“…Unlike Au|NASICON|Au cells, in the low‐frequency range, a semicircle was observed for Na symmetrical cells with a capacitance of 3 × 10 −8 F (measured at a frequency of 1.7 kHz) that can be assigned to charge transfer resistance ( R CT ). [ 17 ] Hence the total resistance ( R T ) of the cell is the summation of R CT and R Electrolyte (resistance of grain and grain boundary, Figure 2c). As with Au electrodes negligible Na + ‐ion charge transfer will occur between the electrode and the electrolyte, the values obtained show only the impedance of the SSE without any interface contribution.…”

“…[ 14 ] Thermal treatments and removing surface contaminations have also decreased the interfacial resistance to even lower values (≈10 Ω cm 2 ). [ 17 ] Overall, such approaches ensured satisfactory performances of the solid state batteries (SSBs). However, introducing interlayers and high‐temperature heating steps can increase the cost and complicate the synthesis process.…”

Ceramic Na superionic conductor (NASICON)‐type Na3Zr2Si2PO12 solid‐state electrolyte is one of the prime candidates for Na metal solid‐state batteries due to its high room‐temperature ionic conductivity and electrochemical stability. However, a major challenge lies in integration of NASICONs with a Na anode due to the solid‐solid nature of the interface. Herein, the ductility of Na metal is capitalized and the impact of stack pressure and temperature in improving the interfacial properties of Na|NASICON symmetric cells is investigated. At 100 MPa stack pressure and 50 °C, the voltage polarization of the cells is approximately 10 times lower than those tested at 25 °C. The improved Na+‐ion kinetics result in a higher critical current density and a stable Na cycling response over long durations. Postmortem studies confirm the presence of Na dendrites in the pores and along the grain boundary of the NASICON ceramic structure. The results demonstrate the dependence of interface kinetics on pressure and temperature in a Na3Zr2Si2PO12‐based all‐solid state Na metal battery and presents a strategy for enabling stable operation of high‐energy, solid‐state Na batteries.

Solid sodium-ion batteries (SSIBs) with high safety and high energy density have broad application prospects. Unfortunately, the poor contact and dendrite growth between sodium and the solid electrolyte severely hinder their development. Herein, an in-situforming electron-blocking interlayer (EBI) has been designed on the surface of Na 3.2 Hf 1.9 Ca 0.1 Si 2 PO 12 (NHSP). The EBI could effectively improve the interface wetting and block the transmission of electrons, so as to ensure the long-term stability between sodium and the NHSP electrolyte. The batteries with the EBI@NHSP electrolyte could cycle stably for more than 700 h at 0.2 mA cm −2 . Even with the increase of the current density to 2.3 mA cm −2 , the batteries could still work normally. The full cell with the Na 3 V 2 (PO 4 ) 3 cathode also exhibited a good long-term cycling stability, which could cycle stably for more than 300 cycles at 0.5 C while maintaining a high Coulombic efficiency of 99.76%. This work provides a new feasible strategy to prevent sodium dendrite growth and promote the development of SSIBs.

“…22 Recently, we have systematically studied the effects of surface chemistry on the macroscopic performance of NZSP electrolyte. 34 However, the wettability of sodium to the electrolyte has not been discussed, and a direct evaluation of sodium wettability as a function of surface chemistry of the ceramic electrolyte is also lacking. Moreover, it is rather challenging to reveal the intrinsic wettability of the electrolyte using the traditional contact angle measurement, as the macroscopic wettability is a combined result of surface chemistry and microstructure.…”

The surface feature of solid electrolytes fundamentally governs their own physical properties and significantly affects the interaction with the electrode materials. The evaluation of interfacial contact between the electrolyte and the metallic anode is largely relied on the macroscopic contact angle measurement, which is influenced by the intrinsic wettability and the microstructure of the electrolyte. In this work, the surface chemistry of the solid electrolyte is first regulated via facile thermal treatments. Then, scanning probe microscopy (SPM)-based techniques are comprehensively adopted to study the interaction between the electrolyte and metallic anode at the nanoscale. By manipulating the overpotential applied on the SPM tip, the mobile sodium ions at the subsurface of the solid electrolyte can be extracted toward the surface, and the eventual topography of the products is deliberately correlated with the sodium wettability. In this context, the impact of surface treatment on the sodium wettability of the surface layer is systematically evaluated based on the topographic evolution at the nanoscale. Furthermore, the local electrochemical reaction dynamics is revealed by correlating the surface ionic activity and current−voltage (I−V) curves. This work presents a new methodology to effectively evaluate the sodium wettability of the solid electrolyte, and these findings can provide meaningful implications to the surface engineering of ceramic electrolytes for high-performance solid-state batteries.
