“…[ 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.

Conventional additives are mostly used as sacrificial additives to reinforce the SEI layer, whereas APFA mainly modulates the lithium deposition behavior by improving the electron transfer step kinetics through the adsorption of PFA − anions on the lithium surface.…”

Lithium metal anodes possess ultrahigh theoretical specific capacity for next-generation lithium metal batteries, but the infinite volume expansion and the growth of lithium dendrites remain a huge obstacle to their commercialization. Therefore, here, we construct a CuO-loaded 3D polyethersulfone (PES) nanofiber frame onto a lithiophilic Cu 2 O/Cu substrate to promote the lithium storage performance of the composite anode, and the 3D frame can effectively alleviate the volume expansion of lithium (Li) metal anodes. Meanwhile, lithium reacts with CuO in the composite nanofiber and Cu 2 O of the substrate to generate Li 2 O, which can strengthen the solid electrolyte interface (SEI) layer and achieve the uniform deposition of lithium. In addition, the combination of the heat treatment method and electrospinning technology solves the problem of poor adhesion between the fiber film and the substrate. As a result, the PES/CuO−Cu 2 O (PCC) composite current collector still maintains a smooth and flat lithium-depositing layer at 5 mA cm −2 . The PCC-assembled Li||Cu halfcell can operate stably for 320 cycles at 0.5 mA cm −2 , which is about 4 times that of bare Cu. Furthermore, symmetrical batteries with PCC@Li can maintain excellent cycle stability for 1770 h. Accordingly, this work provides a low-cost and highly effective strategy for stabilizing the lithium metal anode.
