“…This may be related to the slightly different composition of the material when sintered at 800, 900, or 1000 °C. Based on this fact, different values were reported for grain and total activation energy [5,7,9,12,14,[17][18][19]23,24,26,[28][29][30]35,48]. The values of the apparent grain and total conductivity can be calculated by employing the equation σ = L/(R•A), where L and A represent the sample thickness and electrode area.…”

“…In the NASICON-type structure, TiO 6 octahedra and PO 4 tetrahedra are linked by their corners to form a 3D stable network [5][6][7][8]. However, its total ionic conductivity is still low because of highly resistive grain boundaries and low sinterability [8][9][10][11][12][13][14][15]. To address that issues, the partial replacement of Ti 4+ ions by trivalent Al 3+ ions was adopted as a way to improve sinterability and enhance the ionic conductivity.…”

“…To address that issues, the partial replacement of Ti 4+ ions by trivalent Al 3+ ions was adopted as a way to improve sinterability and enhance the ionic conductivity. Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) displayed a total ionic conductivity as high as 10 −4 S/cm at room temperature, depending on the preparation procedure [8][9][10][11][12][13][14][16][17][18][19][20][21][22]. Moreover, the compound exhibits good thermal and mechanical stability, good chemical stability against moisture in air, negligible electronic conductivity, and low costs, making it suitable for large-scale production.…”

The currently studied materials considered as potential candidates to be solid electrolytes for Li-ion batteries usually suffer from low total ionic conductivity. One of them, the NASICON-type ceramic of the chemical formula Li1.3Al0.3Ti1.7(PO4)3, seems to be an appropriate material for the modification of its electrical properties due to its high bulk ionic conductivity of the order of 10−3 S∙cm−1. For this purpose, we propose an approach concerning modifying the grain boundary composition towards the higher conducting one. To achieve this goal, Li4SiO4 was selected and added to the LATP base matrix to support Li+ diffusion between the grains. The properties of the Li1.3Al0.3Ti1.7(PO4)3−xLi4SiO4 (0.02 ≤ x ≤ 0.1) system were studied by means of high-temperature X-ray diffractometry (HTXRD); 6Li, 27Al, 29Si, and 31P magic angle spinning nuclear magnetic resonance spectroscopy (MAS NMR); thermogravimetry (TG); scanning electron microscopy (SEM); and impedance spectroscopy (IS) techniques. Referring to the experimental results, the Li4SiO4 additive material leads to the improvement of the electrical properties and the value of the total ionic conductivity exceeds 10−4 S∙cm−1 in most studied cases. The factors affecting the enhancement of the total ionic conductivity are discussed. The highest value of σtot = 1.4 × 10−4 S∙cm−1 has been obtained for LATP–0.1LSO material sintered at 1000 °C for 6 h.

“…Boron trioxide, B 2 O 3 has been used not only as an additive improving the glass-forming properties of the melt but also as an agent influencing the crystallization kinetics and impeding the precipitation of secondary, unwanted phases [38][39][40][41]. In our previous study [42] we investigated this effect and showed that the ionic conductivity of LATP-based glass-ceramics can be increased due to B 2 O 3 addition. If the parent LATP glass is prepared by melt quenching, the high melting temperatures lead to the lithium loss.…”

Two families of glasses in the Li2O-Al2O3-B2O3-TiO2-P2O5 system were prepared via two different synthesis routes: melt-quenching and ball-milling. Subsequently, they were submitted to crystallization and yielded the Li1.3Al0.3Ti1.7(PO4)3 (LATP)-based glass-ceramics. Glasses and corresponding glass-ceramics were studied by complementary X-ray diffraction (XRD) and 27Al, 31P, 7Li, 11B magic-angle spinning nuclear magnetic resonance (MAS NMR) methods in order to compare their structure and phase composition and elucidate the impact of boron additive on their glass-forming properties and crystallization process. XRD studies show that the addition of B2O3 improves the glass-forming properties of glasses prepared by either method and inhibits the precipitation of unwanted phases during heat treatment. MAS NMR studies allowed us to distinguish two LATP phases of slightly different chemical composition suggesting that LATP grains might not be homogeneous. In conclusion, the crystallization of boron-incorporated LATP glasses can is an effective way of obtaining LATP-based solid state electrolytes for the next generation of lithium-ion batteries provided the proper heat-treatment conditions are chosen.

The main purpose of this review is to present comprehensive research on all solid‐state electrolytes in a single frame. In next‐generation rechargeable solid‐state batteries, the solid‐state electrolytes are well known for their thermal stability, ionic conduction, and electrochemical stability. Therefore, in scientific societies, the development of potential solid‐state electrolytes become a trending debate to enhance their cycling stability and electrochemical properties. Here, the recent development of all solid electrolytes (such as ceramic and structure‐based electrolytes) to enhance their electrochemical properties is summarized. From previous studies, the installation of solid electrolytes is hindered by the following factors electrode‐electrolyte interface, dendrite growth, and discharge capacity as well as its solutions are discussed. Additionally, advanced electrochemical characterization techniques such as electrochemical impedance spectroscopy, cyclic voltammetry, and galvanostatic charging and discharging used to evaluate the electrochemical behavior of electrolytes in the solid frame are summarized for the first time. Moreover, an up‐to‐date article on battery performance with potential electrolytes and some future perspectives also give a vivid image of the pragmatic applications of these batteries at the commercial level.
