“…Figure S2 (Supporting Information) shows XRD patterns of pure PEO, PL, and PL‐10L. The diffractions at ≈19° and ≈23° correspond to characteristic diffractions of PEO, [ 54 ] and are observed in all membranes. With the introduction of the LLZTO@3 W hybrid fillers to a solid polymer membrane, the characteristic diffractions of PEO weakened ( Figure a), demonstrating the enlargement of the amorphous region in the PEO matrix as a result of the LLZTO@3 W hybrid fillers' disruptive impact on the crystallization of the polymer.…”

“…The solid‐state method was employed to synthesized cubic Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) powder. [ 53 ] To elaborate, precise amounts of high‐quality LiOH, La 2 O 3 , ZrO 2 , and Ta 2 O 5 , along with an additional excess amount of LiOH (15 wt.%) were used to compensate for lithium loss during high‐temperature calcination. These precursor materials were then dispersed in an isopropanol medium and ball‐milled for 36 h. The resulting mixture was subjected to drying at 60 °C for 12 h to remove the solvent, followed by calcination at 950 °C for a duration of 3 h. The end product was pulverized into a fine powder and subsequently sifted through 200‐mesh sieves.…”

“…The as‐prepared LLZTO powder was mixed with tungsten trioxide (WO 3 ; synthesis through hydrothermal process, [ 54 ] ) (1, 3, and 5 wt.%) using isopropyl alcohol as a medium. The mixture was ball milled for at least 12 h. The obtained composite mixture was kept in an oven at 60 °C for 12 h to evaporate the solvent and then calcined at 1100 °C for 6 h. Before utilization, the final product was transferred into a glove box filled with argon.…”

“…[47][48][49] Another strategy involves utilizing surface modification techniques like plasma treatment or chemical functionalization to improve the chemical compatibility between LLZTO and the electrode materials. [50][51][52][53] Enhancing the functionality of LLZTO garnet fillers through surface modification has been recognized as a promising approach. Nevertheless, despite these endeavors, the interfacial resistance between SPEs and Li metal anodes is yet to be fully mitigated.…”

The limited ionic conductivity at room temperature and the constrained electrochemical window of poly(ethylene oxide) (PEO) pose significant obstacles that hinder its broader utilization in high‐energy‐density lithium metal batteries. The garnet‐type material Li6.4La3Zr1.4Ta0.6O12 (LLZTO) is recognized as a highly promising active filler for enhancing the performance of PEO‐based solid polymer electrolytes (SPEs). However, its performance is still limited by its high interfacial resistance. In this study, a novel hybrid filler‐designed SPE is employed to achieve excellent electrochemical performance for both the lithium metal anode and the LiFePO4 cathode. The solid composite membrane containing hybrid fillers achieves a maximum ionic conductivity of 1.9 × 10−4 S cm−1 and a Li+ transference number of 0.67 at 40 °C, respectively. Additionally, the Li/Li symmetric cells demonstrate a smooth and stable process for 2000 h at a current density of 0.1 mA cm−2. Furthermore, the LiFePO4/Li battery delivers a high‐rate capacity of 159.2 mAh g−1 at 1 C, along with a capacity retention of 95.2% after 400 cycles. These results validate that employing a composite of both active and inactive fillers is an effective strategy for achieving superior performance in all‐solid‐state lithium metal batteries (ASSLMBs).

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.
