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.
The present 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.
- Ultrafast synthesis in just 30 minutes, reducing time by 16-144 times compared to conventional methods.
- Cost-effective method as it eliminates the need for expensive vacuum sealing and argon gas purging, simplifying the process.
- 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.
- Simplified process makes the synthesis more accessible for large-scale production.
The technology has been successfully demonstrated with the synthesis of LSiPS solid electrolytes, showcasing significant improvements in synthesis time and ionic conductivity.
