This invention outlines an ultrafast synthesis route for superionic sulfide solid electrolytes using microwave heating. This method significantly reduces the synthesis time and cost, making it a viable alternative to traditional heating methods for producing lithium silicon phosphorus sulfide (LSiPS) solid electrolytes for all-solid-state lithium batteries.
Current lithium-ion batteries with liquid electrolytes suffer from safety hazards, including low thermal stability and flammability. Traditional synthesis methods for solid electrolytes are time-consuming and costly, hindering their commercial application in advanced battery technologies.
- Ultrafast synthesis in just 30 minutes, reduces time by 16-144 times as compared to conventional methods.
- It is a cost-effective method as it eliminates the need for expensive vacuum sealing and argon gas purging, simplifying the process.
- The high-performance electrolyte delivers a high ionic conductivity (2.42 mS/cm) suitable for commercial applications.
- High fraction (~89%) of the high-conducting tetragonal phase in the synthesized product.
- The simplified process makes the synthesis more accessible for large-scale production.
