“…[17a] To further realize a higher CE, recently, Lu et al based on the size effect designed a novel electrolyte beyond the solubility limit by utilizing the ordered nanochannels of 3A zeolite molecular sieve to transfer the highly reactive de-solvation process from the electrode surface to the far-away zeolite molecular sieve (Figure 14a). [51] G2 electrolytes with 1 m NaPF 6 have been proven to achieve 99.9% average CE in Na-Cu cells. [72] However, due to the active chemical nature of the ether groups, the oxidation resistance of ether solvents is relatively poor, making them susceptible to oxidation on the surface of high-voltage positive electrode materials, which limits their range of application.…”

Anode‐free sodium metal batteries (AFSMBs) as one new battery configuration, have attracted more attention in recent years and considered as the promising next‐generation energy storage systems, owing to the advantages of high theoretical energy density, high safety, cost‐saving, and simplified fabrication process. The practical application of AFSMBs, however, is impeded by their poor cycle life arising from the low coulombic efficiency (CE), the growth of metal dendrite, and unstable solid electrolyte interphase (SEI). Recently, some works are reported to dissolve the above‐mentioned issues. In this review, it provides a comprehensive summary of AFSMBs including their origin, mechanism, advantages, challenges, strategies, and perspectives. First, the intrinsic issues of conventional sodium metal batteries are summarized as safety concerns and manufacturing difficulty, which is the background of promoting AFSMBs’ birth. Subsequently, the mechanism, construction requirement, advantages, and challenges of AFSMBs are discussed. Furthermore, the strategies for improving AFSMBs performance in terms of the current collector, electrolyte, and protocols, are summarized based on an extensive literature survey. Finally, the summary and outlook on this emerging field are further discussed briefly.

The lead‐free hybrid perovskite piezoelectrics possess advantages of easy processing, light weight, and low‐toxicity over inorganic ceramics. However, the lack of understanding in structure–property relationships hinders exploration of new molecular piezoelectric crystals with excellent performances. Herein, by introducing chiral α‐phenylethylammonium (α‐PEA+) cations into bismuth‐based hybrid halides, centimeter‐sized (R‐α‐PEA)4Bi2I10 and (S‐α‐PEA)4Bi2I10 single crystals with a superior piezoelectric voltage coefficient g22 of 309 mV m N−1, are obtained. Structural rigidity in crystals leads to a remarkable electrostrictive coefficient Q22 of 25.8 m4 C−2, nearly 20 times higher than that of poly(vinylidene fluoride) (PVDF), which is beneficial to improve piezoelectricity with the synergistic effect of chirality. Moreover, the as‐grown crystals show outstanding phase stability from 173 K to ≈470 K. This work suggests a design strategy based on rigidity and chirality to exploit novel piezoelectrics among hybrid metal halides.
