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%.

The Cost

The ionic conductivity of a Li–Al–Ge–P–S based thio-LISICON solid electrolyte is equivalent to that of a conventional organic liquid electrolyte used in lithium secondary batteries. The usage of aluminum brings down the cost of the solid electrolyte making it suitable for commercial solid state batteries.

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.

Highly conductive glass-ceramic electrolytes are successfully prepared in the system Li 2 S - P 2 S 5 with 70 and 80 mol% Li 2 S . The conductivities of these electrolytes are respectively 3.2 × 10-3 and 1.0 × 10-3 S cm -1 at room temperature. The precipitated crystals upon heat treatment of the glass are new superionic phase Li 7 P 3 S 11 and thio-LISICON II analog Li 3+5x P 1-x S 4, respectively. The crystal structure of the new phase Li 7 P 3 S 11 is analyzed and found to have a triclinic unit cell with space group of P-1 and to contain [Formula: see text] and [Formula: see text] ions. All-solid-state batteries using the Li 2 S - P 2 S 5 glass-ceramics are fabricated in order to evaluate the cell performance as a lithium secondary battery. The cells In /80 Li 2 S ·20 P 2 S 5 (mol%) glass-ceramic/ LiCoO 2 exhibit excellent cycling performance of over 500 times with no decrease in the discharge capacity (100 mAh g-1) at limited current densities. They also worked under very high current densities of 10 mA cm-2 when oxide- or sulfide-coated LiCoO 2 particles were used as an active material.

All-solid-state batteries (ASSBs) have attracted much attention in recent years, due to their high energy density, excellent cycling performance, and superior safety property. As the key factor of all-solid-state batteries, solid electrolyte determines the performance of the batteries. Garnet-typed cubic Li7La3Zr2O12(LLZO) has been reported as the most promising solid electrolyte on the way to ASSBs. Thin film electrolyte could contribute to a higher energy density and a lower resistance in a battery. This short review exhibits the latest efforts on LLZO thin film and discusses the different preparation methods, together with their effects on characteristics and electrochemical performances of the solid electrolyte film.

Solid-state battery (SSB) is the new avenue for achieving safe and high energy density energy storage in both conventional but also niche applications. Such batteries employ a solid electrolyte unlike the modern-day liquid electrolyte-based lithium-ion batteries and thus facilitate the use of high-capacity lithium metal anodes thereby achieving high energy densities. Despite this promise, practical realization and commercial adoption of solid-state batteries remain a challenge due to the underlying material and cell level issues that needs to be overcome. This chapter thus covers the specific challenges, design principles and performance improvement strategies pertaining to the cathode, solid electrolyte and anode used in solid state batteries. Perspectives and outlook on specific applications that can benefit from the successful implementation of solid-state battery systems are also discussed. Overall, this chapter highlights the potential of solid-state batteries for successful commercial deployment in next generation energy storage systems.
