Lithium ion-containing Na + Super Ionic Conductor (NASICON) electrolytes are important materials for new energystorage technologies. The NASICON abbreviation represents several compounds with similar structures applied as solid electrolytes, including those conductors of lithium ions. Different methods have been used to synthesize these materials, as well as innumerous other methods used to form the electrolyte in its final shape. The synthesis methods and processing techniques significantly affect the microstructure and conductivity of the electrolyte as a result. Therefore, this paper provides an overview of the main synthesis methods and processing techniques applied for lithium ion NASICON production. First, a general view of the NASICON structure and the variety of possible compositions will be discussed. Next, the influence of the synthesis methods (e.g., solid-state reaction, sol−gel, polymeric precursor, sol−gel/ electrospinning) and sintering techniques (e.g., conventional, microwave, and Spark Plasma Sintering) will be presented. A special topic will be devoted for glass-ceramics production and evaluation, based on their advantageous ionic conductivity and potentiality for practical use on a large-scale. Moreover, the current results for electrochemical cells simulating the application of these materials in batteries will be presented. Finally, a general point of view of the authors about the future for NASICON electrolytes will be provided, presenting oncoming trends for research.

This composition has since been synthesized/processed by different methods, such as solid‐state reaction, 16 Pechini, 17 sol‐gel, 18–20 spark‐plasma sintering (SPS), 21,22 ultrafast high‐temperature sintering (UHS), 23 microwave sintering, 24,25 cold sintering, 26 and glass‐ceramic route (melt‐quenching followed by controlled crystallization) 27 . The highest ionic conductivity (∼10 −3 S cm −1 ) was obtained with the glass‐ceramic route.…”

Ultrafast crystallization and sintering of Li_1.3Al_0.3Ti_1.7(PO₄)₃ glass through flash sinter‐crystallization

Flash sinter‐crystallization (FSC) is a new technique for concurrently crystallizing and sintering glasses, derived from flash sintering. In this study, we explore, for the first time, the use of FSC as a processing method for producing Li1.3Al0.3Ti1.7(PO4)3 (LATP) glass‐ceramics. Using FSC, LATP with NaSICON structure is produced at a furnace temperature as low as 460°C and a processing time of 5 min. The FSC‐processed samples with different current density limits were compared with those conventionally sinter‐crystallized (CSC) at 950°C for 1 h. We show that FSC can significantly improve the densification of LATP glass‐ceramics due to the volumetric high heating rate. Furthermore, the LATP samples processed by FSC exhibit superior total ionic conductivity than those processed by CSC, also surpassing the reported results for LATP with similar levels of densification. Therefore, our results suggest that FSC is a promising method for processing glass‐ceramics, particularly for materials with high crystallization kinetics like LATP, opening up new possibilities for the production of solid‐electrolytes.This article is protected by copyright.

“…To date, most cathode materials in LIBs have focused on metal oxides, such as LiCoO 2 , LiMn 2 O 4 , and LiNi x Mn y Co (1− x − y ) O 2 , due to their reasonable capacity, compact structures, and high electric conductivity 37–39 . To use these metal oxides in SSBs, usually, they are sintered with metal oxide electrolytes, such as perovskite‐ or garnet‐type materials, which can induce the formation of a strong and densified electrode–electrolyte interface 40–44 . However, this sintering process also gives rise to issues of cation interdiffusion and structural change at the solid–solid interface, where the side reaction compounds will retard the Li + diffusion across the interface and thus compromise the rate and power capability.…”

In situ characterizations of solid–solid interfaces in solid‐state batteries using synchrotron X‐ray techniques

The solid–solid electrode–electrolyte interface represents an important component in solid‐state batteries (SSBs), as ionic diffusion, reaction, transformation, and restructuring could all take place. As these processes strongly influence the battery performance, studying the evolution of the solid–solid interfaces, particularly in situ during battery operation, can provide insights to establish the structure–property relationship for SSBs. Synchrotron X‐ray techniques, owing to their unique penetration power and diverse approaches, are suitable to investigate the buried interfaces and examine structural, compositional, and morphological changes. In this review, we will discuss various surface‐sensitive synchrotron‐based scattering, spectroscopy, and imaging methods for the in situ characterization of solid–solid interfaces and how this information can be correlated to the electrochemical properties of SSBs. The goal is to overview the advantages and disadvantages of each technique by highlighting representative examples, so that similar strategies can be applied by battery researchers and beyond to study similar solid‐solid interface systems.
