Semiconductor devices such as transistors are essential to these technologies, and they are constantly being improved by being made smaller and more integrated. However, there is a concern that these improvements may slow down in the near future. Thus, creating new types of devices that can overcome the problems and/or enhance the capabilities of traditional semiconductor devices has become an important challenge. In particular, solid-state ionic devices can potentially meet this challenge. In this review, we describe the design of such devices using ionic nanoarchitectonics techniques that locally control ion conduction and electrochemical behavior in ion conductors and mixed conductors.

In this work, we present a comprehensive review of DFT-based studies, focusing on site occupancies and transport mechanisms that govern the Li⁺ conduction in NaSICONs. The reported site and migration energies show significant variations, primarily attributed to differences in the size of the calculated supercells. Despite these discrepancies, our analysis confirms that both vacancy-assisted and interstitial migration occur in the NaSICON structure, with the latter being crucial for enabling superionic conduction.

The state-of-the-art fuel electrode of such cells, a Ni-zirconia composite, suffers from some limitations: poor durability at high polarization, sensitivity to detrimental coke formation, and limited redox stability. Electrodes made from perovskite materials may offer a solution to these challenges; they show a reduced tendency for coke formation and have the potential to enhance stability and performance. To this end, developing perovskite materials with enhanced mixed ionic and electronic conductivity (MIEC) and the capacity to exsolve nanoparticles to boost performance is important. This study introduces a defect chemistry model for a promising “exsolution” material (La_0.49Sr_0.31Ti_0.94Fe_0.03Ni_0.03O_3, LSFNT) and reports on the transport properties of the material. LSFNT retains a stable cubic perovskite structure across a wide oxygen partial pressure range (0.21 to 10⁻²¹ bar) and ex-solves Ni_1-<em>x</em>Fe_<em>x</em> nanoparticles in pure hydrogen. The conductivity of LSFNT increases with decreasing oxygen partial pressure, displaying an approximate <span><math><msup><msub><mi>pO</mi><mn>2</mn></msub><mrow><mo>−</mo><mn>1</mn><mo>/</mo><mn>6</mn></mrow></msup></math></span> dependence in the range of 10⁻¹⁴ to 10⁻¹⁸ bar.

This work also demonstrates the mixed ionic and electronic conductivity in LSFNT. Electron-blocking experiments reveal a high ionic conductivity of LSFNT (0.054 S/cm at 850 °C), which exceeds that of yttria-stabilized zirconia (8YSZ) and is comparable to gadolinium-doped ceria (Ce_0.9Gd_0.1O₂, CGO).

This study examines Y and Pr co-doped Ce_1-xY_x/2Pr_x/2O_2-δ (x = 0–0.30) electrolytes for IT-SOFCs. The synthesized compositions are characterized to assess their functional properties. All samples formed cubic fluorite structures at 600 °C. YPDC20 shows the highest relative density (94.8 %) and, the smallest grain size, highest dislocation density, and largest micro strain. X-ray photoelectron spectroscopy (XPS) reveals the mixed valence states of cerium (Ce⁴⁺/Ce³⁺) in both CeO₂ and YPDC20, along with coexisting Pr³⁺/Pr⁴⁺ states in YPDC20. Electrochemical impedance spectroscopy combined with capacitance calculations confirms significant differences in the contributions of grain, grain boundary, and electrode components. The study reveals that for YPDC05, the characteristic grain boundary resistance arc shifts to higher frequencies with increasing temperature, with only electrode response observed at 800 °C. As doping concentration increases, the disappearance temperature of grain boundary response significantly decreases: YPDC10 exhibits only electrode contribution at 700 °C, while higher-doped samples (x &gt; 0.10) reached this state at 600 °C. Notably, YPDC20 demonstrates optimal performance, achieving an ionic conductivity of 1.2 × 10⁻¹ S cm⁻¹ at 800 °C—nearly two orders of magnitude higher than undoped CeO₂. This performance enhancement primarily stems from the dual effects of Y/Pr co-doping: the introduction of cations (Y³⁺/Pr^3+/4+) significantly increases oxygen vacancy concentration, while the optimized microstructure provides fast transport channels for oxygen ions. These characteristics make YPDC20 a highly promising electrolyte material for IT-SOFCs.</div></div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"429 ","pages":"Article 116993"},"PeriodicalIF":3.3,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144771402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigated the effect of solid electrolyte particle size on the voids and tortuosity of solid electrolyte in composite electrode and electrochemical performance of composite electrodes using in situ X-ray computed tomography. The results showed that fine Li₃PS₄ resulted in better packing and lowering tortuosity to increasing pressure compared to large Li₃PS₄, which enhanced the electrochemical performance, especially at higher pressure. A detailed analysis on shapes of voids revealed that plate-like voids with low elongation and flatness disappeared and more spherical voids with high elongation and flatness were emerged as external pressure increased. In addition, the voids in the composite electrode using fine Li₃PS₄ particles were less likely to interfere with Li-ion conduction pathways, which improved overall battery performance.

The reaction order analysis suggested a complex reaction mechanism, for which we came to think of two series kinetics, surface process and subsurface process. The former refers to an exchange process between gas-phase oxygen molecules and some sort of surface oxygen species. The latter refers to the exchange of surface oxygen with bulk oxide ions, and the reaction barrier is not necessarily oxygen transport, but may be electron transport/transfer for oxygen in/ex-corporation This hypothesis appeared to resolve some of our remaining questions regarding the experimental results, such as scattered &lt;em&gt;p&lt;/em&gt;&lt;sub&gt;O&lt;sub&gt;2&lt;/sub&gt;&lt;/sub&gt; dependence in high partial pressure range, the higher isotope exchange rates than electrochemical impedance, and the reaction rate enhancement in the presence of the LaSrCoO&lt;sub&gt;4&lt;/sub&gt; phase. While a single piece of such experimental evidence is insufficient to prove the hypothesis, considering all the results together provides strong support.
