Solid electrolyte is the key component in all-solid-state batteries (ASBs). It is required in electrodes to enhance Li-conductivity and can be directly used as a separator. With its high Li-conductivity and chemical stability towards metallic lithium, lithium-stuffed garnet material Li7La3Zr2O12 (LLZO) is considered one of the most promising solid electrolyte materials for high-energy ceramic ASBs. However, in order to obtain high conductivities, rare-earth elements such as tantalum or niobium are used to stabilize the highly conductive cubic phase. This stabilization can also be obtained via high levels of aluminum, reducing the cost of LLZO but also reducing processability and the Li-conductivity. To find the sweet spot for a potential market introduction of garnet-based solid-state batteries, scalable and industrially usable syntheses of LLZO with high processability and good conductivity are indispensable. In this study, four different synthesis methods (solid-state reaction (SSR), solution-assisted solid-state reaction (SASSR), co-precipitation (CP), and spray-drying (SD)) were used and compared for the synthesis of aluminum-substituted LLZO (Al:LLZO, Li6.4Al0.2La3Zr2O12), focusing on electrochemical performance on the one hand and scalability and environmental footprint on the other hand. The synthesis was successful via all four methods, resulting in a Li-ion conductivity of 2.0–3.3 × 10−4 S/cm. By using wet-chemical synthesis methods, the calcination time could be reduced from two calcination steps for 20 h at 850 °C and 1000 °C to only 1 h at 1000 °C for the spray-drying method. We were able to scale the synthesis up to a kg-scale and show the potential of the different synthesis methods for mass production.

AbstractDue to their high conductivity and interface formability, sulfide electrolytes are attractive for use in high energy density all-solid-state batteries. However, electrode volume changes during charge-discharge cycling typically cause mechanical contact losses at the electrode/electrolyte interface, which leads to capacity fading. Here, to suppress this contact loss, isolated PS43- anions are reacted with iodine to prepare a sulfide polymer electrolyte that forms a sticky gel during dispersion in anisole and drying of the resulting supernatant. This polymer, featuring flexible (–P–S–S–)n chains and enhanced solubility in anisole, is applied as a lithium-ion-conductive binder in sheet-type all-solid-state batteries, creating cells with low resistance and high capacity retention.

ABSTRACTHighly ion-conductive Li6PS5Cl Li-argyrodites were prepared through a high energy ball milling. Electrical and electrochemical properties were investigated. Ball-milled compounds exhibit a high conductivity of 1.33×10−4 S/cm with an activation energy of 0.3-0.4 eV and an electrochemical stability up to 7V vs. lithium. These results are obtained after only 10 hours of milling and with no additional heat treatment.To validate the use of the Li6PS5Cl-based solid electrolyte, all-solid-state batteries using LiCoO2 and Li4Ti5O12 as active material have been realized. The optimization of the electrode composition led to a maximum of 46 and 27 mAh per gram of composite for LiCoO2 and Li4Ti5O12-based half-cells respectively. The assembled all-solid-state LiCoO2 / Li6PS5Cl / Li4Ti5O12 battery presents a sustainable reversible capacity of 27 mAh per gram of active material and a coulomb efficiency close to 99%.
