“…As the scanning rate increases, the reaction deviates more from the equilibrium state, resulting in an increase in overpotential, which shifts the oxidation peak to a positive potential. The relationship between scan rate and current density could be determined by the power-law as follows: − in which b = 1 and 0.5 indicate a capacitance- and diffusion-controlled process of electrode. As we can see from Figure b, the obtained b value is 0.889, indicating that storing Na + in PL-600 is dominated by capacitive process.…”

Nitrogen doping carbon materials are considered to be promising candidates for Na+ storage anodes. However, hitherto, the effects and mechanism of specific single N configuration (among pyrrolic N, quaternary N, and pyridinic N), on the sodium storage behaviors of carbon materials, are still puzzling, owing to the difficulties in accurately synthesizing a certain type of single N configuration dominated carbon materials (NCDCMs). Here, various NCDCMs have been successfully controlled and synthesized by small molecule polymerization methods, and their synthesis process has been also verified by NMR, MOLDI-TOF, TG-MS, etc. When serving as sodium ion battery anodes, the NCDCMs dominated by a high concentration of pyrrolic N (>80.3%) exhibits a satisfactory reversible capacity (434.5 mA h g–1 at 50 mA g–1 and 146.7 mA h g–1 at 2000 mA g–1, respectively). It is revealed that pyrrolic N has more suitable adsorption energy and larger interlayer spacing, by density functional theory calculations and electron orbital theory, respectively, which synergistically makes the material obtain excellent electrochemical performance. This research exhibits a more efficient way to reveal the differences in the sodium ions storage behavior of different nitrogen configurations doped carbon, and provides new insight for the precise design and synthesis of a certain type of heteroatom doping to achieve satisfactory electrochemical performance.

[117] Similar strategies include the formation of the polymer layer, [113,118] metal oxide, [59,119] AlF 3 , [120] and other carbonaceous materials [121] as interlayers between NaSICON electrolyte and Na metal were found to improve the wetting and compatibility of NaSICON electrolyte with metallic Na.…”

A surge of interest has been brought to all-solid-state batteries (ASSBs) as they show great prospects for enabling higher energy density and improved safety compared to conventional liquid batteries. Na Super Ionic CONductors (NaSICONs) proposed by Goodenough and Hong in 1976 are the most promising materials class for Nabased ASSBs owing to their excellent ion conductivity (>1 mS cm −1 ), high thermal and chemical/electrochemical stability, as well as good chemical/electrochemical compatibility with electrode materials. The major challenge facing NaSICONtype electrolytes is the generally high interfacial resistance and thus sluggish charge transfer kinetics across the NaSICON/cathode interface. Great endeavors in the past few years have led to progress in the improvement of the ion-conducting property, and a dramatic decrease in the NaSICON/electrode interface resistance. Excellent cycling performance and rate capability have been achieved through interface engineering. In this review article, we summarize the state-of-theart findings for various derivatives of NaSICON structured solid electrolytes, with the aim of providing a deeper understanding of the underlying mechanism for the improvement of ion conductivity, and the intrinsic reasons for the enhanced interface charge transfer kinetics. These strategies can be readily extended to other solid electrolytes. We hope this review will inspire more work on NaSICONtype solid electrolytes and solid-state batteries.

“…The strategy (2) involves multiple methods, including the implementation of Na-based composite anodes [42], surface coatings (i.e., Sn, TiO 2 , AlF 3 , PVDF, etc.) [13,14,[43][44][45][46][47], and bulk doping of NZSP [48][49][50]. Zhou et al demonstrated that heating NZSP over 300 • C results in the in situ formation of a thin interfacial interlayer with good molten Na wettability (Figure 2a,b) [41].…”

“…In recent years, all-solid-state SMBs have received considerable interest due to their attractive safety from the use of nonflammable and thermally stable solid electrolytes (SE), and potentially high energy density from the use of Na metal anodes and high-voltage cathodes [2,[9][10][11][12]. However, they suffer from the same or even more severe Na|SE wetting issues since they are supposed to run at room or ambient temperatures below the melting point of Na at 98 • C. The poor Na|SE contact will lead to large interfacial resistances and inhomogeneous Na stripping/plating morphologies, resulting in dendrite growth and eventually cell short circuits [13][14][15]. To tackle this issue, wetting-enhancement-based therapies have been extended from molten SMBs to all-solid-state SMBs.…”

This review focuses on the Na wetting challenges and relevant strategies regarding stabilizing sodium-metal anodes in sodium-metal batteries (SMBs). The Na anode is the essential component of three key energy storage systems, including molten SMBs (i.e., intermediate-temperature Na-S and ZEBRA batteries), all-solid-state SMBs, and conventional SMBs using liquid electrolytes. We begin with a general description of issues encountered by different SMB systems and point out the common challenge in Na wetting. We detail the emerging strategies of improving Na wettability and stabilizing Na metal anodes for the three types of batteries, with the emphasis on discussing various types of tactics developed for SMBs using liquid electrolytes. We conclude with a discussion of the overlooked yet critical aspects (Na metal utilization, N/P ratio, critical current density, etc.) in the existing strategies for an individual battery system and propose promising areas (anolyte incorporation and catholyte modifications for lower-temperature molten SMBs, cell evaluation under practically relevant current density and areal capacity, etc.) that we believe to be the most urgent for further pursuit. Comprehensive investigations combining complementary post-mortem, in situ, and operando analyses to elucidate cell-level structure-performance relations are advocated.
