Sodium metal is one of the most promising anodes for the prospective low-cost rechargeable batteries. Nevertheless, the commercialization of Na metal anodes remains restricted by sodium dendrite growth. Herein, halloysite nanotubes (HNTs) were chosen as the insulated scaffolds, and Ag nanoparticles were introduced as sodiophilic sites to achieve uniform sodium deposition from bottom to top under the synergistic effect. Density functional theory (DFT) calculation results demonstrated that the presence of Ag greatly increased the binding energy of sodium on HNTs/Ag (−2.85 eV) vs HNTs (−0.85 eV). Meanwhile, thanks to the opposite charges on the inner and outer surfaces of HNTs, faster Na+ transfer kinetics and selective adsorption of SO3CF3 – on the inner surface of HNTs were achieved, thus avoiding the formation of space charge. Accordingly, the coordination between HNTs and Ag afforded a high Coulombic efficiency (about 99.6% at 2 mA cm–2), long lifespan in a symmetric battery (for over 3500 h at 1 mA cm–2), and remarkable cycle stability in Na metal full batteries. This work offers a novel strategy to design a sodiophilic scaffold by nanoclay for dendrite-free Na metal anodes.

“…In comparison, polymer electrolytes are more suitable for mass applications because of their easy operation, excellent flexibility, and good interface contact with electrodes. Nevertheless, there are still some knotty issues restraining the application of the polymer electrolytes, such as poor ionic conductivity, relatively narrow voltage windows, poor interfacial stability, and low mechanical strength. − …”

The safety issue of lithium batteries based on liquid electrolytes has become the focus of attention, especially when the batteries are exposed to mechanical, thermal, or electrical abuse conditions. To address this issue, gel polymer electrolytes (GPEs) have attracted widespread interest due to the property of solid–liquid coexistence with higher ionic conductivity, flexibility, and safety. In this work, a poly(vinylidene-fluoride-co-hexafluoropropylene) (PVDF-HFP)/poly(methyl methacrylate) (PMMA) matrix GPE, containing bis(trifluoromethane)sulfonimide lithium salt (LiTFSI) and spherical zirconium dioxide (ZrO2) nanoparticles, is successfully designed and synthesized by a simple one-step solution-casting route. It has been found that the obtained PVDF-HFP/PMMA-ZrO2-6% (PPZ-6%) electrolyte film possesses an excellent tensile strength of 37.7 MPa. Moreover, the PPZ-6% GPE not only has a high ionic conductivity of 1.46 × 10–3 S cm–1 at 25 °C but also presents excellent interface compatibility in an Li||Li symmetrical battery. The LiFePO4||Li cell assembled with the PPZ-6% GPE exhibits good cyclic stability at room temperature, e.g., a high discharge specific capacity of 153.0 mAh g–1, and a high Coulombic efficiency of 99% after 200 cycles at 0.5 C. Therefore, this organic–inorganic hybrid GPE modified with spherical ZrO2 nanoparticles reveals a good application prospect for high-performance lithium metal batteries (LMBs).

Solid polymer electrolytes (SPEs) are considered to be an important move to revive high-energy-density lithium-metal batteries due to their good flexibility and high safety. However, the low room-temperature ionic conductivity of SPEs has always been a stumbling block for their practical applications. Herein, a composite SPE has been fabricated by the cooperation of polyethylene oxide (PEO) and a type of natural nanoclay-halloysite nanotube (HNT) in a poly(vinylidene fluoride) (PVDF) matrix. It is expected that the sticky PEO can improve the interfacial stability of the SPE and lithium foil, while the special structure and surface charge properties of the HNTs changed the coordination environment of lithium ions and facilitated Li + running on highways along the HNT outer surface. The optimized SPE composite showed an outstanding roomtemperature ionic conductivity of 2.45 × 10 −4 S cm −1 and high ion transference number of 0.67 at 25 °C. A LiFePO 4 /SPE-H5/Li full battery retained a discharge capacity of 142 mAh g −1 after 200 cycles at a rate of 0.2 C (25 °C). In addition, SPE-H5 can also be used in a 4.3 V high voltage NCM/SPE-H5/Li battery due to its excellent electrochemical stability window (more than 5 V). This work also reveals that lower-cost natural clay minerals are excellent nanoceramic fillers in realizing sustainable high-energy-density energy storage.
