Li is attractive anode for next-generation high-energy batteries. The high chemical activity, dendrite growth, and huge volume fluctuation of Li hinder its practical application. In this work, a Li–BiOF composite anode (LBOF) is obtained by combining Li metal with BiOF nanoplates through facile folding and mechanical cold rolling. Further, Li 3 Bi/LiF/Li 2 O filler is formed by the in-situ reactions of BiOF with contacted Li. In the filler, the Li 3 Bi, with high ionic conductivity and a lithiophilic nature, provides a mutually permeable channel for Li + diffusion. The low surface diffusion energy barrier of Li 3 Bi and LiF can further promote the uniform deposition of Li. The conductive lithiophilic filler can reduce the local current density and provide a spatial limitation to the deposited Li. Consequently, the symmetrical LBOF||LBOF cell can cycle stably at 1 mA cm −2 for over 1300 h. Additionally, the surface of LBOF is flat with suppressed dendrite formation and free of dead Li accumulation, and the change in electrode volume is significantly alleviated. Furthermore, the LBOF||LiFePO 4 full battery can maintain a stable cycle of more than 200 times with high capacity retention of 88.7% in a corrosive ester-based electrolyte. This simple mechanical approach is compatible with the current industrial route and is inspiring to solve the long-standing lithium-dendrite problem.

Rechargeable aluminum batteries (RABs) are regarded as a promising energy storage system considering the high safety, rich abundance, and high capacity of aluminum. One of the critical challenges for RABs is the dendrite growth of Al, which arouses significant stability and safety issues. In this work, we demonstrate that a graphite coating layer can effectively protect the Al anode against dendrite growth. The Al metal batteries with graphite-coated Al anodes display lower overpotential (43 mV) and better cycling stability (400 h) than those with bare Al. Based on spike-like voltage profiles, metallic Al is found to be preferentially plated on the graphite layer rather than the Al substrate. In addition, the rough graphite coating layer with abundant interspace further regulates the plating/stripping behavior and accommodates the volume change of the Al anode. The dendrite growth of Al is significantly suppressed by graphite coating, which also favors high-performance RABs with a graphite cathode. This study sheds light on the facile and efficient suppression of Al dendrite growth toward RABs.

Notorious lithium dendrite causes severe capacity fade and harsh safety issues of lithium metal batteries, which hinder the practical applications of lithium metal electrodes in higher energy rechargeable batteries. Here, a kind of 3D-cross-linked composite network is successfully employed as a flexible-rigid coupling protective layer on a lithium metal electrode. During the plating/stripping process, the composite protective layer would enable uniform distribution of lithium ions in the adjacent regions of the lithium electrode, resulting in a dendrite-free deposition at a current density of 2 mA cm −2 . The LiNi 0.5 Mn 1.5 O 4 -based lithium metal battery presents an excellent cycling stability at a voltage range of 3.5–5.0 V with the induction of 3D-cross-linked composite protective layer. From an industrial field application of view, thin lithium metal electrodes (40 µm, with 4 times excess lithium) can be used in LiNi 0.5 Mn 1.5 O 4 (with industrially significant loading of 18 mg cm −2 and 2.6 mAh cm −2 )-based lithium metal batteries, which reveals a promising opportunity for practical applicability in high energy lithium metal batteries.

Li metal is regarded as the most promising anode for lithium-based batteries due to its extremely high theoretical capacity and the lowest working potential. However, dendrite caused by uneven Li deposition inhibits its practical application. Here we propose a new concept of utilizing amorphous metallic nucleation seeds to induce the uniform deposition of Li. Amorphous 3 °C liquid metal coated on MXene framework is selected as an example for deep investigation. The results indicate that amorphous liquid metal nucleation seeds are stable against MXene and can induce isotropic nucleation and uniform growth of Li. The Coulombic efficiency and performance of symmetric cells are obviously improved both in ether-based and carbonate-based electrolyte under the regulation of amorphous liquid metal seeds. Full lithium metal cells with LiFePO 4 and crumpled MXene nanosheet encapsulated LiMn 2 O 4 cathodes also exhibit better electrochemical performance after modification. Additionally, the concept may be useful for developing other metal based anodes.

It is so far an efficient way for depressing dendrite growth to adjust the electrolyte composition . Therefore, we study the electrochemical behavior of lithium metal electrodeposited in a LiPF 6 -propylene carbonate (PC) electrolyte by adding two kinds of crown ether . The effect of crown ether concentration on the Coulombic efficiency of lithium electrodes has be evaluated, and the electrodeposition behavior of lithium metal on negative electrode has be analyzed by cyclic voltammetric curve, electrodeposition curve and lithium metal deposition morphology. The results show that a certain amount of crown ether (15-crown-5 and 12-crown-4) can preferentially coordinate with lithium ion in the electrolyte and form complex compounds, which reduce the lithium ions concentration in the “hot spot” and level the lithium electrode greatly by inhibiting the preferential growth of lithium dendrite . A uniform and dense nano-columnar lithium layer could be obtained at the current density of 2.0 mA cm −2 when the deposition amount is 1.0 mAh cm −2 , and the concentration of 15-crown-5 and 12-crown-4 ether are 0.3 M and 0.2 M, respectively. Gaussian calculation results show that the lithium-crown complex has a relatively lower lowest unoccupied molecular orbit (LUMO), where electrons could be injected during the charging process, leading to decreased Coulumbic efficiency.

Aqueous zinc ion batteries (AZIBs) are promising electrochemical energy storage devices due to their high theoretical specific capacity, low cost, and environmental friendliness. However, uncontrolled dendrite growth poses a serious threat to the reversibility of Zn plating/stripping, which impacts the stability of batteries. Therefore, controlling the disordered dendrite growth remains a considerable challenge in the development of AZIBs. Herein, a ZIF-8-derived ZnO/C/N composite (ZOCC) interface layer was constructed on the surface of the Zn anode. The homogeneous distribution of zincophilic ZnO and the N element in the ZOCC facilitates directional Zn deposition on the (002) crystal plane. Moreover, the conductive skeleton with a microporous structure accelerates Zn2+transport kinetics, resulting in a reduction in polarization. As a result, the stability and electrochemical properties of AZIBs are improved. Specifically, the ZOCC@Zn symmetric cell sustains over 1150 h at 0.5 mA cm−2with 0.25 mA h cm−2, while the ZOCC@Zn half-cell achieves an outstanding Coulombic efficiency of 99.79% over 2000 cycles. This work provides a simple and effective strategy for improving the lifespan of AZIBs.Keywords:aqueous zinc ion batteries;MOFs;anode;dendrite growth

Naturally structural and chemical interface instability between solid-state electrolyte (SSE) and Li anode is still a bottleneck for the suppression of Li dendrites to date. Herein, we design the 3D in situ -fluorinated perovskite-type electrolyte hybridized with poly (ethylene oxide) fibers (F-LLTO@PEO) for the synergistically enhanced physicochemical-interface stability. The rapidly Li-ions-transporting and high shear modulus 3D skeleton-structured SSE can physically suppress Li dendrite growth, while the LiF-rich solid-state electrolyte interface (SEI) layer of the in situ fluoridated SSE can chemically eliminate the security risk of Li dendrites. This unique SSE exhibits a high ionic conductivity of 5 × 10 −4 S cm −1 at 25°C. Based on the above, the as-developed solid-state lithium metal batteries (SSLMBs) possess excellent rate-capability of 95 mAh g −1 @ 5 C and cycling stability over 80% after 100 cycles at 90°C. Evidently, this physicochemically dendrite-suppressed strategy will open a previously unexplored opportunity in developing safe, high-performance SSLMBs.

Li metal is the next-generation anode material for high-energy-density Li-ion batteries. Unfortunately, its practical application is hampered by drawbacks such as an unstable solid electrolyte interphase and undesirable Li dendrites. Herein, an Fe-based protective layer with a valence gradient is constructed on Li anodes, which consists of an Fe 3+ /Fe 2+ -rich outer layer and an Fe 0 -containing inner layer. The protective layer not only isolates the underlying Li metal from the corrosive carbonate electrolyte, but also uniformly stores Li during plating and inhibits the growth of Li dendrites. The Li anode with the Fe-based protective layer shows dendrite-free Li plating/stripping behaviors; therefore, Li symmetric cells stably run for 1000 h at 1 mA cm -2 and 1 mA h cm -2 and even survive for 380 h at an ultra-high capacity of 30 mA h cm -2 . With such a highly stable Li anode, LiFePO 4 cells operate steadily for 1600 and 1000 cycles at 1 and 5 C, respectively. High-loading LiCoO 2 cells also present excellent cycling stability and rate capability, proving the advantages of the protective layer in Li anode protection.

The metallic lithium (Li) is considered as the most promising anode material for high-energy batteries. Nevertheless, the uncontrollable growth of Li dendrite and unstable electrolyte/electrode interface still hinder the development of Li-based battery. In this work, a novel strategy has been proposed to stabilize Li anode by in-situ polymerizing polypyrrole (PPy) layer on Ni foam (PPy@Ni foam) as an artificial protective layer. The PPy protective layer can effectively decrease the contact between Li metal and electrolyte during cycling. In addition, the morphology characterization shows that the PPy layer can help the even Li deposition underneath the layer, leading to a dendrite-free Li anode. As a result, when deposited 2 mAh•cm −2 Li metal, the PPy@Ni foam can keep stable Coulombic efficiency (99%) during nearly 250 cycles, much better than the pure Ni foam (100 cycles). Even in the case of the Li capacity of 10 mAh•cm −2 , the stable cycling performance for 60 cycles can still be achieved. Furthermore, when assembled with LiFePO 4 material as the cathode for a full cell, the PPy@Ni foam can keep high capacity retention of 85.5% at 500 cycles. In our work, we provide a simple and effective method to enhance the electrochemical performances of Li metal-based batteries, and reveal a new avenue to design three-dimensional (3D) metallic current collector for protecting the Li metal anode.

Lithium metal is the Holy Grail anode material for high-energy-density batteries. Unfortunately, applications of Li metal anodes are restricted by their inherent propensity to form dendrites at practical current densities. Here we present an approach that directly converts commercial polycrystalline Li (poly-Li) into various monocrystalline Li metal anodes with single facets via a recrystallization technique. By elucidating the diffusive kinetic and mechanical characteristics of different Li facets, we reveal that monocrystalline Li(110) exhibits the lowest diffusion barrier of 0.02 eV, an order of magnitude lower than poly-Li’s 0.2 eV, and a 71% reduction in Young’s modulus from 9.42 GPa to 2.71 GPa. The critical current density can be raised by an order of magnitude in solid-state batteries using monocrystalline Li(110), and the cycling stability of Li metal batteries is extended fivefold. We envision that the manipulation of the crystal plane will effectively tackle the pivotal challenges in achieving high-energy-density batteries.

Optimizing Zn 2+ dispersion and regulating Zn 2+ deposition is a key issue in the aqueous Zn-ion anodes. Herein, the flexible membrane (CNT/PAN/Ag) with uniformly interwoven pores was facilely fabricated by one-step phase inversion method. The complex woven pore structure can effectively disperse the flow of Zn 2+ , reduce current density of nucleation sites, and avoid the aggregated deposition of Zn 2+ . Furthermore, the scalable Janus membrane with different affinities to electrolyte on the two sides can be designed based on the membrane surface structure. The high wettability of the upper surface of the membrane with electrolyte facilitates rapid transfer of Zn 2+ flux into the membrane for redispersion, and low wettability of the back surface is benefit to isolate electrolyte from surface of the zinc anode and to avoid side reactions brought about by the aqueous electrolyte. Meanwhile, by virtue of the high adsorption energy with Zn 2+ , the doped Ag active sites in the membrane further extend the dispersion path of Zn 2+ within the membrane and induce portion of Zn 2+ to be deposited within the membrane, balancing and reducing current density at the deposition interface. In the galvanostatic current test of the symmetric battery at 1 mA cm −2 , 0.5 mAh cm −2 , the battery can be stably cycled more than 1000 h, the specific capacity of pouch cell with NH 4 V 4 O 10 reserved 384 mA h/g at 5 Ag −1 after 95 cycles. The work presents a new flexible membrane design for solving the Zn dendrites in aqueous zinc ion batteries.
