract

Lithium (Li) metal has been considered as an effective anode material because of its high theoretical capacity, but the uncontrolled dendrite growth and the unstable electrode/electrolyte interface limit its practical application. In this work, proanthocyanidin (PA), a natural extracted biomass, was designed and developed as a coating material to guide homogeneous deposition and restrain side reaction for lithium metal batteries. The rigid benzene ring structure of PA can increase the mechanical strength to restrain dendrite growth on Li surface. Moreover, the spontaneous formation of organolithium (PA-Li) structure from the reaction of phenolic hydroxyl group with Li metal increase the ion transportation ability of PA layer and induce the uniform deposition of Li + ions to hinder the growth of Li dendrites, as well as prevent the direct contact of organic electrolyte with Li metal to suppress the interface side reaction. As a result, Li metal anode with PA-Li exhibits stable cycling properties for 2800 h at 2 mA cm -2 and 2 mAh cm -2 , better that of bare Li (200 h). Li-sulfur full battery with PA-Li can still achieve a capacity of 570 mAh g -1 after 300 cycles. This work provides an effective strategy for the construction a natural functional layer on Li surface to enhance the electrochemical performance, as well as the implementation of high-value utilization for natural biomass.

Uniform lithium (Li) deposition and stable interface between anode and electrolyte are crucial factors for realizing the practical application of Li metal anode. Herein, a homogeneous lithium fluoride (LiF) protective layer with many nano slits is constructed on the Li anode by a facile vacuum evaporation method. It can uniformize the Li ion flux at surface of anode via its homogeneity and suppress the violent side reaction between Li and electrolyte via its good compactness. The existence of nano-slits allows the penetration of electrolyte and thus providing sufficient lithium ions transmission channels. Therefore, such a homogeneous LiF layer effectively inhibits the growth of Li dendrites and alleviates the consumption of active Li metal, significantly improving the stability of Li anode during long-term cycles. With the LiF-protected Li anode, the full cell with LiFePO 4 cathode delivers 2.5 times longer lifespan and slower capacity attenuation than control cells. This work highlights significant roles of homogeneous protective layer in stabilizing Li anode and supplies new insights in the design of anode interphase for rechargeable lithium metal batteries (LMBs).

Graphical In this study, a lithiophilic 3D Cu 3 Sn active sites modified commercial Cu foil as current collector is designed by electroplating and heat process, which could induce a uniform nucleation of Li metal. The obtained Li@Cu 3 Sn anode shows superior interface property and efficient Li metal deposition/stripping process. The development of lithium metal battery is severely restricted by its uncontrolled dendrite growth and volume change. In this work, we designed a controllable lithiophilic Cu 3 Sn modified commercial Cu foil as current collector via simple industrial electroplating and heat treatment. As a Li-reservoir substrate for efficient deposition/stripping of Li metal, the introduction of Cu 3 Sn not only increases multiple active sites for the deposition of Li, but also provides more transfer paths for lithium ions. The Li metal anodes prepared by molten Li on the Cu current collector with dispersed Cu 3 Sn active sites provide a uniform lithiophilic surface, which could effectively promote a uniform Li deposition/stripping and suppress the formation of lithium dendrites. As a result, the assembled symmetric battery is stable at a low over-point position for 1600 h without short circuit at 1 mA cm −2 with 1 mAh cm −2 , the full battery paired with LiFePO 4 still maintains a high-capacity retention rate of 97.1 % and a coulombic efficiency (CE) of 99.5 % after 400 cycles at a current density of 2 C. This work provides a facile and controllable strategy for the design of current collectors with high lithium affinity for stable lithium metal anode applications.

Aqueous zinc ion batteries are considered to have a broad application prospect in the future due to their advantages of high safety, low cost, abundant sources, etc. Nevertheless, zinc-ion batteries are limited by their inherent defects of zinc anode, such as uncontrollable dendrite growth and irreversible side reactions. In this work, porous cyclodextrin-based polymers (CD-Si) are successfully constructed and applied as artificial coatings of zinc anode. The porous polymer framework of CD-Si provides abundant zincophilic sites and organized transport channels for zinc-ion transport, thus it could well regulate the uniform deposition of Zn. The Zn anode protected by α -CD-Si exhibited an excellent zinc-ion migration number of 0.92. The assembled α -CD-Si@Zn// α -CD-Si@Zn symmetric battery could achieve a long cycle life of 2000 h at a current density of 0.5 mA cm −2 . Furthermore, the α -CD-Si@Zn//Cu asymmetric battery achieved a low nucleation overpotential of 25 mV. The assembled α -CD-Si@Zn//NH 4 V 4 O 10 full battery was able to cycle stably for 4300 cycles with capacity retention rate of 91 % at a current density of 5 A g −1 . This work provides a satisfactory idea to improve the stability of aqueous zinc ion batteries.
