“…Surprisingly, this loading-amount has not been reported before. As shown in Figure , this high-loading dry-electrode demonstrates excellent cycling stability compared to previous studies. − Even after 100 cycles, the dry-electrode with Z-LPSCl_5 wt % did not show any microcracks in the electrode (Table S4 and Figure S17) under repeated mechanical stress. This study validates the potential of the Z-LPSCl_5 wt % SE for high-loading and high-stability application in the exploration of advanced solid-state batteries.…”

For realizing all-solid-state batteries (ASSBs), it is highly desirable to develop a robust solid electrolyte (SE) that has exceptional ionic conductivity and electrochemical stability at room temperature. While argyrodite-type Li 6 PS 5 Cl (LPSCl) SE has garnered attention for its relatively high ionic conductivity (∼3.19 × 10 −3 S cm −1 ), it tends to emit hydrogen sulfide (H 2 S) in the presence of moisture, which can hinder the performance of ASSBs. To address this issue, researchers are exploring approaches that promote structural stability and moisture resistance through elemental doping or substitution. Herein, we suggest using zeolite imidazolate framework-8 as a moisture absorbent in LPSCl without modifying the structure of the SE or the electrode configuration. By incorporating highly ordered porous materials, we demonstrate that ASSBs configured with LPSCl SE display stable cyclability due to effective and long-lasting moisture absorption. This approach not only improves the overall quality of ASSBs but also lays the foundation for developing a moisture-resistant sulfide electrolyte.

“…We attribute this difference in the ionic conductivities to the better contact between the inorganic particles when the SEBS block copolymer is squeezed under temperature and pressure, enabling faster lithium hopping. 31 The optimized processing temperature was 200 °C, which led to conductivities close to 10 −4 S/cm at RT. For that reason, the temperature of 200 °C was chosen for both blend HSE and in situ HSE processing (Figure 1b).…”

“…The increase of the processing temperature from 150 to 200 °C led to an increase by a factor of about 30 of the ionic conductivity, and then it slightly decreased when the HSE was processed at 250 °C. We attribute this difference in the ionic conductivities to the better contact between the inorganic particles when the SEBS block copolymer is squeezed under temperature and pressure, enabling faster lithium hopping . The optimized processing temperature was 200 °C, which led to conductivities close to 10 –4 S/cm at RT.…”

The translation of inorganic−polymer hybrid battery materials from laboratory-scale to industry-relevant battery manufacturing processes is difficult due to their complexity, scalability, and cost and the limited fundamental knowledge that is available. Herein, we introduce a unique and compelling approach for the preparation of hybrid solid electrolytes based on an in situ synthesized halide electrolyte (Li 3 InCl 6 ) in the presence of a nonconducting polymer (styrene−ethylene−butylene−styrene block copolymer). This innovative in situ approach delivers flexible selfstanding membranes with good ionic conductivity (0.7 × 10 −4 S/ cm at 30 °C) and low activation energy (0.25 eV). This study suggests that the total conductivity is dominated by the inorganic− polymer interfaces and the microstructure of the hybrids affects the energy barriers to ion transport. This work opens a promising sustainable and cost-efficient route that can be easily implemented in current battery manufacturing lines.

Consequently, extensive research has been conducted on LPSCl electrolytes, yielding promising results for their applications in Li-ion and Li–S batteries. − However, a significant challenge in using argyrodite LPSCl in ASSLBs applications is the interface instability between LPSCl and electrodes. During CD cycling, LPSCl tends to oxidize, leading to the production of elemental sulfur, polysulfides, phosphates, and lithium chloride at the electrode interface. , These side products ultimately hinder the cycling stability and can result in dendrite formation at the interface.…”

Solid-state batteries (SSBs) that incorporate the argyrodite-Li 6 PS 5 Cl (LPSCl) electrolyte hold potential as substitutes for conventional lithium-ion batteries (LIBs). However, the mismatched interface between the LPSCl electrolyte and electrodes leads to increased interfacial resistance and the rapid growth of lithium (Li) dendrites. These factors significantly impede the feasibility of their widespread industrial application. In this study, we developed a composite electrolyte of the LPSCl/polymer to enhance the contact between the electrolyte and electrodes and suppress dendrite formation at the grain boundary of the LPSCl ceramic. The monomer, triethylene glycol dimethacrylate (TEGDMA), is utilized for in situ polymerization through thermal curing to create the argyrodite LPSCl/ polymer composite electrolyte. Additionally, the ball-milling technique was employed to modify the morphology and particle size of the LPSCl ceramic. The ball-milled LPSCl/polymer composite electrolyte demonstrates slightly higher ionic conductivity (ca. 2.21 × 10 −4 S/cm) compared to the as-received LPSCl/polymer composite electrolyte (ca. 1.65 × 10 −4 S/cm) at 25 °C. Furthermore, both composite electrolytes exhibit excellent compatibility with Li-metal and display cycling stability for up to 1000 h (375 cycles), whereas the asreceived LPSCl and ball-milled LPSCl electrolytes maintain stability for up to 600 h (225 cycles) at a current density of 0.4 mA/cm 2 . The SSB with the ball-milled LPSCl/polymer composite electrolyte delivers high specific discharge capacity (138 mA h/g), Coulombic efficiency (99.97%), and better capacity retention at 0.1C, utilizing the battery configuration of coated NMC811// electrolyte//Li-Indium (In) at 25 °C.
