Sodium (Na) metal is considered as the promising anode for next‐generation high‐energy‐density Na‐metal batteries owing to its highest specific capacity and lowest electrochemical potential among all Na‐based anode candidates. However, the Na metal anode suffers from considerable volume change, nonuniform Na deposition, and an unstable electrode–electrolyte interface, which result in rapid capacity fade and poor cycling stability, hampering its practical application. To tackle aforementioned issues, many strategies have been developed to accommodate and guide Na nucleation/growth as well as stabilize the interface, including structure stabilization by applying 3D host materials, electrolyte modification and interface engineering to form stable interfaces and guide the Na deposition, etc. The present review is intended as a guideline through the fundamental challenges affecting the performance of Na metal anodes along with corresponding mitigation strategies. Moreover, the specific mechanisms for stabilizing Na metal anodes are discussed in detail. Apart from the stabilization of the Na metal anode in contact with liquid electrolytes, attention has also been paid to the review of stabilization of the Na metal anode in contact with solid‐state electrolytes. Furthermore, unresolved challenges and promising perspectives for stable Na metal anodes in practical applications are presented.

“…After full cell performance tests, a flexible pouch cell was assembled to explore the adaptability and practical application of the separator. Non-Newtonian fluid state NaK@Super P (NaK@C) was used as the anode, [37,38] PPB as the cathode, and 0.8 m KPF 6 in EC:DEC = 1:1 as the electrolyte (Figure S27, Supporting Information). The anode and cathode of the soft pack battery are obtained by cutting Cu and Al in one piece, respectively, which can effectively reduce the difficulty of sealing.…”

Separators with low-cost, superior mechanical properties, such as nanofiber materials, are considered a viable option for solving the dendritic problem in alkali metal batteries. Consuming the dendrites rather than blocking them underpins the long-life stable cycle performance of the cell. Herein, a five-layer structural separator (LiNO 3 @PVDF@mask) is presented, in which a mask is used as a framework and the polyvinylidene fluoride (PVDF) layer loaded with LiNO 3 can generate a passivation layer by reacting with K dendrites. In the case of potassium metal batteries, for example, the LiNO 3 @PVDF@mask separator has excellent mechanical properties that can effectively cope with the hazards caused by the K dendrite. In addition, sustained-release LiNO 3 can react with penetrated K dendrites to form inactive substances like KNO 3 and K 2 O, blocking further dendrite growth. Importantly, the LiNO 3 @PVDF@mask separator uses a low-cost abundant mask and possesses excellent wettability of electrolyte with a reduced amount of liquid electrolyte, enabling one to further iron out cost problems. This study opens up a new direction for research and contributes to practical applications of flexible devices for rechargeable alkaline metal batteries.

“…[ 1–8 ] Sodium metal battery has gotten extensive attention owing to its advantages of low cost, abundant sodium resources, high theoretical specific capacity of 1166 mAh g −1 as well as low potential (−2.71 V vs SHE). [ 9–14 ] Nonetheless, there are many grave problems to be solved before acquiring a stable sodium metal anode, including (i) inhomogeneous Na + flux deposition leading to the propagation of Na dendrites, [ 15–18 ] (ii) Na dendrites piercing the fragile solid electrolyte interphase (SEI), resulting in the risk of short‐circuit even explosion for Na ion battery, [ 19–21 ] and (iii) the volume expansion of Na anode accelerating the fraction of SEI. [ 22,23 ] These hazards would result in a short‐life Na anode.…”

Sodium metal battery is supposed to be a propitious technology for high‐energy storage application owing to the advantages of natural abundance and low cost. Unfortunately, the uncontrollable dendrite growth critically hampers its practical implementation. Herein, an inorganic/organic hybrid layer of NaF/CF/CC on the surface of Na foil (IOHL‐Na) is designed and synthesized through the in situ reaction of polyvinylidene fluoride (PVDF) and metallic sodium. This protective layer possesses satisfactory Young's modulus, good kinetic property, and sodiophilicity, which can distinctly stabilize Na metal anode. As a result, the symmetric IOHL‐Na cell achieves a lifespan of 770 h at 1 mAh cm−2/1 mA cm−2 in carbonate electrolyte. The assembled full battery of IOHL‐Na||Na3V2(PO4)3 delivers a high discharge capacity of 85 mAh g−1 at 10 C after 600 cycles under ambient temperature. Furthermore, the IOHL‐Na||Na3V2(PO4)3 cell still can steadily operate at 10 C for 600 cycles at 55 °C. And when testing at an ultralow temperature of −40 °C, the full cell achieves 40 mAh g−1 at 0.5 C with a prolonged lifespan of 450 cycles. This work offers a new approach to protect the metal sodium anode without dendrite growth under wide temperatures.
