The nucleation and growth of Li metal during deposition and the associated dendrite penetration are the critical and fundamental issues influencing the safety and power density of solid-state lithium metal batteries (SSLBs). However, investigations on Li metal deposition/dissolution especially the formation and growth of Li dendrites and their determining factors in the all-solid-state electrochemical systems are still lacking. In this work, in situ observations of the Li metal growth process, and defects induced heterogeneous deposition under cathodic load, are reported. By exploiting in situ scanning electron microscopy, along with electrochemical analytical approaches, the spatial distribution and morphological evolution of the deposited Li at the electrode|solid electrolyte interface are obtained and discussed. This investigation reveals that the formation of lithium whiskers is decided by the local Li ion flux and the deposition active sites, which are closely dependent on the content and types of defects in the polycrystalline electrolyte. Moreover, the defect regions exhibit faster Li deposition kinetics and higher nucleation tendency. These results can advance the fundamental understanding of the Li penetration mechanism in SSLBs.

Rechargeable aluminum ion batteries (RAIBs) exhibit great potential for next-generation energy storage systems owing to the abundant resources, high theoretical volumetric capacity and light weight of the Al metal anode. However, the development of RAIBs based on Al metal anodes faces challenges such as dendrite formation, self-corrosion, and volume expansion at the anode/electrolyte interface, which needs the rational design of an aluminum anode for high-performance RAIBs. This work proposes a novel and low-cost strategy by utilizing an alloy electrodeposition method in a low-temperature molten salt system to fabricate an aluminum–tin (AlSn) alloy coating layer on copper foil as the anode for RAIBs, which successfully addresses the issues of dendrite formation and corrosion at the anode/electrolyte interface. The artificial AlSn alloy layer could enhance the active sites for metal Al homogeneous deposition and effectively retard the dendrite formation, which was verified by an in situ optical microscopy study. The symmetric AlSn@Cu cell demonstrates a low average overpotential of ∼38 mV at a current density of 0.5 mA cm−2 and a long-term lifespan of over 1100 h. Moreover, the AlSn@Cu//Mo6S8 full cells deliver a high capacity of 114.9 mA h g−1 at a current density of 100 mA g−1 and maintain ultra-stable cycling stability even over 1400 cycles with a ∼100% coulombic efficiency (CE) during the long-term charge/discharge processes. This facile alloy electrodeposition approach for designing high-performance Al-based anodes provides insights into the understanding of artificial interface chemistry on Al-based anodes and potentially accelerates the design of high-performance RAIBs.

Among all energy storage systems, lithium metal batteries (LMBs) show great advantages in terms of energy density. Nevertheless, the challenges of lithium metal anodes, namely, dendrite formation and low Coulombic efficiency, hinder the practical application of LMBs. In this work, we used the ZnO/carbon shell/carbon cloth as a host for the lithium metal anode. The introduction of ZnO sites reduces the nucleation barrier of lithium deposition, and the existence of a 3D current collector alleviates the volume change during lithium plating/stripping. In addition, the combination of ZnO/C and 3D carbon cloth decreases the local current density and contributes to uniform lithium plating/stripping. The half cells assembled with modified carbon cloth electrodes cycle for more than 125 cycles with a high Coulombic efficiency of 99.34%, even under a high areal capacity of 6 mA h cm–2. By and large, our work provides a simple and effective strategy to modify the current collector for high Li-content anodes.

The coupling effect of adipic acid and NaCl on electrochemical migration (ECM) of SAC305 solder alloy for printed circuit boards was studied using a self-designed high-throughput preparation and electrochemical test platform. The promotion effect of 1000 ppm NaCl on anodic dissolution and ion migration steps in the electrochemical migration substantially increased the dendrite formation probability ( P dendrite ) of SAC305 solder alloy. The low P dendrite in 1000 ppm adipic acid was attributed to the enhanced resistance to ion migration step by the formation of complex precipitates. Adding 1 ppm adipic acid into 1000 ppm NaCl could effectively decrease P dendrite due to the co-formation of hydroxide and complex precipitates, while increasing adipic acid concentration (from 10 ppm to 1000 ppm) instead raised P dendrite because hydroxide precipitates could transform into dendrite source at the cathode.

Alkaline zinc-iron flow batteries (ZFBs) have recently attracted renewed attention. However, the critical issues with zinc anodes, such as dendrite formation, side reactions, and labile plating or stripping, have yet to be adequately addressed. Here, an attempt is made to overcome these challenges by designing Boron-doped carbon-felt (B–CF) electrodes rich in electron-deficient sites and defects. The fabricated B–CF provides improved adsorption of negatively charged Zn(OH) 4 2− , robust Zn nucleation sites, and lower Zn nucleation and deposition overpotentials, leading to homogeneous Zn deposition morphology. Uniform Zn deposition enables the prevention of undesirable dendrite growth and parasitic reactions. As a result, the constructed alkaline ZFBs achieve a high average Coulombic efficiency of ≈99.85% and energy efficiency of 88% with uniform Zn deposition during 300 cycles (40 mA cm −2 ). This work expands the understanding of the electrode design strategy for achieving favorable Zn plating/stripping.

Although aqueous zinc metal batteries (AZMBs) have attractive advantages such as high safety, low cost and eco-friendliness, severe dendrites formation and side reactions of zinc metal anodes cause a serious challenge for commercial applications. Herein, a polyanionic hydrogel electrolyte, poly 2-acrylamido-2-methyl-1-propane sulfonate zinc (PAMPSZn) is firstly designed and synthesized by ion exchange and free-radical polymerization. The PAMPSZn hydrogel electrolyte owns fixed polyanionic chain and restricted Zn 2+ transport channels, which can effectively alleviate the side reactions and prevent the formation of Zn dendrites simultaneously. Consequently, the anode-friendly electrolyte not only enables ultra-stable Zn plating/stripping over 4500 h at 1.0 mA cm −2 , but also achieves high preferred orientation deposition during the procedure of repeated plating/stripping. It delivers high reversibility with high initial coulombic efficiency (87.5%) and average coulombic efficiency (99.3%) in Zn/Cu cells at 0.5 mA cm −2 . Zn/V 2 O 5 cells with the developed electrolyte also possess outstanding cycle stability with capacity retention of 80.2% after 400 cycles at 0.5 A g −1 . The PAMPSZn hydrogel electrolyte with unique fixed polyanionic chain and restricted Zn 2+ transport channels demonstrates an effective strategy to solve both dendrites formation and side reactions in AZMBs, providing a new opportunity for high performance AZMBs.

Ta-doped Li6.4La3Zr1.4Ta0.6O12 (LLZTO) for solid-state lithium batteries demonstrates encouraging performance; however, they encounter issues with lithium dendrite formation that impede their widespread use. Herein, we design a LLZTO ceramic with an interlayer containing a mixed dense layer of Ag and LLZTO, prepared by one-step sintering. The Ag-rich interlayer in LLZTO can hinder the growth and the penetration of lithium dendrites though the reaction between Ag and lithium metal. Compared with the Ag-free counterpart, a higher critical current density of 0.6 mA cm–2, in addition to a longer life span under a current density of 0.2 mA cm–2, is achieved by adopting the interlayer in LLZTO. This research offers novel insights into the engineering of garnet-based solid electrolytes, tailored for the advancement of high-rate lithium metal batteries.

KTiOPO 4 (KTP) microblocks, which were prepared using a simple solid state method, have been used as novel anode materials for sodium ion batteries (SIBs). The as-prepared KTP microblocks with size distribution of 300–500 nm delivered high performance of electrochemical storage of sodium, such as an initial charge capacity of 108.7 mAh g −1 at 200 mA g −1 with almost no capacity loss in 1000 cycles, and good rate capability of 80.3 mAh g −1 even at the current density of 1000 mA g −1 . Ex situ XPS and in situ XRD showed an irreversible phase reaction mechanism during the insertion/extraction of Na + . Dendrite formation at lower potential could be suppressed at the average potential of 1.3 V. This work indicated that KTP microblocks are low-cost and safe anode materials for SIBs.

The performance of aqueous zinc-ion batteries is frequently hindered by anode-related issues such as uncontrolled dendrite formation and side reactions. Metal–organic frameworks (MOFs), characterized by their highly ordered porous structures, remarkably large specific surface areas, and tunable active sites, offer a promising solution by regulating Zn2+ flux and promoting uniform Zn deposition. In this study, a Cu-MOF was synthesized in situ on carbon cloth (CM-C) and functioned as an ion-buffering layer within the battery. This innovative configuration significantly mitigates side reactions, achieving an extended cycle life of nearly 800 h at a high current density of 10.0 mA cm–2 (areal capacity: 10.0 mA h cm–2) and nearly 1200 h at 5.0 mA cm–2. After 2000 cycles at 5.0 mA cm–2, the battery demonstrated an average Coulombic efficiency of 99.3%. Additionally, the full battery containing CM-C demonstrated enhanced capacity and stability. This simple and novel structure provides new possibilities for enhancing the cycling stability of zinc-ion batteries.

Anode-free lithium batteries without lithium metal excess are a practical option to maximize the energy content beyond the conventional design of Li-ion and Li metal batteries. However, their performance and reliability are still limited by using low-capacity oxygen-releasing intercalation cathodes and flammable liquid electrolytes. Herein, we propose quasi-solid-state anode-free batteries containing lithium sulfide-based cathodes and non-flammable polymeric gel electrolytes. Such batteries exhibit an energy density of 1323 Wh L −1 at the pouch cell level. Moreover, the lithium sulfide-based anode-free cell chemistry endows intrinsic safety thanks to a lack of uncontrolled exothermic reactions of reactive oxygen and excess Li inventory. Furthermore, the non-flammable gel electrolyte, developed from MXene-doped fluorinated polymer, inhibits polysulfide shuttling, hinders Li dendrite formation and further secures cell safety. Finally, we demonstrate the improved cell safety against mechanical, electrical and thermal abuses.

Aqueous zinc-ion batteries (AZIBs) have recently been paid great attention due to their robust safety features, high theoretical capacity, and eco-friendliness, yet their practical application is hindered by the serious dendrite formation and side reactions of Zn metal anode during cycling. Herein, a low-cost small molecule, nicotinamide (NIC), is proposed as an electrolyte additive to effectively regulate the Zn interface, achieving a highly reversible and stable zinc anode without dendrites. NIC molecules not only modify the Zn 2+ solvation structure but also preferentially adsorb on the Zn surface than solvated H 2 O to protect the Zn anode and provide numerous nucleation sites for Zn 2+ to homogenize Zn deposition. Consequently, the addition of 1 wt% NIC enables Zn||Zn symmetric cells an ultra-long lifespan of over 9700 h at 1 mA cm −2 , which expands nearly 808 times compared to that without NIC. The advantages of NIC additives are further demonstrated in NaVO||Zn full cells, which exhibit exceptional capacity retention of 90.3 % after 1000 cycles with a high Coulombic efficiency of 99.9 % at 1 A/g, while the cell operates for only 42 cycles without NIC additive. This strategy presents a promising approach to solving the anode problem, fostering advancements in practical AZIBs.

Lithium metal stands out as an exceptionally promising anode material, boasting an extraordinarily high theoretical capacity and impressive energy density. Despite these advantageous characters, the issues of dendrite formation and volume expansion of lithium metal anodes lead to performance decay and safety concerns, significantly impeding their advancement towards widespread commercial viability. Herein, a lithium-rich Li-B-In composite anode with abundant lithophilic sites and outstanding structural stability is reported to address the mentioned challenges. The evenly distributed Li-In alloy in the bulk phase of anodes act as mixed ion/electron conductors and nucleation sites, facilitating accelerated Li ions transport dynamics and suppressing lithium dendrite formation. Additionally, these micron-sized Li-In particles in LiB fibers framework can enhance overall structural integrity and provide sufficient interior space to accommodate the volume changes during cycling. The electrochemical performance of Li-B-In composite anode exhibits long-term cyclability, superior rate performance and high-capacity retention. This work confirms that the synergy between a 3D skeleton and hetero-metallic lithiophilic sites can achieve stable and durable lithium metal anodes, offering innovative insights for the practical deployment of lithium metal batteries.
